For an example data in your table such as combinations of

'', null and as well as actual value than if you want to only actual value and replace to '' and null value by # symbol than execute this query

SELECT Column_Name = (CASE WHEN (Column_Name IS NULL OR Column_Name = '') THEN '#' ELSE Column_Name END) FROM Table_Name

and another way you can use it but this is little bit lengthy and instead of this you can also use IsNull function but here only i am mentioning IIF function

SELECT IIF(Column_Name IS NULL, '#', Column_Name) FROM Table_Name  
SELECT IIF(Column_Name  = '', '#', Column_Name) FROM Table_Name  
-- and syntax of this query
SELECT IIF(Column_Name IS NULL, 'True Value', 'False Value') FROM Table_Name

Consider an If Else condition. A continue statement executes what is there in a condition and gets out of the condition i.e. jumps to next iteration or condition. But a Break leaves the loop. Consider the following Program. '

public class ContinueBreak {
    public static void main(String[] args) {
        String[] table={"aa","bb","cc","dd"};
        for(String ss:table){
            if("bb".equals(ss)){
                continue;
            }
            System.out.println(ss);
            if("cc".equals(ss)){
                break;
            }
        }
        System.out.println("Out of the loop.");
    }

}

It will print: aa cc Out of the loop.

If you use break in place of continue(After if.), it will just print aa and out of the loop.

If the condition "bb" equals ss is satisfied: For Continue: It goes to next iteration i.e. "cc".equals(ss). For Break: It comes out of the loop and prints "Out of the loop. "

In Python 3.8 the dirs_exist_ok keyword argument was added to shutil.copytree():

dirs_exist_ok dictates whether to raise an exception in case dst or any missing parent directory already exists.

So, the following will work in recent versions of Python, even if the destination directory already exists:

shutil.copytree(src, dest, dirs_exist_ok=True)  # 3.8+ only!

One major benefit is that it's more flexible than distutils.dir_util.copy_tree() as it takes additional arguments on files to ignore, etc. There is also a draft PEP (PEP 632, associated discussion), which suggests that distutils may be deprecated and then removed in future versions of Python 3.

You need the "correlation id" (the "AS SS" thingy) on the sub-select to reference the fields in the "ON" condition. The id's assigned inside the sub select are not usable in the join.

SELECT
       cs.CUSID
       ,dp.DEPID
FROM
    CUSTMR cs
        LEFT OUTER JOIN (
            SELECT
                    DEPID
                    ,DEPNAME
                FROM
                    DEPRMNT 
                WHERE
                    dp.DEPADDRESS = 'TOKYO'
        ) ss
            ON (
                ss.DEPID = cs.CUSID
                AND ss.DEPNAME = cs.CUSTNAME
            )
WHERE
    cs.CUSID != '' 

If you are using Rating bar in Linearlayout with weightSum. Please make sure that you should not assign the layout_weight for rating bar. Instead, that place rating bar inside relative layout and give weight to the relative layout. Make rating bar width wrap content.

<RelativeLayout
    android:layout_width="0dp"
    android:layout_weight="30"
    android:layout_gravity="center"
    android:layout_height="wrap_content">
        <RatingBar
            android:id="@+id/userRating"
            style="@style/Widget.AppCompat.RatingBar.Small"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:stepSize="1" />
</RelativeLayout>

Another solution create generic list of anonymous type.

 var list = new[]
 { 
    new { Number = 10, Name = "Smith" },
    new { Number = 10, Name = "John" } 
 }.ToList();

 foreach (var item in list)
 {
    Console.WriteLine(item.Name);
 }

This also gives you intellisense support, I think in some situations its better than Tuple and Dictionary.

I had some trouble with this - my EntityKey consists of three properties (PK with 3 columns) and I didn't want to check each of the columns because that would be ugly. I thought about a solution that works all time with all entities.

Another reason for this is I don't like to catch UpdateExceptions every time.

A little bit of Reflection is needed to get the values of the key properties.

The code is implemented as an extension to simplify the usage as:

context.EntityExists<MyEntityType>(item);

Have a look:

public static bool EntityExists<T>(this ObjectContext context, T entity)
        where T : EntityObject
    {
        object value;
        var entityKeyValues = new List<KeyValuePair<string, object>>();
        var objectSet = context.CreateObjectSet<T>().EntitySet;
        foreach (var member in objectSet.ElementType.KeyMembers)
        {
            var info = entity.GetType().GetProperty(member.Name);
            var tempValue = info.GetValue(entity, null);
            var pair = new KeyValuePair<string, object>(member.Name, tempValue);
            entityKeyValues.Add(pair);
        }
        var key = new EntityKey(objectSet.EntityContainer.Name + "." + objectSet.Name, entityKeyValues);
        if (context.TryGetObjectByKey(key, out value))
        {
            return value != null;
        }
        return false;
    }

Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.

For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:

$ php -i | grep -i soap

to ensure that it is the PHP extension that is missing.

Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.

In Ubuntu/Debian you can search with:

$ apt-cache search php | grep -i soap

or in RHEL/Fedora you can search with:

$ yum search php | grep -i soap

There are usually two PHP SOAP packages available to you, usually php-soap and php-nusoap. php-soap is typically what you get with configuring PHP with --enable-soap.

In Ubuntu/Debian you can install with:

$ sudo apt-get install php-soap

Or in RHEL/Fedora you can install with:

$ sudo yum install php-soap

After the installation, you might need to place an ini file and restart Apache.

Make sure to backup your web.config

Swift 4+ approach:

1) Set UIScrollView top, bottom, left and right margins to 0

2) Inside the UIScrollView add a UIView and set top, bottom, leading, trailing margins to 0 ( equal to UIScrollView margins ).

3) The most important part is to set width and height, where height constraint should have a low priority.

private func setupConstraints() {

    // Constraints for scrollView
    scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
    scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
    scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
    scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true

    // Constraints for containerView
    containerView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
    containerView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
    containerView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
    containerView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
    containerView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true

    let heightConstraint = containerView.heightAnchor.constraint(equalTo: scrollView.heightAnchor)
    heightConstraint.priority = UILayoutPriority(rawValue: 250)
    heightConstraint.isActive = true
}

Your error is also shown when trying to access the sizeof() of an non-initialized extern array:

extern int a[];
sizeof(a);
>> error: invalid application of 'sizeof' to incomplete type 'int[]'

Note that you would get an array size missing error without the extern keyword.

They are case insensitive, unless you do a binary comparison.

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

My version without a loop would be like this:

echo implode(
    "\n", 
    array_map(
         function ($k, $v) { 
             return "$k is at $v"; 
         }, 
         array_keys($page), 
         array_values($page)
    )
);

If you have a built-in command of GridView like insert, update or delete, on row command you can use the following code to get the index:

int index = Convert.ToInt32(e.CommandArgument);

In a custom command, you can set the command argument to yourRow.RowIndex.ToString() and then get it back in the RowCommand event handler. Unless, of course, you need the command argument for another purpose.

Currently and unfortunately we can't do anything to stop the thread....

Adding something to Matt's answer we can call interrupt() but that doesn't stop thread... Just tells the system to stop the thread when system wants to kill some threads. Rest is done by system, and we can check it by calling interrupted().

[p.s. : If you are really going with interrupt() I would ask you to do some experiments with a short sleep after calling interrupt()]

I don't know of any methodology to use to fix things like this. I don't think it would be possible to come up with one either for the very issue at hand is that your program's behavior is undefined (I don't know of any case when SEGFAULT hasn't been caused by some sort of UB).

There are all kinds of "methodologies" to avoid the issue before it arises. One important one is RAII.

Besides that, you just have to throw your best psychic energies at it.

<hr> is not from struts. It is just an HTML tag.

So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.

I solved the problem by using the Rnd() function:

Function RollD6() As UInteger
        RollD6 = (Math.Floor(6 * Rnd())) + 1
        Return RollD6
End Function

When the form loads, I use the Randomize() method to make sure I don't always get the same sequence of random numbers from run to run.

Or if you want to check for existence first:

if [[ ! -e /path/to/newdir ]]; then
            mkdir /path/to/newdir
fi

-e is the exist test for KornShell.

You can also try googling a KornShell manual.

Another possibility is to select the Install Dependencies checkbox In the R package installer, on the bottom right:

You can use numpy:

import numpy as np

Example from Empty Array:

np.empty([2, 2])
array([[ -9.74499359e+001,   6.69583040e-309],
       [  2.13182611e-314,   3.06959433e-309]])  

TimeSpan.FromTicks( 28000000000 ).TotalMinutes;

Had a similar problem when find an object by id... All i did was to use the fully qualified name in the class name. That is Before it was :

find("Class",id)

Object so it became like this :

find("assemblyName.Class",id)

Open Oracle SQLDeveloper

Right click on connection tab and select new connection

Enter HR_ORCL in connection name and HR for the username and password.

Specify localhost for your Hostname and enter ORCL for the SID.

Click Test.

The status of the connection Test Successfully.

The connection was not saved however click on Save button to save the connection. And then click on Connect button to connect your database.

The connection is saved and you see the connection list.

If you're running a jar file with java -jar, the -classpath argument is ignored. You need to set the classpath in the manifest file of your jar, like so:

Class-Path: jar1-name jar2-name directory-name/jar3-name

See the Java tutorials: Adding Classes to the JAR File's Classpath.

Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':' after "Class-Path" like you showed, it would not work.

Follow,

$: git checkout -f

$: git checkout next_branch

It's complicated.

First of all, in this code

const p = new Promise((resolve) => {
    resolve(4);
});

the type of p is inferred as Promise<{}>. There is open issue about this on typescript github, so arguably this is a bug, because obviously (for a human), p should be Promise<number>.

Then, Promise<{}> is compatible with Promise<number>, because basically the only property a promise has is then method, and then is compatible in these two promise types in accordance with typescript rules for function types compatibility. That's why there is no error in whatever1.

But the purpose of async is to pretend that you are dealing with actual values, not promises, and then you get the error in whatever2 because {} is obvioulsy not compatible with number.

So the async behavior is the same, but currently some workaround is necessary to make typescript compile it. You could simply provide explicit generic argument when creating a promise like this:

const whatever2 = async (): Promise<number> => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

In ggplot2 you can do smooths in a number of ways, for example:

library(ggplot2)
ggplot(mtcars, aes(wt, mpg)) + geom_point() +
  geom_smooth(method = "gam", formula = y ~ poly(x, 2)) 
ggplot(mtcars, aes(wt, mpg)) + geom_point() +
  geom_smooth(method = "loess", span = 0.3, se = FALSE) 

break would stop the foreach loop completely, continue would skip to the next DataRow.

