Also you can use postgres fdw system

https://www.postgresql.org/docs/9.5/postgres-fdw.html

You will be able to connect different db in postgres. After that, in one query, you can access tables that are in different databases.

Persistent user input using recursive function:

String

def askName():
    return input("Write your name: ").strip() or askName()

name = askName()

Integer

def askAge():
    try: return int(input("Enter your age: "))
    except ValueError: return askAge()

age = askAge()

and finally, the question requirement:

def askAge():
    try: return int(input("Enter your age: "))
    except ValueError: return askAge()

age = askAge()

responseAge = [
    "You are able to vote in the United States!",
    "You are not able to vote in the United States.",
][int(age < 18)]

print(responseAge)

I also faced the same issue, when I was developing a application which exports project contents into excel file.

I could not found the resolution in forums for my problem, then I check the maximum capacity of excel and found below link which says

"Worksheet size 1,048,576 rows by 16,384 columns" and this was the issue in my case, I was exporting more than that rows. Refer below link for details

If you do the following, you will be able to use opencv build from OpenCV_INSTALL_PATH.

cmake_minimum_required(VERSION 2.8)

SET(OpenCV_INSTALL_PATH /home/user/opencv/opencv-2.4.13/release/)

SET(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")

SET(OpenCV_LIB_DIR "${OpenCV_INSTALL_PATH}/lib")

LINK_DIRECTORIES(${OpenCV_LIB_DIR})

set(OpenCV_LIBS opencv_core opencv_imgproc opencv_calib3d opencv_video opencv_features2d opencv_ml opencv_highgui opencv_objdetect opencv_contrib opencv_legacy opencv_gpu)

# find_package( OpenCV )

project(edge.cpp)

add_executable(edge edge.cpp)

Rather than locks, I suggest you look at long-running transactions, using v$transaction. From there you can join to v$session, which should give you an idea about the UI (try the program and machine columns) as well as the user.

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

If you use Java 8, the following should work:

long count = "0 1 2 3 4.".chars().filter(Character::isWhitespace).count();

This will also work in Java 8 using Eclipse Collections:

int count = Strings.asChars("0 1 2 3 4.").count(Character::isWhitespace);

Note: I am a committer for Eclipse Collections.

I think the best option is:

1. Create a model class as config schema

2. Register in DI: services.Configure(Configuration.GetSection("democonfig"));

3. Get the values as model object from DI in your controller:

   private readonly your_model myConfig;
   public DemoController(IOptions<your_model> configOps)
   {
       this.myConfig = configOps.Value;
   }
   

Call like this

my_function ("", options);

Just Go to Model file of the corresponding Controller and check the primary key filed name

such as

protected $primaryKey = 'info_id';

here info id is field name available in database table

More info can be found at "Primary Keys" section of the docs.

Go into Tools -> Options -> Designers-> Uncheck "Prevent saving changes that require table re-creation". Voila.

That happens because sometimes it is necessary to drop and recreate a table in order to change something. This can take a while, since all data must be copied to a temp table and then re-inserted in the new table. Since SQL Server by default doesn't trust you, you need to say "OK, I know what I'm doing, now let me do my work."

Below are two solutions to select the range A1.

Cells(1,1).Select '(row 1, column 1) 
Range("A1").Select

Also check out this link;

• http://www.excel-vba.com/vba-code-2-6-cells-ranges.htm

We strongly recommend that you use Range instead of Cells to work with cells and groups of cells. It makes your sentences much clearer and you are not forced to remember that column AE is column 31.

The only time that you will use Cells is when you want to select all the cells of a worksheet. For example: Cells.Select To select all cells and then empty all cells of values or formulas you will use: Cells.ClearContents

--

"Cells" is particularly useful when setting ranges dynamically and looping through ranges by using counters. Defining ranges using letters as column numbers may be more transparent on the short run, but it will also make your application more rigid since they are "hard coded" representations - not dynamic.