Assuming you have some level of control over the protocol, I'm a big fan of sending heartbeats to verify that a connection is active. It's proven to be the most fail proof method and will often give you the quickest notification when a connection has been broken.

TCP keepalives will work, but what if the remote host is suddenly powered off? TCP can take a long time to timeout. On the other hand, if you have logic in your app that expects a heartbeat reply every x seconds, the first time you don't get them you know the connection no longer works, either by a network or a server issue on the remote side.

See Do I need to heartbeat to keep a TCP connection open? for more discussion.

Use:

return [n]

From help return

return: return [n]

Return from a shell function.

Causes a function or sourced script to exit with the return value
specified by N.  If N is omitted, the return status is that of the
last command executed within the function or script.

Exit Status:
Returns N, or failure if the shell is not executing a function or script.

I tried everything on the post but nothing had worked. I then changed the .htaccess snippet that ErJab put up to read:

RewriteRule ^(.*)$ 'folder_name'/index.php/$1 [L]

The above line fixed it for me. where *folder_name* is the magento root folder.

jQuery supports CSS3 style selectors, plus some more.

How to address your textbox depends on the HTML-code:

<!-- 1 --><input type="textbox" id="Tue" />
<!-- 2 --><input type="textbox" name="Tue" />

If you use the 'id' attribute:

var textbox = document.getElementById('Tue');

for 'name':

var textbox = document.getElementsByName('Tue')[0]

(Note that getElementsByName() returns all elements with the name as array, therefore we use [0] to access the first one)

Then, use the 'value' attribute:

textbox.value = 'Foobar';

As far as I know, can't you just make it abstract?

class parent {
public:
  virtual void handle_event(int something) const = 0 {
    // boring default code
  }
};

I thought I read on www.parashift.com that you can actually implement an abstract method. Which makes sense to me personally, the only thing it does is force subclasses to implement it, no one said anything about it not being allowed to have an implementation itself.

I'm going to approach this as if you have a Users model:

Users.cs

public class Users
{
    [Key]
    public int UserId { get; set; }

    [Required]
    public string UserName { get; set; }

    public int RoleId { get; set; }

    [ForeignKey("RoleId")]
    public virtual DbUserRoles DbUserRoles { get; set; }
}

and a DbUserRoles model that represented a table by that name in the database:

DbUserRoles.cs

public partial class DbUserRoles
{
    [Key]
    public int UserRoleId { get; set; }

    [Required]
    [StringLength(30)]
    public string UserRole { get; set; }
}

Once you had that cleaned up, you should just be able to create and fill a collection of UserRoles, like this, in your Controller:

var userRoleList = GetUserRolesList();
ViewData["userRoles"] = userRolesList;

and have these supporting functions:

private static SelectListItem[] _UserRolesList;

/// <summary>
/// Returns a static category list that is cached
/// </summary>
/// <returns></returns>
public SelectListItem[] GetUserRolesList()
{
    if (_UserRolesList == null)
    {
        var userRoles = repository.GetAllUserRoles().Select(a => new SelectListItem()
         {
             Text = a.UserRole,
             Value = a.UserRoleId.ToString()
         }).ToList();
         userRoles.Insert(0, new SelectListItem() { Value = "0", Text = "-- Please select your user role --" });

        _UserRolesList = userRoles.ToArray();
    }

    // Have to create new instances via projection
    // to avoid ModelBinding updates to affect this
    // globally
    return _UserRolesList
        .Select(d => new SelectListItem()
    {
         Value = d.Value,
         Text = d.Text
    })
     .ToArray();
}

Repository.cs

My Repository function GetAllUserRoles() for the function, above:

public class Repository
{
    Model1 db = new Model1(); // Entity Framework context

    // User Roles
    public IList<DbUserRoles> GetAllUserRoles()
    {
        return db.DbUserRoles.OrderBy(e => e.UserRoleId).ToList();
    }
}

AddNewUser.cshtml

Then do this in your View:

<table>
    <tr>
        <td>
            @Html.EditorFor(model => model.UserName,
                  htmlAttributes: new { @class = "form-control" }
                  )
        </td>
        <td>
            @Html.DropDownListFor(model => model.RoleId,
                  new SelectList( (IEnumerable<SelectListItem>)ViewData["userRoles"], "Value", "Text", model.RoleId),
                  htmlAttributes: new { @class = "form-control" }
                  )
         </td>
     </tr>
 </table>

You can use the simple not flag to validate that. Example

if !@objectname

This will return true if @objectname is nil. You should not use dot operator or a nil value, else it will throw

*** NoMethodError Exception: undefined method `isNil?' for nil:NilClass

An ideal nil check would be like:

!@objectname || @objectname.nil? || @objectname.empty?

Just tell the file-input to automatically submit the form on any change:

<form action="http://example.com">_x000D_
    <input type="file" onchange="form.submit()" />_x000D_
</form>

This solution works like this:

• onchange makes the input element execute the following script, whenever the value is modified
• form references the form, that this input element is part of
• submit() causes the form to send all data to the URL, as specified in action

Advantages of this solution:

• Works without ids. It makes life easier, if you have several forms in one html page.
• Native javascript, no jQuery or similar required.
• The code is inside the html-tags. If you inspect the html, you will see it's behavior right away.

When it comes to compiling the program, I don't know if there is any difference. But as for the program itself and keeping the code as simple as possible, I personally think it depends on what you want to do. if else if else statements have their advantages, which I think are:

allow you to test a variable against specific ranges you can use functions (Standard Library or Personal) as conditionals.

(example:

`int a;
 cout<<"enter value:\n";
 cin>>a;

 if( a > 0 && a < 5)
   {
     cout<<"a is between 0, 5\n";

   }else if(a > 5 && a < 10)

     cout<<"a is between 5,10\n";

   }else{

       "a is not an integer, or is not in range 0,10\n";

However, If else if else statements can get complicated and messy (despite your best attempts) in a hurry. Switch statements tend to be clearer, cleaner, and easier to read; but can only be used to test against specific values (example:

`int a;
 cout<<"enter value:\n";
 cin>>a;

 switch(a)
 {
    case 0:
    case 1:
    case 2: 
    case 3:
    case 4:
    case 5:
        cout<<"a is between 0,5 and equals: "<<a<<"\n";
        break;
    //other case statements
    default:
        cout<<"a is not between the range or is not a good value\n"
        break;

I prefer if - else if - else statements, but it really is up to you. If you want to use functions as the conditions, or you want to test something against a range, array, or vector and/or you don't mind dealing with the complicated nesting, I would recommend using If else if else blocks. If you want to test against single values or you want a clean and easy to read block, I would recommend you use switch() case blocks.

I used it with a regular maven project, and got it solved with this plugin dependency configuration for running the xjc plugin:

Try this its worked for me

SELECT * from bookedroom
    WHERE UNIX_TIMESTAMP('2020-8-07 5:31')
        between UNIX_TIMESTAMP('2020-8-07 5:30') and
        UNIX_TIMESTAMP('2020-8-09 5:30')

You need read access, in addition to execute access, to list a directory. If you only have execute access, then you can find out the names of entries in the directory, but no other information (not even types, so you don't know which of the entries are subdirectories). This works for me:

find . -type d -exec chmod +rx {} \;

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

I usualy use a multi-culture function to parse user input, mostly because if someone is used to the numpad and is using a culture that use a comma as the decimal separator, that person will use the point of the numpad instead of a comma.

public static double GetDouble(string value, double defaultValue)
{
    double result;

    //Try parsing in the current culture
    if (!double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.CurrentCulture, out result) &&
        //Then try in US english
        !double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out result) &&
        //Then in neutral language
        !double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.InvariantCulture, out result))
    {
        result = defaultValue;
    }

    return result;

Beware though, @nikie comments are true. To my defense, I use this function in a controlled environment where I know that the culture can either be en-US, en-CA or fr-CA. I use this function because in French, we use the comma as a decimal separator, but anybody who ever worked in finance will always use the decimal separator on the numpad, but this is a point, not a comma. So even in the fr-CA culture, I need to parse number that will have a point as the decimal separator.

We make Webapps statefull by overriding HTTP stateless behaviour by using session objects.When we use session objets state is carried but we still use HTTP only.

Many people say that checked exceptions (i.e. these that you should explicitly catch or rethrow) should not be used at all. They were eliminated in C# for example, and most languages don't have them. So you can always throw a subclass of RuntimeException (unchecked exception)

However, I think checked exceptions are useful - they are used when you want to force the user of your API to think how to handle the exceptional situation (if it is recoverable). It's just that checked exceptions are overused in the Java platform, which makes people hate them.

Here's my extended view on the topic.

As for the particular questions:

1. Is the NumberFormatException consider a checked exception?
   No. NumberFormatException is unchecked (= is subclass of RuntimeException). Why? I don't know. (but there should have been a method isValidInteger(..))

2. Is RuntimeException an unchecked exception?
   Yes, exactly.

3. What should I do here?
   It depends on where this code is and what you want to happen. If it is in the UI layer - catch it and show a warning; if it's in the service layer - don't catch it at all - let it bubble. Just don't swallow the exception. If an exception occurs in most of the cases you should choose one of these:

   • log it and return
   • rethrow it (declare it to be thrown by the method)
   • construct a new exception by passing the current one in constructor

4. Now, couldn't the above code also be a checked exception? I can try to recover the situation like this? Can I?
   It could've been. But nothing stops you from catching the unchecked exception as well

5. Why do people add class Exception in the throws clause?
   Most often because people are lazy to consider what to catch and what to rethrow. Throwing Exception is a bad practice and should be avoided.

Alas, there is no single rule to let you determine when to catch, when to rethrow, when to use checked and when to use unchecked exceptions. I agree this causes much confusion and a lot of bad code. The general principle is stated by Bloch (you quoted a part of it). And the general principle is to rethrow an exception to the layer where you can handle it.

Assuming your DataSource is of type DataTable, you can just do this:

myGridView.DataSource as DataTable

Add a literal space, or a tab:

public void displayCustomerInfo() {
    System.out.println(Name + " " + Income);

    // or a tab
    System.out.println(Name + "\t" + Income);
}

Contrary to the accepted answer you do not need a custom trust manager, you need to fix your server configuration!

I hit the same problem while connecting to an Apache server with an incorrectly installed dynadot/alphassl certificate. I'm connecting using HttpsUrlConnection (Java/Android), which was throwing -

javax.net.ssl.SSLHandshakeException: 
  java.security.cert.CertPathValidatorException: 
    Trust anchor for certification path not found.

The actual problem is a server misconfiguration - test it with http://www.digicert.com/help/ or similar, and it will even tell you the solution:

"The certificate is not signed by a trusted authority (checking against Mozilla's root store). If you bought the certificate from a trusted authority, you probably just need to install one or more Intermediate certificates. Contact your certificate provider for assistance doing this for your server platform."

You can also check the certificate with openssl:

openssl s_client -debug -connect www.thedomaintocheck.com:443

You'll probably see:

Verify return code: 21 (unable to verify the first certificate)

and, earlier in the output:

depth=0 OU = Domain Control Validated, CN = www.thedomaintocheck.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 OU = Domain Control Validated, CN = www.thedomaintocheck.com
verify error:num=27:certificate not trusted
verify return:1
depth=0 OU = Domain Control Validated, CN = www.thedomaintocheck.com
verify error:num=21:unable to verify the first certificate`

The certificate chain will only contain 1 element (your certificate):

Certificate chain
 0 s:/OU=Domain Control Validated/CN=www.thedomaintocheck.com
  i:/O=AlphaSSL/CN=AlphaSSL CA - G2

... but should reference the signing authorities in a chain back to one which is trusted by Android (Verisign, GlobalSign, etc):

Certificate chain
 0 s:/OU=Domain Control Validated/CN=www.thedomaintocheck.com
   i:/O=AlphaSSL/CN=AlphaSSL CA - G2
 1 s:/O=AlphaSSL/CN=AlphaSSL CA - G2
   i:/C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA
 2 s:/C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA
   i:/C=BE/O=GlobalSign nv-sa/OU=Root CA/CN=GlobalSign Root CA

Instructions (and the intermediate certificates) for configuring your server are usually provided by the authority that issued your certificate, for example: http://www.alphassl.com/support/install-root-certificate.html

After installing the intermediate certificates provided by my certificate issuer I now have no errors when connecting using HttpsUrlConnection.

I don't see this solution anywhere and supposedly ... according to one person, the proper way to do it is with copyPagesTo(). This does work I tested it. Your mileage may vary between city and open road driving. Goo luck.

    public static bool MergePDFs(List<string> lststrInputFiles, string OutputFile, out int iPageCount, out string strError)
    {
        strError = string.Empty;

        PdfWriter pdfWriter = new PdfWriter(OutputFile);
        PdfDocument pdfDocumentOut = new PdfDocument(pdfWriter);

        PdfReader pdfReader0 = new PdfReader(lststrInputFiles[0]);
        PdfDocument pdfDocument0 = new PdfDocument(pdfReader0);
        int iFirstPdfPageCount0 = pdfDocument0.GetNumberOfPages();
        pdfDocument0.CopyPagesTo(1, iFirstPdfPageCount0, pdfDocumentOut);
        iPageCount = pdfDocumentOut.GetNumberOfPages();

        for (int ii = 1; ii < lststrInputFiles.Count; ii++)
        {
            PdfReader pdfReader1 = new PdfReader(lststrInputFiles[ii]);
            PdfDocument pdfDocument1 = new PdfDocument(pdfReader1);
            int iFirstPdfPageCount1 = pdfDocument1.GetNumberOfPages();
            iPageCount += iFirstPdfPageCount1;
            pdfDocument1.CopyPagesTo(1, iFirstPdfPageCount1, pdfDocumentOut);
            int iFirstPdfPageCount00 = pdfDocumentOut.GetNumberOfPages();
        }

        pdfDocumentOut.Close();

        return true;
    }

In this public Github repo https://github.com/boskjoett/BasicAuthWebApi you can see a simple example of a ASP.NET Core 2.2 web API with endpoints protected by Basic Authentication.

Use dir or type on the 'string' to find out what it is. I suspect that it's one of BeautifulSoup's tag objects, that prints like a string, but really isn't one. Otherwise, its inside a list and you need to convert each string separately.

In any case, why are you objecting to using Unicode? Any specific reason?

This issue is still up on keras git. I hope it gets solved as soon as possible. Until then, try downgrading your numpy version to 1.16.2. It seems to solve the problem.

!pip install numpy==1.16.1
import numpy as np

This version of numpy has the default value of allow_pickle as True.

Generally, I am using the following method:

>>> myList = [10,20,30,40,50]
>>> rmovIndxNo = 3
>>> del myList[rmovIndxNo]
>>> myList
[10, 20, 30, 50]

Try this one: https://github.com/tantau-horia/jquery-SuperCookie

Quick Usage:

create - create cookie

check - check existance

verify - verify cookie value if JSON

check_index - verify if index exists in JSON

read_values - read cookie value as string

read_JSON - read cookie value as JSON object

read_value - read value of index stored in JSON object

replace_value - replace value from a specified index stored in JSON object

remove_value - remove value and index stored in JSON object

Just use:

$.super_cookie().create("name_of_the_cookie",name_field_1:"value1",name_field_2:"value2"});
$.super_cookie().read_json("name_of_the_cookie");

I don't know is it bug or something but your labels and other UIs does not initialized automatically when you use custom cell. You should try this in your UICollectionViewController class. It worked for me.

override func viewDidLoad() {
    super.viewDidLoad()

    let nib = UINib(nibName: "<WhateverYourNibName>", bundle: nil)
    self.collectionView.registerNib(nib, forCellReuseIdentifier: "title")
}

Open preferences windows (Command key + "," on Mac):

Attach with jvisualvm from Sun Java 6 JDK. Startup flags are listed.

You could also extend the jquery framework yourself with something like:

jQuery.fn.margin = function() {
var marginTop = this.outerHeight(true) - this.outerHeight();
var marginLeft = this.outerWidth(true) - this.outerWidth();

return {
    top: marginTop,
    left: marginLeft
}};

Thereby adding a function on your jquery objects called margin(), which returns a collection like the offset function.

fx.

$("#myObject").margin().top

PowerShell (the engine) runs fine under .NET 4.0. PowerShell (the console host and the ISE) do not, simply because they were compiled against older versions of .NET. There's a registry setting that will change the .NET framework loaded systemwide, which will in turn allow PowerShell to use .NET 4.0 classes:

reg add hklm\software\microsoft\.netframework /v OnlyUseLatestCLR /t REG_DWORD /d 1
reg add hklm\software\wow6432node\microsoft\.netframework /v OnlyUseLatestCLR /t REG_DWORD /d 1

To update just the ISE to use .NET 4.0, you can change the configuration ($psHome\powershell_ise.exe.config) file to have a chunk like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <startup>
      <supportedRuntime version="v4.0.30319" />
    </startup>
</configuration>

You can build .NET 4.0 applications that call PowerShell using the PowerShell API (System.Management.Automation.PowerShell) just fine, but these steps will help get the in-the-box PowerShell hosts to work under .NET 4.0.

Remove the registry keys when you don't need them any more. These are machine-wide keys and forcibly migrate ALL applications to .NET 4.0, even applications using .net 2 and .net 3.5

In general Tight Coupling is bad in but most of the time, because it reduces flexibility and re-usability of code, it makes changes much more difficult, it impedes testability etc.

Tightly Coupled Object is an object need to know quite a bit about each other and are usually highly dependent on each other interfaces. Changing one object in a tightly coupled application often requires changes to a number of other objects, In small application we can easily identify the changes and there is less chance to miss anything. But in large applications these inter-dependencies are not always known by every programmer or chance is there to miss changes. But each set of loosely coupled objects are not dependent on others.

In short we can say, loose coupling is a design goal that seeks to reduce the interdependencies between components of a system with the goal of reducing the risk that changes in one component will require changes in any other component. Loose coupling is a much more generic concept intended to increase the flexibility of a system, make it more maintainable, and make the entire framework more 'stable'.

Coupling refers to the degree of direct knowledge that one element has of another. we can say an eg: A and B, only B change its behavior only when A change its behavior. A loosely coupled system can be easily broken down into definable elements.

Use gv$session for RAC, if you want get the total number of session across the cluster.

you add in :

TextView variableTv = (TextView) findViewById(R.id.yourText);

you set/add in You variable :

variableTv.setText("It's Text use Style Strike");

and then add .setPaintFlags in variableTv :

variableTv.setPaintFlags(variableTv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

You can also use

$('#myModal').hasClass('show');

setOpaque(false); 

CHANGED to

setOpaque(true);

Multiprogramming:- in which execution of multiple jobs by the same computer not at the same time.

Multitasking :- o/s in which more than one task are executed at the same time.

__FILE__ is the filename with extension of the file containing the code being executed.

In foo.rb, __FILE__ would be "foo.rb".

If foo.rb were in the dir /home/josh then File.dirname(__FILE__) would return /home/josh.

Go inside your phpMyAdmin directory inside XAMPP installation folder. There will be a file called config.inc.php. Inside that file, find this line:

$cfg['Servers'][$i]['password'] = '';

you must make sure that this field has your mysql root password (the one that you set).

You do not need {{}} in when conditions. What you are searching for is:

- fail: msg="unsupported version"
  when: version not in acceptable_versions

You could do:

svn revert -R .

This will not delete any new file not under version control. But you can easily write a shell script to do that like:

for file in `svn status|grep "^ *?"|sed -e 's/^ *? *//'`; do rm $file ; done

• SQL is a query language to operate on sets.

  It is more or less standardized, and used by almost all relational database management systems: SQL Server, Oracle, MySQL, PostgreSQL, DB2, Informix, etc.

• PL/SQL is a proprietary procedural language used by Oracle

• PL/pgSQL is a procedural language used by PostgreSQL

• TSQL is a proprietary procedural language used by Microsoft in SQL Server.

Procedural languages are designed to extend SQL's abilities while being able to integrate well with SQL. Several features such as local variables and string/data processing are added. These features make the language Turing-complete.

They are also used to write stored procedures: pieces of code residing on the server to manage complex business rules that are hard or impossible to manage with pure set-based operations.