[Update]
I've just realized why you weren't receiving results back... you have a missing line in your Deserialize method. You were forgetting to assign the results to your obj :

public static T Deserialize<T>(string json)
{
    using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
    {
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
        return (T)serializer.ReadObject(ms);
    } 
}

Also, just for reference, here is the Serialize method :

public static string Serialize<T>(T obj)
{
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    using (MemoryStream ms = new MemoryStream())
    {
        serializer.WriteObject(ms, obj);
        return Encoding.Default.GetString(ms.ToArray());
    }
}

Edit

If you want to use Json.NET here are the equivalent Serialize/Deserialize methods to the code above..

Deserialize:

JsonConvert.DeserializeObject<T>(string json);

Serialize:

JsonConvert.SerializeObject(object o);

This are already part of Json.NET so you can just call them on the JsonConvert class.

Link: Serializing and Deserializing JSON with Json.NET

Now, the reason you're getting a StackOverflow is because of your Properties.

Take for example this one :

[DataMember]
public string unescapedUrl
{
    get { return unescapedUrl; } // <= this line is causing a Stack Overflow
    set { this.unescapedUrl = value; }
}

Notice that in the getter, you are returning the actual property (ie the property's getter is calling itself over and over again), and thus you are creating an infinite recursion.

Properties (in 2.0) should be defined like such :

string _unescapedUrl; // <= private field

[DataMember]
public string unescapedUrl
{
    get { return _unescapedUrl; } 
    set { _unescapedUrl = value; }
}

You have a private field and then you return the value of that field in the getter, and set the value of that field in the setter.

Btw, if you're using the 3.5 Framework, you can just do this and avoid the backing fields, and let the compiler take care of that :

public string unescapedUrl { get; set;}

ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

demo.html

<!DOCTYPE html>
<html ng-app="app">

  <head>
    <script data-require="[email protected]" data-semver="1.0.7" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Compile dynamic HTML</h1>
    <div ng-controller="MyController">
      <textarea ng-model="html"></textarea>
      <div dynamic="html"></div>
    </div>
  </body>

</html>

script.js

var app = angular.module('app', []);

app.directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});

function MyController($scope) {
  $scope.click = function(arg) {
    alert('Clicked ' + arg);
  }
  $scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}

4 GB minus what is in use by the system if you link with /LARGEADDRESSAWARE.

Of course, you should be even more careful with pointer arithmetic if you set that flag.

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

The "no version information available" means that the library version number is lower on the shared object. For example, if your major.minor.patch number is 7.15.5 on the machine where you build the binary, and the major.minor.patch number is 7.12.1 on the installation machine, ld will print the warning.

You can fix this by compiling with a library (headers and shared objects) that matches the shared object version shipped with your target OS. E.g., if you are going to install to RedHat 3.4.6-9 you don't want to compile on Debian 4.1.1-21. This is one of the reasons that most distributions ship for specific linux distro numbers.

Otherwise, you can statically link. However, you don't want to do this with something like PAM, so you want to actually install a development environment that matches your client's production environment (or at least install and link against the correct library versions.)

Advice you get to rename the .so files (padding them with version numbers,) stems from a time when shared object libraries did not use versioned symbols. So don't expect that playing with the .so.n.n.n naming scheme is going to help (much - it might help if you system has been trashed.)

You last option will be compiling with a library with a different minor version number, using a custom linking script: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gnu-linker/scripts.html

To do this, you'll need to write a custom script, and you'll need a custom installer that runs ld against your client's shared objects, using the custom script. This requires that your client have gcc or ld on their production system.

Try this:

$array = array_values($array);

Using array_values()

window.location.hash = '#tries';

This will scroll to the element in question, essentially "focus"ing it.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.writeqrcode_main, container, false);
    // Inflate the layout for this fragment

    txt_name = (TextView) view.findViewById(R.id.name);
    txt_usranme = (TextView) view.findViewById(R.id.surname);
    txt_number = (TextView) view.findViewById(R.id.number);
    txt_province = (TextView) view.findViewById(R.id.province);
    txt_write = (EditText) view.findViewById(R.id.editText_write);
    txt_show1 = (Button) view.findViewById(R.id.buttonShow1);

    txt_show1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e("Onclick","Onclick");

            txt_show1.setVisibility(View.INVISIBLE);
            txt_name.setVisibility(View.VISIBLE);
            txt_usranme.setVisibility(View.VISIBLE);
            txt_number.setVisibility(View.VISIBLE);
            txt_province.setVisibility(View.VISIBLE);
        }
    });
    return view;
}

You OK !!!!

If you want to just uncommit the last commit use this:

git reset HEAD~

work like charm for me.

This code will help you, and it's fairly self-explanatory:

#include <stdio.h>      /* Standard Library of Input and Output */
#include <complex.h>    /* Standard Library of Complex Numbers */

int main() {

    double complex z1 = 1.0 + 3.0 * I;
    double complex z2 = 1.0 - 4.0 * I;

    printf("Working with complex numbers:\n\v");

    printf("Starting values: Z1 = %.2f + %.2fi\tZ2 = %.2f %+.2fi\n", creal(z1), cimag(z1), creal(z2), cimag(z2));

    double complex sum = z1 + z2;
    printf("The sum: Z1 + Z2 = %.2f %+.2fi\n", creal(sum), cimag(sum));

    double complex difference = z1 - z2;
    printf("The difference: Z1 - Z2 = %.2f %+.2fi\n", creal(difference), cimag(difference));

    double complex product = z1 * z2;
    printf("The product: Z1 x Z2 = %.2f %+.2fi\n", creal(product), cimag(product));

    double complex quotient = z1 / z2;
    printf("The quotient: Z1 / Z2 = %.2f %+.2fi\n", creal(quotient), cimag(quotient));

    double complex conjugate = conj(z1);
    printf("The conjugate of Z1 = %.2f %+.2fi\n", creal(conjugate), cimag(conjugate));

    return 0;
}

  with:

creal(z1): get the real part (for float crealf(z1), for long double creall(z1))

cimag(z1): get the imaginary part (for float cimagf(z1), for long double cimagl(z1))

Another important point to remember when working with complex numbers is that functions like cos(), exp() and sqrt() must be replaced with their complex forms, e.g. ccos(), cexp(), csqrt().

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

I am not completely sure what you're trying to achieve by seeking to a specific offset and attempting to load individual values manually, the typical usage of the pickle module is:

# save data to a file
with open('myfile.pickle','wb') as fout:
    pickle.dump([1,2,3],fout)

# read data from a file
with open('myfile.pickle') as fin:
    print pickle.load(fin)

# output
>> [1, 2, 3]

If you dumped a list, you'll load a list, there's no need to load each item individually.

you're saying that you got an error before you were seeking to the -5000 offset, maybe the file you're trying to read is corrupted.

If you have access to the original data, I suggest you try saving it to a new file and reading it as in the example.

This might work:

    div{
    display:inline-block;
    width:100%;
    float:left;
    }

This might be more clear:

from datetime import date, timedelta

start_date = date(2019, 1, 1)
end_date = date(2020, 1, 1)
delta = timedelta(days=1)
while start_date <= end_date:
    print (start_date.strftime("%Y-%m-%d"))
    start_date += delta

Updated @sqiller's function for my purposes

    -- cleanse phone number string
    WHILE PATINDEX('%[^0-9]%',@PhoneNumber) > 0
        SET @PhoneNumber = REPLACE(@PhoneNumber,
                SUBSTRING(@PhoneNumber,PATINDEX('%[^0-9]%',@PhoneNumber),1),'')

    IF SUBSTRING(@PhoneNumber,1,1) = '1' AND LEN(@PhoneNumber) = 11
        SET @PhoneNumber = SUBSTRING(@PhoneNumber, 2, 10)

    -- any phone numbers without 10 characters are set to default
    IF LEN(@PhoneNumber) <> 10
        RETURN @DefaultIfUnknown

    -- build US standard phone number
    SET @PhoneNumber = '(' + SUBSTRING(@PhoneNumber,1,3) + ') ' +
                SUBSTRING(@PhoneNumber,4,3) + '-' + SUBSTRING(@PhoneNumber,7,4)

    RETURN @PhoneNumber
END

By keys() and values() methods of dictionary and zip.

zip will return a list of tuples which acts like an ordered dictionary.