And here's an example of the customizer implemented in Groovy:

https://github.com/UniconLabs/orville/blob/master/web/src/main/groovy/org/apereo/openregistry/config/TomcatSslConfiguration.groovy

Here's a very simple way. Create two files:

protect-this.php

<?php
    /* Your password */
    $password = 'MYPASS';

    if (empty($_COOKIE['password']) || $_COOKIE['password'] !== $password) {
        // Password not set or incorrect. Send to login.php.
        header('Location: login.php');
        exit;
    }
?>

login.php:

<?php
    /* Your password */
    $password = 'MYPASS';

    /* Redirects here after login */
    $redirect_after_login = 'index.php';

    /* Will not ask password again for */
    $remember_password = strtotime('+30 days'); // 30 days

    if (isset($_POST['password']) && $_POST['password'] == $password) {
        setcookie("password", $password, $remember_password);
        header('Location: ' . $redirect_after_login);
        exit;
    }
?>
<!DOCTYPE html>
<html>
<head>
    <title>Password protected</title>
</head>
<body>
    <div style="text-align:center;margin-top:50px;">
        You must enter the password to view this content.
        <form method="POST">
            <input type="text" name="password">
        </form>
    </div>
</body>
</html>

Then require protect-this.php on the TOP of the files you want to protect:

// Password protect this content
require_once('protect-this.php');

Example result:

After filling the correct password, user is taken to index.php. The password is stored for 30 days.

PS: It's not focused to be secure, but to be pratical. A hacker can brute-force this. Use it to keep normal users away. Don't use it to protect sensitive information.

If you need to convert some of them to numbers and don't know in advance which ones, some additional code will be needed. Try something like this:

b = []
for x in a:
    temp = []
    items = x.split(",")
    for item in items:
        try:
            n = int(item)
        except ValueError:
            temp.append(item)
        else:
            temp.append(n)
    b.append(temp)

This is longer than the other answers, but it's more versatile.

This one seems a bit more complete: https://github.com/dump247/angular.tree

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

Put this in your CMakeLists.txt file (change any options from OFF to ON if you want):

set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF) 
find_package(Boost 1.45.0 COMPONENTS *boost libraries here*) 

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS}) 
    add_executable(progname file1.cxx file2.cxx) 
    target_link_libraries(progname ${Boost_LIBRARIES})
endif()

Obviously you need to put the libraries you want where I put *boost libraries here*. For example, if you're using the filesystem and regex library you'd write:

find_package(Boost 1.45.0 COMPONENTS filesystem regex)

Updating Data in onStartCommand(...)

onBind(...)

onBind(...) is a better lifecycle event to initiate startForeground vs. onCreate(...) because onBind(...) passes in an Intent which may contain important data in the Bundle needed to initialize the Service. However, it is not necessary as onStartCommand(...) is called when the Service is created for the first time or called subsequent times after.

onStartCommand(...)

startForeground in onStartCommand(...) is important in order to update the Service once it has already been created.

When ContextCompat.startForegroundService(...) is called after a Service has been created onBind(...) and onCreate(...) are not called. Therefore, updated data can be passed into onStartCommand(...) via the Intent Bundle to update data in the Service.

Sample

I'm using this pattern to implement the PlayerNotificationManager in the Coinverse cryptocurrency news app.

Activity / Fragment.kt

context?.bindService(
        Intent(context, AudioService::class.java),
        serviceConnection, Context.BIND_AUTO_CREATE)
ContextCompat.startForegroundService(
        context!!,
        Intent(context, AudioService::class.java).apply {
            action = CONTENT_SELECTED_ACTION
            putExtra(CONTENT_SELECTED_KEY, contentToPlay.content.apply {
                audioUrl = uri.toString()
            })
        })

AudioService.kt

private var uri: Uri = Uri.parse("")

override fun onBind(intent: Intent?) =
        AudioServiceBinder().apply {
            player = ExoPlayerFactory.newSimpleInstance(
                    applicationContext,
                    AudioOnlyRenderersFactory(applicationContext),
                    DefaultTrackSelector())
        }

override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
    intent?.let {
        when (intent.action) {
            CONTENT_SELECTED_ACTION -> it.getParcelableExtra<Content>(CONTENT_SELECTED_KEY).also { content ->
                val intentUri = Uri.parse(content.audioUrl)
                // Checks whether to update Uri passed in Intent Bundle.
                if (!intentUri.equals(uri)) {
                    uri = intentUri
                    player?.prepare(ProgressiveMediaSource.Factory(
                            DefaultDataSourceFactory(
                                    this,
                                    Util.getUserAgent(this, getString(app_name))))
                            .createMediaSource(uri))
                    player?.playWhenReady = true
                    // Calling 'startForeground' in 'buildNotification(...)'.          
                    buildNotification(intent.getParcelableExtra(CONTENT_SELECTED_KEY))
                }
            }
        }
    }
    return super.onStartCommand(intent, flags, startId)
}

// Calling 'startForeground' in 'onNotificationStarted(...)'.
private fun buildNotification(content: Content): Unit? {
    playerNotificationManager = PlayerNotificationManager.createWithNotificationChannel(
            this,
            content.title,
            app_name,
            if (!content.audioUrl.isNullOrEmpty()) 1 else -1,
            object : PlayerNotificationManager.MediaDescriptionAdapter {
                override fun createCurrentContentIntent(player: Player?) = ...
                override fun getCurrentContentText(player: Player?) = ...
                override fun getCurrentContentTitle(player: Player?) = ...
                override fun getCurrentLargeIcon(player: Player?,
                                                 callback: PlayerNotificationManager.BitmapCallback?) = ...
            },
            object : PlayerNotificationManager.NotificationListener {
                override fun onNotificationStarted(notificationId: Int, notification: Notification) {
                    startForeground(notificationId, notification)
                }
                override fun onNotificationCancelled(notificationId: Int) {
                    stopForeground(true)
                    stopSelf()
                }
            })
    return playerNotificationManager.setPlayer(player)
}

If you are on android and using threetenbp you can use DateTimeUtils instead.

ex:

Date date = DateTimeUtils.toDate(localDateTime.atZone(ZoneId.systemDefault()).toInstant());

you can't use Date.from since it's only supported on api 26+

If you don't want anything to display before the redirect, then you will need to use some server side scripting to accomplish the task before the page is served. The page has already begun loading by the time your Javascript is executed on the client side.

If Javascript is your only option, your best best is to make your script the first .js file included in the <head> of your document.

Instead of Javascript, I recommend setting up your redirect logic in your Apache or nginx server configuration.

        Node<T> temp = this.head;
        while (temp != null)
        {
            Console.WriteLine(temp.item);
            temp = temp.next;
        }
    }

}

You can get something suitable for that purpose with:

I've decided to post a new answer, because some existing answers are outdated or incomplete.

First of all: there is nothing like JUnit XML Format Specification, simply because JUnit doesn't produce any kind of XML or HTML report.

The XML report generation itself comes from the Ant JUnit task/ Maven Surefire Plugin/ Gradle (whichever you use for running your tests). The XML report format was first introduced by Ant and later adapted by Maven (and Gradle).

If somebody just needs an official XML format then:

1. There exists a schema for a maven surefire-generated XML report and it can be found here: surefire-test-report.xsd.
2. For an ant-generated XML there is a 3rd party schema available here (but it might be slightly outdated).

Hope it will help somebody.

In case of Mac OSX,

Go to Targets -> Build Phases click + to Copy new files build phases Select product directory and drop the file there.

Clean and run the project.

Since AngularJS 1.3.4 you can use $setDirty() on fields (source). For example, for each field with error and marked required you can do the following:

angular.forEach($scope.form.$error.required, function(field) {
    field.$setDirty();
});

<div style="border-style: solid;width:13px"> 
   <input type="checkbox" name="mycheck" style="margin:0;padding:0;">
   </input> 
</div>

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

I was crazy to delete node and npm and nodejs from my Ubuntu 14.04 but with this steps you will remove it:

sudo apt-get uninstall nodejs npm node
sudo apt-get remove nodejs npm node

If you uninstall correctly and it is still there, check these links:

• Stack Overflow answer with more information
• Remove npm - Official website
• Stack Overflow answer for uninstalling if you installed via git repository
• Try purging nodejs npm and node

You can also try using find:

find / -name "node"

Although since that is likely to take a long time and return a lot of confusing false positives, you may want to search only PATH locations:

find $(echo $PATH | sed 's/:/ /g') -name "node"

It would probably be in /usr/bin/node or /usr/local/bin. After finding it, you can delete it using the correct path, eg:

sudo rm /usr/bin/node

Check that if you have a static handler in your class. If so, please be careful, cause static handler only could be initiated in thread which has a looper, the crash could be triggered in this way:

1.firstly, create the instance of class in a simple thread and catch the crash.

2.then call the field method of Class in main thread, you will get the NoClassDefFoundError.

here is the test code:

public class MyClass{
       private static  Handler mHandler = new Handler();
       public static int num = 0;
}

in your onCrete method of Main activity, add test code part:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //test code start
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                MyClass myClass = new MyClass();
            } catch (Throwable e) {
                e.printStackTrace();
            }
        }
    }).start();

    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    MyClass.num = 3;
    // end of test code
}

there is a simple way to fix it using a handlerThread to init handler:

private static Handler mHandler;
private static HandlerThread handlerThread = new HandlerThread("newthread");
static {
    handlerThread.start();
    mHandler = new Handler(handlerThread.getLooper(), mHandlerCB);
}

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

static variable

• It is a variable which belongs to the class and not to object(instance)
• Static variables are initialized only once , at the start of the execution(when the Classloader load the class for the first time) .
• These variables will be initialized first, before the initialization of any instance variables
• A single copy to be shared by all instances of the class
• A static variable can be accessed directly by the class name and doesn’t need any object

It looks like there is an extra curly bracket in the code.

function () {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        document.getElementById("content").innerHTML = xmlhttp.responseText;
    }
// extra bracket }
xmlhttp.open("GET", "data/" + id + ".html", true);
xmlhttp.send();
}

If you were trying to do what I imagine you were trying to do, then you only have to treat scope like a regular JS object.

This is what I use for an API success response for JSON data array...

function(data){

    $scope.subjects = [];

    $.each(data, function(i,subject){
        //Store array of data types
        $scope.subjects.push(subject.name);

        //Split data in to arrays
        $scope[subject.name] = subject.data;
    });
}

Now {{subjects}} will return an array of data subject names, and in my example there would be a scope attribute for {{jobs}}, {{customers}}, {{staff}}, etc. from $scope.jobs, $scope.customers, $scope.staff

public static class ErrorCode
{
    public const IDictionary<string , string > m_ErrorCodeDic;

    public static ErrorCode()
    {
      m_ErrorCodeDic = new Dictionary<string, string>()
             { {"1","User name or password problem"} };             
    }
}

Probably initialise in the constructor.