Demo:

>>> d = { 'a': 1, 'b': 2, 'c': 3 }
>>> zip(d.keys(), d.values())
[('a', 1), ('c', 3), ('b', 2)]
>>> zip(d.values(), d.keys())
[(1, 'a'), (3, 'c'), (2, 'b')]

In addition to the other two answers, I think the indentations are also incorrect in the last two conditions. The conditions are that one name is longer than the other and they need to start with 'elif' and with no indentations. If you put it within the first condition (by giving it four indentations from the margin), it ends up being contradictory because the lengths of the names cannot be equal and different at the same time.

    else:
        print ("The names are different, but are the same length")
elif len(name1) > len(name2):
    print ("{0} is longer than {1}".format(name1, name2))

Try the SetField method:

By passing column object :

table.Rows[rowIndex].SetField(column, value);

By Passing column index :

table.Rows[rowIndex].SetField(0 /*column index*/, value);

By Passing column name as string :

table.Rows[rowIndex].SetField("product_name" /*columnName*/, value);

For people who needs to validate years earlier than year 1900, following should do the trick. Actually this is same as the above answer given by [@OammieR][1] BUT with years including 1800 - 1899.

/^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((18|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((18|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/

Hope this helps someone who needs to validate years earlier than 1900, such as 01/01/1855, etc.

Thanks @OammieR for the initial idea.

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

I write this answer because I was looking for a way to plot together the histograms of different groups. What follows is not very smart, but it works fine for me. I use Numpy to compute the histogram and Bokeh for plotting. I think it is self-explanatory, but feel free to ask for clarifications and I'll be happy to add details (and write it better).

figures = {
    'Transit': figure(title='Transit', x_axis_label='speed [km/h]', y_axis_label='frequency'),
    'Driving': figure(title='Driving', x_axis_label='speed [km/h]', y_axis_label='frequency')
}

cols = {'Vienna': 'red', 'Turin': 'blue', 'Rome': 'Orange'}
for gr in df_trips.groupby(['locality', 'means']):
    locality = gr[0][0]
    means = gr[0][1]
    fig = figures[means]
    h, b = np.histogram(pd.DataFrame(gr[1]).speed.values)
    fig.vbar(x=b[1:], top=h, width=(b[1]-b[0]), legend_label=locality, fill_color=cols[locality], alpha=0.5)

show(gridplot([
    [figures['Transit']],
    [figures['Driving']],
]))

Maybe remove the semi-colon after set because now the where statement doesn't belong to the update statement. Also the idRequest could be a problem, better write BookingRequest.idRequest

Sorry, you forgot the namespace. You need:

XmlNamespaceManager ns = new XmlNamespaceManager(myXmlDoc.NameTable);
ns.AddNamespace("hl7","urn:hl7-org:v3");
XmlNode idNode = myXmlDoc.SelectSingleNode("/My_RootNode/hl7:id", ns);

In fact, whether here or in web services, getting null back from an XPath operation or anything that depends on XPath usually indicates a problem with XML namespaces.

I had a very similar requirement (importing a base64 encoded image from an external xml import file. After using xml2json-light library to convert to a json object, I was able to leverage insight from cuixiping's answer above to convert the incoming b64 encoded image to a file object.

const imgName = incomingImage['FileName'];
const imgExt = imgName.split('.').pop();
let mimeType = 'image/png';
if (imgExt.toLowerCase() !== 'png') {
    mimeType = 'image/jpeg';
}
const imgB64 = incomingImage['_@ttribute'];
const bstr = atob(imgB64);
let n = bstr.length;
const u8arr = new Uint8Array(n);
while (n--) {
  u8arr[n] = bstr.charCodeAt(n);
}
const file = new File([u8arr], imgName, {type: mimeType});

My incoming json object had two properties after conversion by xml2json-light: FileName and _@ttribute (which was b64 image data contained in the body of the incoming element.) I needed to generate the mime-type based on the incoming FileName extension. Once I had all the pieces extracted/referenced from the json object, it was a simple task (using cuixiping's supplied code reference) to generate the new File object which was completely compatible with my existing classes that expected a file object generated from the browser element.

Hope this helps connects the dots for others.

I adapted the SetTags() search function above (which should be replaced by the equivalent set tags+=./tags;/) to work for cscope. Seems to work!

"cscope file-searching alternative
function SetCscope()
    let curdir = getcwd()

    while !filereadable("cscope.out") && getcwd() != "/"
            cd ..
                endwhile

    if filereadable("cscope.out")
            execute "cs add " . getcwd() . "/cscope.out"
                endif

    execute "cd " . curdir
    endfunction

call SetCscope()

I just use this solution in Kotlin:

 var date : String = DateFormat.format("EEEE dd-MMM-yyyy HH:mm a" , Date()) as String

every 3 posts?

if($counter % 3 == 0){
    echo IMAGE;
}

With a List you can try

List<String> strings = new ArrayList<>(Arrays.asList("First", "Second", "Third", "Fourth", "Fifth")); // An example list of Strings
strings.stream() // Turn the list into a Stream
    .collect(HashMap::new, (h, o) -> h.put(h.size(), o), (h, o) -> {}) // Create a map of the index to the object
        .forEach((i, o) -> { // Now we can use a BiConsumer forEach!
            System.out.println(String.format("%d => %s", i, o));
        });

Output:

0 => First
1 => Second
2 => Third
3 => Fourth
4 => Fifth

I resolved a similar problem by border-color: inherit

, see:

<li style="border-color: <?php echo $hex ?>;">...</li>

li {
    border-width: 0;
}

li:before {
    content: '';
    display: inline-block;
    float: none;
    margin-right: 10px;
    border-width: 4px;
    border-style: solid;
    border-color: inherit;
}

To avoid try catch, use:

String s = "some text here";
byte[] b = s.getBytes(StandardCharsets.UTF_8);
System.out.println(b.length);

I have solved the same problem using the link with some modifications in it. Search filter on RecyclerView with Cards. Is it even possible? (hope this helps).

Here is my adapter class

public class ContactListRecyclerAdapter extends RecyclerView.Adapter<ContactListRecyclerAdapter.ContactViewHolder> implements Filterable {

Context mContext;
ArrayList<Contact> customerList;
ArrayList<Contact> parentCustomerList;


public ContactListRecyclerAdapter(Context context,ArrayList<Contact> customerList)
{
    this.mContext=context;
    this.customerList=customerList;
    if(customerList!=null)
    parentCustomerList=new ArrayList<>(customerList);
}

   // other overrided methods

@Override
public Filter getFilter() {
    return new FilterCustomerSearch(this,parentCustomerList);
}
}

//Filter class

import android.widget.Filter;
import java.util.ArrayList;


public class FilterCustomerSearch extends Filter
{
private final ContactListRecyclerAdapter mAdapter;
ArrayList<Contact> contactList;
ArrayList<Contact> filteredList;

public FilterCustomerSearch(ContactListRecyclerAdapter mAdapter,ArrayList<Contact> contactList) {
    this.mAdapter = mAdapter;
    this.contactList=contactList;
    filteredList=new ArrayList<>();
}

@Override
protected FilterResults performFiltering(CharSequence constraint) {
    filteredList.clear();
    final FilterResults results = new FilterResults();

    if (constraint.length() == 0) {
        filteredList.addAll(contactList);
    } else {
        final String filterPattern = constraint.toString().toLowerCase().trim();

        for (final Contact contact : contactList) {
            if (contact.customerName.contains(constraint)) {
                filteredList.add(contact);
            }
            else if (contact.emailId.contains(constraint))
            {
                filteredList.add(contact);

            }
            else if(contact.phoneNumber.contains(constraint))
                filteredList.add(contact);
        }
    }
    results.values = filteredList;
    results.count = filteredList.size();
    return results;
}

@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
    mAdapter.customerList.clear();
    mAdapter.customerList.addAll((ArrayList<Contact>) results.values);
    mAdapter.notifyDataSetChanged();
}

}

//Activity class

    // Inflate the menu; this adds items to the action bar if it is present.