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

On Run Configuration> Android Application > App > Target > Additional Emulator Command Line Options: -http-proxy http://xx.xxx.xx.xx:8080

While the above responses provide most of the answer it is useful--even this late to the question--to provide the full answer, to wit:

Array sub-expression (see about_arrays)

Forces the value to be an array, even if a singleton or a null, e.g. $a = @(ps | where name -like 'foo')

Hash initializer (see about_hash_tables)

Initializes a hash table with key-value pairs, e.g. $HashArguments = @{ Path = "test.txt"; Destination = "test2.txt"; WhatIf = $true }

Splatting (see about_splatting)

Let's you invoke a cmdlet with parameters from an array or a hash-table rather than the more customary individually enumerated parameters, e.g. using the hash table just above, Copy-Item @HashArguments

Here strings (see about_quoting_rules)

Let's you create strings with easily embedded quotes, typically used for multi-line strings, e.g.:

$data = @"
line one
line two
something "quoted" here
"@

Because this type of question (what does 'x' notation mean in PowerShell?) is so common here on StackOverflow as well as in many reader comments, I put together a lexicon of PowerShell punctuation, just published on Simple-Talk.com. Read all about @ as well as % and # and $_ and ? and more at The Complete Guide to PowerShell Punctuation. Attached to the article is this wallchart that gives you everything on a single sheet:

If you pass only vectors to cbind() it creates a matrix, not a dataframe. Read ?data.frame.

I would say a lot of people with Web experience prior to angular, are use to deploying their web artifacts inside a war (i.e. jquery and html inside a Java/Spring project). I ended up doing this to get around CORS issue, after attempting to keep my angular and REST projects separate.

My solution was to move all angular (4) contents, generated with CLI, from my-app to MyJavaApplication/angular. Then I modifed my Maven build to use maven-resources-plugin to move the contents from /angular/dist to the root of my distribution (i.e. $project.build.directory}/MyJavaApplication). Angular loads resources from root of the war by default.

When I started to add routing to my angular project, I further modifed maven build to copy index.html from /dist to WEB-INF/app. And, added a Java controller that redirects all server side rest calls to index.

This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.

Since you know how many types of layout you would have - it's possible to use those methods.

getViewTypeCount() - this methods returns information how many types of rows do you have in your list

getItemViewType(int position) - returns information which layout type you should use based on position

Then you inflate layout only if it's null and determine type using getItemViewType.

Look at this tutorial for further information.

To achieve some optimizations in structure that you've described in comment I would suggest:

• Storing views in object called ViewHolder. It would increase speed because you won't have to call findViewById() every time in getView method. See List14 in API demos.
• Create one generic layout that will conform all combinations of properties and hide some elements if current position doesn't have it.

I hope that will help you. If you could provide some XML stub with your data structure and information how exactly you want to map it into row, I would be able to give you more precise advise. By pixel.

They are both quite similar in solving for the solution, but as others have said, one (Logistic Regression) is for predicting a category "fit" (Y/N or 1/0), and the other (Linear Regression) is for predicting a value.

So if you want to predict if you have cancer Y/N (or a probability) - use logistic. If you want to know how many years you will live to - use Linear Regression !

In general it would be something like this:

if(test != "A" && test != "B")

You should probably read up on JavaScript logical operators.

This is what I do:

First checkout your branch (for my case master branch):

git checkout master

Then reset to remote HEAD^ (it'll remove all your local changes), force clean and pull:

git reset HEAD^ --hard && git clean -df && git pull

As pointed out in answers above

my_string.strip()

will remove all the leading and trailing whitespace characters such as \n, \r, \t, \f, space .

For more flexibility use the following

• Removes only leading whitespace chars: my_string.lstrip()
• Removes only trailing whitespace chars: my_string.rstrip()
• Removes specific whitespace chars: my_string.strip('\n') or my_string.lstrip('\n\r') or my_string.rstrip('\n\t') and so on.

More details are available in the docs.

Getting both stdout and stderr (and also writing to stdin, not shown here) is easy peasy with my pstreams header, which defines iostream classes that work like popen:

#include <pstream.h>
#include <string>
#include <iostream>

int main()
{
  // run a process and create a streambuf that reads its stdout and stderr
  redi::ipstream proc("./some_command", redi::pstreams::pstdout | redi::pstreams::pstderr);
  std::string line;
  // read child's stdout
  while (std::getline(proc.out(), line))
    std::cout << "stdout: " << line << '\n';
  # if reading stdout stopped at EOF then reset the state:
  if (proc.eof() && proc.fail())
    proc.clear();
  // read child's stderr
  while (std::getline(proc.err(), line))
    std::cout << "stderr: " << line << '\n';
} 

The long must be at least the same size as an int, and possibly, but not necessarily, longer.

On common 32-bit systems, both int and long are 4-bytes/32-bits, and this is valid according to the C++ spec.

On other systems, both int and long long may be a different size. I used to work on a platform where int was 2-bytes, and long was 4-bytes.

list.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

Great! The solution given above worked for me. Had the same problem with a GET call.

 method: 'GET',
 data: '',
 headers: {
        "Content-Type": "application/json"
 }

In jQuery, the $ sign is just an alias to jQuery(), then an alias to a function.

This page reports:

Basic syntax is: $(selector).action()

• A dollar sign to define jQuery
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

Further to the Mark Parnell's answer, a quick-and-dirty way of getting around this is to put the manifest plist into Dropbox, and then using the Dropbox web interface to get a direct https link to it ('Share link' -> 'Get link' -> 'Download').

The actual ipa can remain wherever you always served it from. You'll need to URL-encode the plist's URL before inserting it into the itms-servivces URL's query (although just replacing any &s with %3D might work).

One downside is that the install dialog will now read "dl.dropbox.com wants to install [whatever]".

You can do this with the win32 class in the Microsoft namespace

using Microsoft.Win32;

using (RegistryKey key = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true))
 {
            key.SetValue("aldwin", "\"" + Application.ExecutablePath + "\"");
 }

I tried many ways but this works.

Sample code is availalbe in DBCC SHRINKFILE

USE DBName;  
GO  
-- Truncate the log by changing the database recovery model to SIMPLE.  
ALTER DATABASE DBName  
SET RECOVERY SIMPLE;  
GO  
-- Shrink the truncated log file to 1 MB.  
DBCC SHRINKFILE (DBName_log, 1);  --File name SELECT * FROM sys.database_files; query to get the file name
GO  
-- Reset the database recovery model.  
ALTER DATABASE DBName  
SET RECOVERY FULL;  
GO

Different ways to replace NULL in sql server

Replacing NULL value using:

1. ISNULL() function

2. COALESCE() function

3. CASE Statement

SELECT Name as EmployeeName, ISNULL(Bonus,0) as EmployeeBonus from tblEmployee

SELECT Name as EmployeeName, COALESCE(Bonus, 0) as EmployeeBonus 
FROM tblEmployee

SELECT Name as EmployeeName, CASE WHEN Bonus IS NULL THEN 0 
ELSE Bonus  END as EmployeeBonus 
FROM  tblEmployee

The implicit make rule for compiling a C program is

%.o:%.c
    $(CC) $(CPPFLAGS) $(CFLAGS) -c -o $@ $<

where the $() syntax expands the variables. As both CPPFLAGS and CFLAGS are used in the compiler call, which you use to define include paths is a matter of personal taste. For instance if foo.c is a file in the current directory

make foo.o CPPFLAGS="-I/usr/include"
make foo.o CFLAGS="-I/usr/include"

will both call your compiler in exactly the same way, namely

gcc -I/usr/include -c -o foo.o foo.c

The difference between the two comes into play when you have multiple languages which need the same include path, for instance if you have bar.cpp then try

make bar.o CPPFLAGS="-I/usr/include"
make bar.o CFLAGS="-I/usr/include"

then the compilations will be

g++ -I/usr/include -c -o bar.o bar.cpp
g++ -c -o bar.o bar.cpp

as the C++ implicit rule also uses the CPPFLAGS variable.

This difference gives you a good guide for which to use - if you want the flag to be used for all languages put it in CPPFLAGS, if it's for a specific language put it in CFLAGS, CXXFLAGS etc. Examples of the latter type include standard compliance or warning flags - you wouldn't want to pass -std=c99 to your C++ compiler!

You might then end up with something like this in your makefile

CPPFLAGS=-I/usr/include
CFLAGS=-std=c99
CXXFLAGS=-Weffc++

To get the route segments:

import { ActivatedRoute, UrlSegment } from '@angular/router';

constructor( route: ActivatedRoute) {}

getRoutes() { const segments: UrlSegment[] = this.route.snapshot.url; }

As stated in other answers, https is now required to make requests to Maven Central, while older versions of Maven use http.

If you don't want to/cannot upgrade to Maven 3.2.3+, you can do a workaround by adding the following code into your MAVEN_HOME\conf\settings.xml into the <profiles> section:

<profile>
    <id>maven-https</id>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
    <repositories>
        <repository>
            <id>central</id>
            <url>https://repo1.maven.org/maven2</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>central</id>
            <url>https://repo1.maven.org/maven2</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </pluginRepository>
    </pluginRepositories> 
</profile>

This will be always an active setting unless you disable/override it in your POM when needed.

In the windows when we open jupyter notebook in command prompt we can see the instructions in first 10 lines in that there is one instruction- "to open notebook, open this file in browser file://C:/Users/{username}/appdata/roaming/jupyetr/runtime/nbserver-xywz-open.html " , open this html with browser of your choice.

I had this error coming up between 2 Linux boxes. Easily solved by installing RSYNC on the remote box as well as the local one.

I know this is old, but I was able to accomplish this with

viewToUse.setImageResource(0);

Doesn't seem like it should work, but I tried it on a whim, and it worked perfectly.

I'd suggest a different approach to this question. Maybe it's not the most efficient one, but I think it's the easiest to apply and requires very little code. Writing the next code in your first activity (log in activity, in my case) won't let the user go back to previously launched activities after logging out.

@Override
public void onBackPressed() {
    // disable going back to the MainActivity
    moveTaskToBack(true);
}

I'm assuming that LoginActivity is finished just after the user logs in, so that he can't go back to it later by pressing the back button. Instead, the user must press a log out button inside the app in order to log out properly. What this log out button would implement is a simple intent as follows:

Intent intent = new Intent(this, LoginActivity.class);
startActivity(intent);
finish();

All suggestions are welcome.

The syntax:

   ALTER TABLE `table1` CHANGE `itemId` `itemId` INT( 11 ) NOT NULL AUTO_INCREMENT 

But the table needs a defined key (ex primary key on itemId).

Put your wamp server online

and then go to control panel > system and security > windows firewall and turn windows firewall off

now you can access your wamp server from another computer over local network by the network IP of computer which have wamp server installed like http://192.168.2.34/mysite

Edited Java 8 Solution:

final Drawable drawable = 
    Optional.ofNullable(Common.getDrawableFromUrl(this, product.getMapPath()))
        .orElseGet(() -> getRandomDrawable());

You can declare drawable final in this case.