    MenuInflater inflater = getMenuInflater();
    // Inflate menu to add items to action bar if it is present.
    inflater.inflate(R.menu.menu_customer_view_and_search, menu);
    // Associate searchable configuration with the SearchView
    SearchManager searchManager =
            (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView =
            (SearchView) menu.findItem(R.id.menu_search).getActionView();
    searchView.setQueryHint("Search Customer");
    searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override

            return false;

        @Override
        public boolean onQueryTextChange(String newText) {
            if(fragment instanceof CustomerDetailsViewWithModifyAndSearch)
                ((CustomerDetailsViewWithModifyAndSearch)fragment).adapter.getFilter().filter(newText);
            return false;
        }
    });



    return true;
}
}

In OnQueryTextChangeListener() method use your adapter. I have casted it to fragment as my adpter is in fragment. You can use the adapter directly if its in your activity class.

With custom index:

$arr=array("a"=>"one", "b"=>"two");
    $arr=array("c"=>"three", "d"=>"four").$arr;

    print_r($arr);
    -------------------
    output:
    ----------------
    Array
    (
    [c]=["three"]
    [d]=["four"]
    [a]=["two"]
    [b]=["one"]
    )

var sibling = node.nextSibling;

This will return the sibling immediately after it, or null no more siblings are available. Likewise, you can use previousSibling.

[Edit] On second thought, this will not give the next div tag, but the whitespace after the node. Better seems to be

var sibling = node.nextElementSibling;

There also exists a previousElementSibling.

From Dockerfile reference:

• The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag.

• The ENV instruction sets the environment variable <key> to the value <value>.
  The environment variables set using ENV will persist when a container is run from the resulting image.

So if you need build-time customization, ARG is your best choice.
If you need run-time customization (to run the same image with different settings), ENV is well-suited.

If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable

Given the number of combinations involved, using ENV to set those features at runtime is best here.

But you can combine both by:

• building an image with a specific ARG
• using that ARG as an ENV

That is, with a Dockerfile including:

ARG var
ENV var=${var}

You can then either build an image with a specific var value at build-time (docker build --build-arg var=xxx), or run a container with a specific runtime value (docker run -e var=yyy)

You had the identity node as a child of authentication node. That was the issue. As in the example above, authentication and identity nodes must be children of the system.web node

The general methodology would be to iterate through the ArrayList, and insert the values into the HashMap. An example is as follows:

HashMap<String, Product> productMap = new HashMap<String, Product>();
for (Product product : productList) {
   productMap.put(product.getProductCode(), product);
}

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Easiest way to do it would be this

std::string myWord = "myWord";
char myArray[myWord.size()+1];//as 1 char space for null is also required
strcpy(myArray, myWord.c_str());

A bit verbose, but it's the standard way of parsing and formatting dates in Java:

DateFormat formatter = new SimpleDateFormat("HH:mm:ss");
try {
  Date dt = formatter.parse("08:19:12");
  Calendar cal = Calendar.getInstance();
  cal.setTime(dt);
  int hour = cal.get(Calendar.HOUR);
  int minute = cal.get(Calendar.MINUTE);
  int second = cal.get(Calendar.SECOND);
} catch (ParseException e) {
  // This can happen if you are trying to parse an invalid date, e.g., 25:19:12.
  // Here, you should log the error and decide what to do next
  e.printStackTrace();
}

An overkill approach: in inline css in the div did the trick:

style="margin:0 auto;
margin-left:auto;
margin-right:auto;
align:center;
text-align:center;"

Centers like a charm!

You'll need to use fs for that: http://nodejs.org/api/fs.html

And in particular the fs.rename() function:

var fs = require('fs');
fs.rename('/path/to/Afghanistan.png', '/path/to/AF.png', function(err) {
    if ( err ) console.log('ERROR: ' + err);
});

Put that in a loop over your freshly-read JSON object's keys and values, and you've got a batch renaming script.

fs.readFile('/path/to/countries.json', function(error, data) {
    if (error) {
        console.log(error);
        return;
    }

    var obj = JSON.parse(data);
    for(var p in obj) {
        fs.rename('/path/to/' + obj[p] + '.png', '/path/to/' + p + '.png', function(err) {
            if ( err ) console.log('ERROR: ' + err);
        });
    }
});

(This assumes here that your .json file is trustworthy and that it's safe to use its keys and values directly in filenames. If that's not the case, be sure to escape those properly!)