As Chasmo pointed out, Android doesn't support Java 8 at the moment. So this solution is only possible in other contexts.

You can also achieve other way using button tag

According new html5 attribute you also can add a form attribute like

<form id="formId">
    <input type="text" name="fname">
</form>

<button id="myButton" form='#formId'>My Awesome Button</button>

So the button will be attached to the form.

This should work with the validate() plugin of jQuery like :

var validator = $( "#formId" ).validate();
validator.element( "#myButton" );

It's working too with input tag

It's important that your THEAD not be empty in table.As dataTable requires you to specify the number of columns of the expected data . As per your data it should be

            <th>Subscriber ID</th>
            <th>Install Location</th>
            <th>Subscriber Name</th>

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

I created a dummy variable for every state using this code.

def create_dummy_column(series, f):
    return series.apply(f)

for el in df.area_title.unique():
    col_name = el.split()[0] + "_dummy"
    f = lambda x: int(x==el)
    df[col_name] = create_dummy_column(df.area_title, f)
df.head()

More generally, I would just use .apply and pass it an anonymous function with the inequality that defines your category.

(Thank you to @prpl.mnky.dshwshr for the .unique() insight)

Your TextView Attributes need to be something like,

<TextView ... 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical|right" ../>

Now, Description why these need to be done,

 android:layout_width="match_parent"
 android:layout_height="match_parent"

Makes your TextView to match_parent or fill_parent if You don't want to be it like, match_parent you have to give some specified values to layout_height so it get space for vertical center gravity. android:layout_width="match_parent" necessary because it align your TextView in Right side so you can recognize respect to Parent Layout of TextView.

Now, its about android:gravity which makes the content of Your TextView alignment. android:layout_gravity makes alignment of TextView respected to its Parent Layout.

Update:

As below comment says use fill_parent instead of match_parent. (Problem in some device.)

I hope it still not too late to share my solution. Before that, you can follow the tutorial as stated in Android Developer documentation. To achieve this, you need to use Cluster Manager with defaultRenderer.

1. Create an object that implements ClusterItem

   public class SampleJob implements ClusterItem {
   
   private double latitude;
   private double longitude;
   
   //Create constructor, getter and setter here
   
   @Override
   public LatLng getPosition() {
       return new LatLng(latitude, longitude);
   }
   

2. Create a default renderer class. This is the class that do all the job (inflating custom marker/cluster with your own style). I am using Universal image loader to do the downloading and caching the image.

   public class JobRenderer extends DefaultClusterRenderer< SampleJob > {
   
   private final IconGenerator iconGenerator;
   private final IconGenerator clusterIconGenerator;
   private final ImageView imageView;
   private final ImageView clusterImageView;
   private final int markerWidth;
   private final int markerHeight;
   private final String TAG = "ClusterRenderer";
   private DisplayImageOptions options;
   
   
   public JobRenderer(Context context, GoogleMap map, ClusterManager<SampleJob> clusterManager) {
       super(context, map, clusterManager);
   
       // initialize cluster icon generator
       clusterIconGenerator = new IconGenerator(context.getApplicationContext());
       View clusterView = LayoutInflater.from(context).inflate(R.layout.multi_profile, null);
       clusterIconGenerator.setContentView(clusterView);
       clusterImageView = (ImageView) clusterView.findViewById(R.id.image);
   
       // initialize cluster item icon generator
       iconGenerator = new IconGenerator(context.getApplicationContext());
       imageView = new ImageView(context.getApplicationContext());
       markerWidth = (int) context.getResources().getDimension(R.dimen.custom_profile_image);
       markerHeight = (int) context.getResources().getDimension(R.dimen.custom_profile_image);
       imageView.setLayoutParams(new ViewGroup.LayoutParams(markerWidth, markerHeight));
       int padding = (int) context.getResources().getDimension(R.dimen.custom_profile_padding);
       imageView.setPadding(padding, padding, padding, padding);
       iconGenerator.setContentView(imageView);
   
       options = new DisplayImageOptions.Builder()
               .showImageOnLoading(R.drawable.circle_icon_logo)
               .showImageForEmptyUri(R.drawable.circle_icon_logo)
               .showImageOnFail(R.drawable.circle_icon_logo)
               .cacheInMemory(false)
               .cacheOnDisk(true)
               .considerExifParams(true)
               .bitmapConfig(Bitmap.Config.RGB_565)
               .build();
   }
   
   @Override
   protected void onBeforeClusterItemRendered(SampleJob job, MarkerOptions markerOptions) {
   
   
       ImageLoader.getInstance().displayImage(job.getJobImageURL(), imageView, options);
       Bitmap icon = iconGenerator.makeIcon(job.getName());
       markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon)).title(job.getName());
   
   
   }
   
   @Override
   protected void onBeforeClusterRendered(Cluster<SampleJob> cluster, MarkerOptions markerOptions) {
   
       Iterator<Job> iterator = cluster.getItems().iterator();
       ImageLoader.getInstance().displayImage(iterator.next().getJobImageURL(), clusterImageView, options);
       Bitmap icon = clusterIconGenerator.makeIcon(iterator.next().getName());
       markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));
   }
   
   @Override
   protected boolean shouldRenderAsCluster(Cluster cluster) {
       return cluster.getSize() > 1;
   }
   

3. Apply cluster manager in your activity/fragment class.

   public class SampleActivity extends AppCompatActivity implements OnMapReadyCallback {
   
   private ClusterManager<SampleJob> mClusterManager;
   private GoogleMap mMap;
   private ArrayList<SampleJob> jobs = new ArrayList<SampleJob>();
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_landing);
   
       SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
               .findFragmentById(R.id.map);
       mapFragment.getMapAsync(this);
   }
   
   
   @Override
   public void onMapReady(GoogleMap googleMap) {
       mMap = googleMap;
       mMap.getUiSettings().setMapToolbarEnabled(true);
       mClusterManager = new ClusterManager<SampleJob>(this, mMap);
       mClusterManager.setRenderer(new JobRenderer(this, mMap, mClusterManager));
       mMap.setOnCameraChangeListener(mClusterManager);
       mMap.setOnMarkerClickListener(mClusterManager);
   
       //Assume that we already have arraylist of jobs
   
   
       for(final SampleJob job: jobs){
           mClusterManager.addItem(job);
       }
       mClusterManager.cluster();
   }
   

4. Result

No, its easy to do this. In Xcode, set the Active Configuration to Release. Change the device from Simulator to Device - whatever SDK. If you want to directly export to your iPhone, connect it to your computer. Press Build and Go. If your iPhone is not connected to your computer, a message will come up saying that your iPhone is not connected.

If this applies to you: (iPhone was not connected)

Go to your projects folder and then to the build folder inside. Go to the Release-iphoneos folder and take the app inside, drag and drop on iTunes icon. When you sync your iTouch device, it will copy it to your device. It will also show up in iTunes as a application for the iPhone.

Hope this helps!

P.S.: If it says something about a certificate not being valid, just click on the project in Xcode, the little project icon in the file stack to the left, and press Apple+I, or do Get Info from the menu bar. Click on Build at the top. Under Code Signing, change Code Signing Identity - Any iPhone OS Device to be Don't Sign.

I had to add a Return-Path header in emails send by a Redmine instance. I agree with greatwolf only the sender can determine a correct (non default) Return-Path. The case is the following : E-mails are send with the default email address : [email protected] But we want that the real user initiating the action receives the bounce emails, because he will be the one knowing how to fix wrong recipients emails (and not the application adminstrators that have other cats to whip :-) ). We use this and it works perfectly well with exim on the application server and zimbra as the final company mail server.

Use curl;

curl http://127.0.0.1:8000 -o index.html

If you don't really need a true .Net PDF library, there are numerous free HTML to PDF tools, many of which can run from a command-line.

One solution would be to pick one of those and then write a thin wrapper around that in C#. E.g., as done in this tutorial.

You just need

.parent-div { text-align: center }

I've tried most of the top options but it seems that I had something wrong with my environment setup so they didn't help. What solved the issue for me was to re-install jdk1.8.0_201 and jre1.8.0_201 and this solved the error for me. Hope that helps someone.

Will the username and password be automatically SSL encrypted? Is the same true for GETs and POSTs

Yes, yes yes.

The entire communication (save for the DNS lookup if the IP for the hostname isn't already cached) is encrypted when SSL is in use.

SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS 
   (SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)

or

SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN 
    (SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)

or

SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B 
    ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL

Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

These are the steps I took (I'm on Linux).

• Switched to Software rendering (works but is too slow)
• Tried running on commanline and an error displayed.
• Forced emulator to use the system graphic drivers.

First, as @jlars62 suggested, I tried using Switching the Graphics to "Software" and this DID work. However, the performance is far to slow so I dug a little deeper.

Then I tried running the device from the console, as @CaptainCrunch suggestion. (My device was created in Android Studio; emulator in the Sdk may be in a different place on your system)

$ ~/Android/Sdk/emulator/emulator -avd Nexus_6_Edited_768Mb_API_23

For me this produced the following error:

libGL error: unable to load driver: i965_dri.so 
libGL error: driver
pointer missing libGL error: failed to load driver: i965 
...

Which I tracked down (on ArchLinux) to mean it's using the wrong graphic drivers (Android Sdk comes with it's own). You can force the system ones on the commandline with -use-system-libs:

$ ~/Android/Sdk/emulator/emulator -avd Nexus_6_Edited_768Mb_API_23 -use-system-libs

To force Android Studio to do this you can intercept the call to "emulator" like so (See Mike42) :

$ cd ~/Android/Sdk/tools/
$ mv emulator emulator.0
$ touch emulator
$ chmod +x emulator

In the new emulator file add this:

#!/bin/sh
set -ex
$0.0 $@ -use-system-libs

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

There is a new API called URLSearchParams in browsers which allow you to extract and change the values of the query string.

Currently, it seems to be supported in Firefox 44+, Chrome 49+ and Opera 36+.

Initialize/Input

To get started, create a new URLSearchParams object. For current implementations, you need to remove the "?" at the beginning of the query string, using slice(1) on the querystring, as Jake Archibald suggests:

var params = new URLSearchParams(window.location.search.slice(1)); // myParam=12

In later implementations, you should be able to use it without slice:

var params = new URLSearchParams(window.location.search); // myParam=12

Get

You can get params from it via the .get method:

params.get('myParam'); // 12

Set

Params can be changed using .set:

params.set('myParam', 'newValue');

Output

And if the current querystring is needed again, the .toString method provides it:

params.toString(); // myParam=newValue

There are a host of other methods in this API.

Polyfill

As browser support is still pretty thin, there is a small polyfill by Andrea Giammarchi (<3kB).

df.tail(1).index 

seems the most readable

This data is JSON! You can deserialize it using the built-in json module if you're on Python 2.6+, otherwise you can use the excellent third-party simplejson module.

import json    # or `import simplejson as json` if on Python < 2.6

json_string = u'{ "id":"123456789", ... }'
obj = json.loads(json_string)    # obj now contains a dict of the data

<?php
$cal1= $_GET['cal1'];
$cal2= $_GET['cal2'];
$symbol =$_GET['symbol'];


if($symbol == '+')
{
    $add = $cal1 + $cal2;
    echo "Addition is:".$add;
}

else if($symbol == '-')
{
    $subs = $cal1 - $cal2;
    echo "Substraction is:".$subs;
}

 else if($symbol == '*')
{
    $mul = $cal1 * $cal2;
    echo "Multiply is:".$mul;
}

else if($symbol == '/')
{
    $div = $cal1 / $cal2;
    echo "Division is:".$div;
}

  else
{

    echo "Oops ,something wrong in your code son";
}

With Microsoft Sql Server:

--
-- Create test case
--
DECLARE @myDateTime DATETIME
SET @myDateTime = '2008-05-03'

--
-- Convert string
--
SELECT LEFT(CONVERT(VARCHAR, @myDateTime, 120), 10)

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

I wanted to use an xml control file based on a class for my VB.net desktop WPF application. The above code to do this all in one is excellent and set me in the right direction. In case anyone is searching for a VB.net solution here is the class I built:

Imports System.IO
Imports System.Xml.Serialization

Public Class XControl

Private _person_ID As Integer
Private _person_UID As Guid

'load from file
Public Function XCRead(filename As String) As XControl
    Using sr As StreamReader = New StreamReader(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        Return CType(xmls.Deserialize(sr), XControl)
    End Using
End Function

'save to file
Public Sub XCSave(filename As String)
    Using sw As StreamWriter = New StreamWriter(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        xmls.Serialize(sw, Me)
    End Using
End Sub

'all the get/set is below here

Public Property Person_ID() As Integer
    Get
        Return _person_ID
    End Get
    Set(value As Integer)
        _person_ID = value
    End Set
End Property

Public Property Person_UID As Guid
    Get
        Return _person_UID
    End Get
    Set(value As Guid)
        _person_UID = value
    End Set
End Property

End Class

You can also cross reference repos:

githubuser/repository#xxx

xxx being the issue number

this solution work only .if your want to ignore this Warning

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:ignore="GoogleAppIndexingWarning"
    package="com.example.saloononlinesolution">

This is based on another answer, but is just reformated:

Assuming you mean you want the non-numbers stripped out, you should be able to use something like:

'
' Skips all characters in the input string except digits
'
Function GetDigits(ByVal s As String) As String
    Dim char As String
    Dim i As Integer
    GetDigits = ""
    For i = 1 To Len(s)
        char = Mid(s, i, 1)
        If char >= "0" And char <= "9" Then
            GetDigits = GetDigits + char
        End If
    Next i
End Function

Calling this with:

Dim myStr as String
myStr = GetDigits("3d1fgd4g1dg5d9gdg")
Call MsgBox(myStr)

will give you a dialog box containing:

314159

and those first two lines show how you can store it into an arbitrary string variable, to do with as you wish.

Just for completeness: You can pass slice a vector of indices:

df %>% arrange(stopSequence) %>% group_by(id) %>% slice(c(1,n()))

which gives

  id stopId stopSequence
1  1      a            1
2  1      c            3
3  2      b            1
4  2      c            4
5  3      b            1
6  3      a            3

Use hasClass('in'). It will return true if modal is in OPEN state.

E.g:

if($('.modal').hasClass('in')){
   //Do something here
}

<meta http-equiv="refresh" content="3;url=http://www.google.com/" />

DataTable dtAll = new DataTable();
DataTable dt= new DataTable();
foreach (int id in lst)
{
    dt.Merge(GetDataTableByID(id)); // Get Data Methode return DataTable
}
dtAll = dt;

You're probably not actually signing the release build of the APK via the signing wizard. You can either build the release APK from the command line with the command:

./gradlew assembleRelease

or you can choose the release variant from the Build Variants view and build it from the GUI:

subprocess.check_output() returns bytes.

so you need to convert '\n' to bytes as well:

 f.write (plaintext + b'\n')

hope this helps

All the methods and variables in Color are static. You can not instantiate a Color object.

Official Color Docs

The Color class defines methods for creating and converting color ints.

Colors are represented as packed ints, made up of 4 bytes: alpha, red, green, blue.

The values are unpremultiplied, meaning any transparency is stored solely in the alpha component, and not in the color components.

The components are stored as follows (alpha << 24) | (red << 16) | (green << 8) | blue.

Each component ranges between 0..255 with 0 meaning no contribution for that component, and 255 meaning 100% contribution.

Thus opaque-black would be 0xFF000000 (100% opaque but no contributions from red, green, or blue), and opaque-white would be 0xFFFFFFFF

Just ran into this issue on a current LG phone on a windows computer. Everything from developer options was enabled correctly, but wasn't able to see the device through ABD. Needed install drivers which I was able to do from the phone.

After connecting through USB and allowing the connection, I tapped the USB connection type notification and on the screen where you select the type of USB connection (MTP, PTP, etc..) I tapped the three dot icon in the top right hand corner of the screen and selected to install the PC drivers. After installing the drivers on my PC I was able to connect through ABD to debug.

There's a slightly modified solution that does not require additional interfaces.

As specificed in the documented functionality, the Impl suffix allows us to have such clean solution:

• Define in you regular @Repository interface, say MyEntityRepository the custom methods (in addition to your Spring Data methods)
• Create a class MyEntityRepositoryImpl (the Impl suffix is the magic) anywhere (doesn't even need to be in the same package) that implements the custom methods only and annotate such class with @Component** (@Repository will not work).
  • This class can even inject MyEntityRepository via @Autowired for use in the custom methods.

Example:

Entity class (for completeness):

package myapp.domain.myentity;
@Entity
public class MyEntity {
    @Id     private Long id;
    @Column private String comment;
}

Repository interface:

package myapp.domain.myentity;

@Repository
public interface MyEntityRepository extends JpaRepository<MyEntity, Long> {

    // EXAMPLE SPRING DATA METHOD
    List<MyEntity> findByCommentEndsWith(String x);

    List<MyEntity> doSomeHql(Long id);   // custom method, code at *Impl class below

    List<MyEntity> useTheRepo(Long id);  // custom method, code at *Impl class below

}

Custom methods implementation bean:

package myapp.infrastructure.myentity;

@Component // Must be @Component !!
public class MyEntityRepositoryImpl { // must have the exact repo name + Impl !!

    @PersistenceContext
    private EntityManager entityManager;

    @Autowired
    private MyEntityRepository myEntityRepository;

    @SuppressWarnings("unused")
    public List<MyEntity> doSomeHql(Long id) {
        String hql = "SELECT eFROM MyEntity e WHERE e.id = :id";
        TypedQuery<MyEntity> query = entityManager.createQuery(hql, MyEntity.class);
        query.setParameter("id", id);
        return query.getResultList();
    }

    @SuppressWarnings("unused")
    public List<MyEntity> useTheRepo(Long id) {
        List<MyEntity> es = doSomeHql(id);
        es.addAll(myEntityRepository.findByCommentEndsWith("DO"));
        es.add(myEntityRepository.findById(2L).get());
        return es;
    }

}

Usage:

// You just autowire the the MyEntityRepository as usual
// (the Impl class is just impl detail, the clients don't even know about it)
@Service
public class SomeService {
    @Autowired
    private MyEntityRepository myEntityRepository;

    public void someMethod(String x, long y) {
        // call any method as usual
        myEntityRepository.findByCommentEndsWith(x);
        myEntityRepository.doSomeHql(y);
    }
}

And that's all, no need for any interfaces other than the Spring Data repo one you already have.

The only possible drawbacks I identified are:

• The custom methods in the Impl class are marked as unused by the compiler, thus the @SuppressWarnings("unused") suggestion.
• You have a limit of one Impl class. (Whereas in the regular fragment interfaces implementation the docs suggest you could have many.)
• If you place the Impl class at a different package and your test uses only @DataJpaTest, you have to add @ComponentScan("package.of.the.impl.clazz") to your test, so Spring loads it.

Add following attribute to the element you want to have dotted line.

style="border-bottom: 1px dotted #ff0000;"

The error is because fName is included in the SELECT list, but is not included in a GROUP BY clause and is not part of an aggregate function (Count(), Min(), Max(), Sum(), etc.)

You can fix that problem by including fName in a GROUP BY. But then you will face the same issue with surname. So put both in the GROUP BY:

SELECT
    fName,
    surname,
    Count(*) AS num_rows
FROM
    author
    INNER JOIN book
    ON author.aID = book.authorID;
GROUP BY
    fName,
    surname

Note I used Count(*) where you wanted SUM(orders.quantity). However, orders isn't included in the FROM section of your query, so you must include it before you can Sum() one of its fields.

If you have Access available, build the query in the query designer. It can help you understand what features are possible and apply the correct Access SQL syntax.

As well as escaping quotes with backslashes, also see SO question 2911073 which explains how you could alternatively use double-quoting in a @-prefixed string:

string msg = @"I want to learn ""c#""";

You need "src/Hankees.txt"

Your file is in the source folder which is not counted as the working directory.\

Or you can move the file up to the root directory of your project and just use "Hankees.txt"

You can try something like below

$($.parseHTML(<<table html string variable here>>)).find("td:contains('<<some text to find>>')").first().prev().text();

There have been many other great posts, however I'd like to say that theoretically you should be able to create a REAL progress bar control:

1. Use CreateWindowEx() to create the progress bar

A C++ example:

hwndPB = CreateWindowEx(0, PROGRESS_CLASS, (LPTSTR) NULL, WS_CHILD | WS_VISIBLE, rcClient.left,rcClient.bottom - cyVScroll,rcClient.right, cyVScroll,hwndParent, (HMENU) 0, g_hinst, NULL);

hwndParent Should be set to the parent window. For that one could use the status bar, or a custom form! Here's the window structure of Excel found from Spy++:

This should therefore be relatively simple using FindWindowEx() function.

hwndParent = FindWindowEx(Application.hwnd,,"MsoCommandBar","Status Bar")

After the progress bar has been created you must use SendMessage() to interact with the progress bar:

Function MAKELPARAM(ByVal loWord As Integer, ByVal hiWord As Integer)
    Dim lparam As Long
    MAKELPARAM = loWord Or (&H10000 * hiWord)
End Function

SendMessage(hwndPB, PBM_SETRANGE, 0, MAKELPARAM(0, 100))
SendMessage(hwndPB, PBM_SETSTEP, 1, 0)
For i = 1 to 100
    SendMessage(hwndPB, PBM_STEPIT, 0, 0) 
Next
DestroyWindow(hwndPB)

I'm not sure how practical this solution is, but it might look somewhat more 'official' than other methods stated here.

This works for me

select * from stuff

update stuff
set TYPE1 = TYPE2
where TYPE1 is null;

update stuff
set TYPE1 = TYPE2
where TYPE1 ='Blank';

select * from stuff

Additionally you can use an app like AutoStart if you dont want to modify the code, to launch an android application at startup: AutoStart - No root

Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.

Kiss Jquery UI goodbye and a lightbox hello. You can get it here.

man you can use the basic Bootstrap Datepicker this way:

        $('#pickyDate').datepicker({
            format: "dd/mm/yyyy"
        });
    });
</script>

and inside body:

<body>
<div id="testDIV">
    <div class="container">
        <div class="hero-unit">

        </div>
    </div>
</div>

datepicker.css and bootstrap-datepicker.js you can download from here on the Download button below "About" on the left side. Hope this help someone, greetings.

Wont the below basic approach doesn't suffice your requirements?

HTML Code having a div

<div id="mydiv" onscroll='myMethod();'>

JS will have below code

function myMethod(){ alert(1); }

I just want to add that if you want to somehow store the encrypted byte array as String and then retrieve it and decrypt it (often for obfuscation of database values) you can use this approach:

import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
public class StrongAES 
{
    public void run() 
    {
        try 
        {
            String text = "Hello World";
            String key = "Bar12345Bar12345"; // 128 bit key
            // Create key and cipher
            Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
            Cipher cipher = Cipher.getInstance("AES");
            // encrypt the text
            cipher.init(Cipher.ENCRYPT_MODE, aesKey);
            byte[] encrypted = cipher.doFinal(text.getBytes());

            StringBuilder sb = new StringBuilder();
            for (byte b: encrypted) {
                sb.append((char)b);
            }

            // the encrypted String
            String enc = sb.toString();
            System.out.println("encrypted:" + enc);

            // now convert the string to byte array
            // for decryption
            byte[] bb = new byte[enc.length()];
            for (int i=0; i<enc.length(); i++) {
                bb[i] = (byte) enc.charAt(i);
            }

            // decrypt the text
            cipher.init(Cipher.DECRYPT_MODE, aesKey);
            String decrypted = new String(cipher.doFinal(bb));
            System.err.println("decrypted:" + decrypted);

        }
        catch(Exception e) 
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) 
    {
        StrongAES app = new StrongAES();
        app.run();
    }
}

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

you should never do so... and I think trying it in latest browsers is useless(from what I know)... all latest browsers on the other hand, will not allow this...

some other links that you can go through, to find a workaround like getting the value serverside, but not in clientside(javascript)

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

Okay. You only need to use 'flatMap' when you're facing nested Optionals. Here's the example.

public class Person {

    private Optional<Car> optionalCar;

    public Optional<Car> getOptionalCar() {
        return optionalCar;
    }
}

public class Car {

    private Optional<Insurance> optionalInsurance;

    public Optional<Insurance> getOptionalInsurance() {
        return optionalInsurance;
    }
}

public class Insurance {

    private String name;

    public String getName() {
        return name;
    }

}

public class Test {

    // map cannot deal with nested Optionals
    public Optional<String> getCarInsuranceName(Person person) {
        return person.getOptionalCar()
                .map(Car::getOptionalInsurance) // ? leads to a Optional<Optional<Insurance>
                .map(Insurance::getName);       // ?
    }

}

Like Stream, Optional#map will return a value wrapped by a Optional. That's why we get a nested Optional -- Optional<Optional<Insurance>. And at ?, we want to map it as an Insurance instance, that's how the tragedy happened. The root is nested Optionals. If we can get the core value regardless the shells, we'll get it done. That's what flatMap does.

public Optional<String> getCarInsuranceName(Person person) {
    return person.getOptionalCar()
                 .flatMap(Car::getOptionalInsurance)
                 .map(Insurance::getName);
}

In the end, I stronly recommed the Java 8 In Action to you if you'd like to study Java8 Systematicly.

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

This may also be achieved using matplotlib.pyplot.quiver, as noted in the linked answer;

plt.quiver([0, 0, 0], [0, 0, 0], [1, -2, 4], [1, 2, -7], angles='xy', scale_units='xy', scale=1)
plt.xlim(-10, 10)
plt.ylim(-10, 10)
plt.show()

Why not try IS?

$('selector').is(':checked') /* result true or false */

Look a FAQ: jQuery .is() enjoin us ;-)

exit() will kill the Kernel if you're in Jupyter Notebook so it's not a good idea. raise command will stop the program.

The tuple function takes only one argument which has to be an iterable

tuple([iterable])

Return a tuple whose items are the same and in the same order as iterable‘s items.

Try making 3,4 an iterable by either using [3,4] (a list) or (3,4) (a tuple)

For example

a_list.append(tuple((3, 4)))

will work

Adding strings concatenates them:

> "1" + "1"
"11"

You have to parse them into numbers first:

/* parseFloat is used here. 
 * Because of it's not known that 
 * whether the number has fractional places.
 */

var a = parseFloat($('#a').val()),
    b = parseFloat($('#b').val());

Also, you have to get the values from inside of the click handler:

$("submit").on("click", function() {
   var a = parseInt($('#a').val(), 10),
       b = parseInt($('#b').val(), 10);
});

Otherwise, you're using the values of the textboxes from when the page loads.

Well, a for or while loop differs from a do while loop. A do while executes the statements atleast once, even if the condition turns out to be false.

The for loop you specified is absolutely correct.

Although i will do all the loops for you once again.

int sum = 0;
// for loop

for (int i = 1; i<= 100; i++){
    sum = sum + i;
}
System.out.println(sum);

// while loop

sum = 0;
int j = 1;

while(j<=100){
    sum = sum + j;
    j++;
}

System.out.println(sum);

// do while loop

sum = 0;
j = 1;

do{
    sum = sum + j;
    j++;
}
while(j<=100);

System.out.println(sum);

In the last case condition j <= 100 is because, even if the condition of do while turns false, it will still execute once but that doesn't matter in this case as the condition turns true, so it continues to loop just like any other loop statement.

If you want control over how many NAs are valid for each row, try this function. For many survey data sets, too many blank question responses can ruin the results. So they are deleted after a certain threshold. This function will allow you to choose how many NAs the row can have before it's deleted:

delete.na <- function(DF, n=0) {
  DF[rowSums(is.na(DF)) <= n,]
}

By default, it will eliminate all NAs:

delete.na(final)
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
6 ENSG00000221312    0    1    2    3    2

Or specify the maximum number of NAs allowed:

delete.na(final, 2)
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
4 ENSG00000207604    0   NA   NA    1    2
6 ENSG00000221312    0    1    2    3    2

Use this instead:

<input id='tea-submit' type='submit' name = 'submit'    value = 'Tea'>
<input id='coffee-submit' type='submit' name = 'submit' value = 'Coffee'>

int arr[10] = {0, 5, 3, 64};
arr[4] = 5;

EDIT: So I was asked to explain what's happening when you do:

int arr[10] = {0, 5, 3, 64};

you create an array with 10 elements and you allocate values for the first 4 elements of the array.

Also keep in mind that arr starts at index arr[0] and ends at index arr[9] - 10 elements

arr[0] has value 0;
arr[1] has value 5;
arr[2] has value 3;
arr[3] has value 64;

after that the array contains garbage values / zeroes because you didn't allocated any other values

But you could still allocate 6 more values so when you do

arr[4] = 5;

you allocate the value 5 to the fifth element of the array.

You could do this until you allocate values for the last index of the arr that is arr[9];

Sorry if my explanation is choppy, but I have never been good at explaining things.

If you are OK to run Java command line then you can do it with Apache POI HSSF's Excel Extractor. It has a main method that says to be the command line extractor. This one seems to just dump everything out. They point out to this example that converts to CSV. You would have to compile it before you can run it but it too has a main method so you should not have to do much coding per se to make it work.

Another option that might fly but will require some work on the other end is to make your Excel files come to you as Excel XML Data or XML Spreadsheet of whatever MS calls that format these days. It will open a whole new world of opportunities for you to slice and dice it the way you want.

This is my solution(There is a nested LinearLayout):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/item"
            android:layout_width="match_parent"
            android:layout_height="47dp"
            android:background="@drawable/box_arrow_top_bg"
            android:gravity="center"
            android:text="????"
            android:textColor="#666"
            android:textSize="16sp" />
    </LinearLayout>

</LinearLayout>

This works perfectly as we want:

Unzip files:

find . -name "*.zip" | xargs -P 5 -I FILENAME sh -c 'unzip -o -d "$(dirname "FILENAME")" "FILENAME"'

Above command does not create duplicate directories.

Remove all zip files:

find . -depth -name '*.zip' -exec rm {} \;

If you are creating other batch files from your outputs then put a line like this in your batch file

echo %pathname%\foo.exe >part2.txt

then you can have your defined part1.txt and part3.txt already done and have your batch

copy part1.txt + part2.txt +part3.txt thebatyouwanted.bat

UPDATE 11/4/2013:

The reason why this happens is because you have .js or .css at the end of your bundle name which causes ASP.NET to not run the request through MVC and the BundleModule.

The recommended way to fix this for better performance is to remove the .js or .css from your bundle name.

So /bundle/myscripts.js becomes /bundle/myscripts

Alternatively you can modify your web.config in the system.webServer section to run these requests through the BundleModule (which was my original answer)

<modules runAllManagedModulesForAllRequests="true">
  <remove name="BundleModule" />
  <add name="BundleModule" type="System.Web.Optimization.BundleModule" />
</modules>

Edit: I also noticed that if the name ends with 'css' (without the dot), that is a problem as well. I had to change my bundle name from 'DataTablesCSS' to 'DataTablesStyles' to fix my issue.

I may be out fishing here, but doesn't Tomcat by default open to port 8080? Try http://localhost:8080 instead.

npm start -- --port "port number"