Sessions Step By Step

1. Defining session before everything, No output should be before that, NO OUTPUT

   <?php
   session_start();
   ?>
   

2. Set your session inside a page and then you have access in that page. For example this is page 1.php

   <?php
      //This is page 1 and then we will use session that defined from this page:
       session_start();
       $_SESSION['email']='[email protected]';
   ?>
   

3. Using and Getting session in 2.php

    <?php
   
   //In this page I am going to use session:
   
     session_start();
     if($_SESSION['email']){
     echo 'Your Email Is Here!  :) ';
     }
    ?>
   

NOTE: Comments don't have output.

The simple way to use XMLHttpRequest with pure JavaScript. You can set custom header but it's optional used based on requirement.

1. Using POST Method:

window.onload = function(){
    var request = new XMLHttpRequest();
    var params = "UID=CORS&name=CORS";

    request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            console.log(this.responseText);
        }
    };

    request.open('POST', 'https://www.example.com/api/createUser', true);
    request.setRequestHeader('api-key', 'your-api-key');
    request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    request.send(params);
}

You can send params using POST method.

2. Using GET Method:

Please run below example and will get an JSON response.

window.onload = function(){_x000D_
    var request = new XMLHttpRequest();_x000D_
_x000D_
    request.onreadystatechange = function() {_x000D_
        if (this.readyState == 4 && this.status == 200) {_x000D_
            console.log(this.responseText);_x000D_
        }_x000D_
    };_x000D_
_x000D_
    request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
    request.send();_x000D_
}

This is a bit old but I ran into the requirement so here is the solution I came up with.

The Problem:

Our development team maintains many .NET web application products we are migrating to AngularJS/Bootstrap. VS2010 does not lend itself easily to custom build processes and my developers are routinely working on multiple releases of our products. Our VCS is Subversion (I know, I know. I'm trying to move to Git but my pesky marketing staff is so demanding) and a single VS solution will include several separate projects. I needed my staff to have a common method for initializing their development environment without having to install the same Node packages (gulp, bower, etc.) several times on the same machine.

TL;DR:

1. Need "npm install" to install the global Node/Bower development environment as well as all locally required packages for a .NET product.

2. Global packages should be installed only if not already installed.

3. Local links to global packages must be created automatically.

The Solution:

We already have a common development framework shared by all developers and all products so I created a NodeJS script to install the global packages when needed and create the local links. The script resides in "....\SharedFiles" relative to the product base folder:

/*******************************************************************************

Now if I want to update a global tool for our developers, I update the "packages" object and check in the new script. My developers check it out and either run it with "node npm-setup.js" or by "npm install" from any of the products under development to update the global environment. The whole thing takes 5 minutes.

In addition, to configure the environment for the a new developer, they must first only install NodeJS and GIT for Windows, reboot their computer, check out the "Shared Files" folder and any products under development, and start working.

The "package.json" for the .NET product calls this script prior to install:

{ 
"name"                    : "Books",
"description"             : "Node (npm) configuration for Books Database Web Application Tools",
"version"                 : "2.1.1",
"private"                 : true,
"scripts":
  {
  "preinstall"            : "node ../../SharedFiles/npm-setup.js links",
  "postinstall"           : "bower install"
  },
"dependencies": {}
}

Notes

• Note the script reference requires forward slashes even in a Windows environment.

• "npm ls" will give "npm ERR! extraneous:" messages for all packages locally linked because they are not listed in the "package.json" "dependencies".

Edit 1/29/16

The updated npm-setup.js script above has been modified as follows:

• Package "version" in var packages is now the "package" value passed to npm install on the command line. This was changed to allow for installing packages from somewhere other than the registered repository.

• If the package is already installed but is not the one requested, the existing package is removed and the correct one installed.

• For reasons unknown, npm will periodically throw an EBUSY error (-4082) when performing an install or link. This error is trapped and the command re-executed. The error rarely happens a second time and seems to always clear up.

Wait for Java 8:

List<Person> olderThan30 = 
  //Create a Stream from the personList
  personList.stream().
  //filter the element to select only those with age >= 30
  filter(p -> p.age >= 30).
  //put those filtered elements into a new List.
  collect(Collectors.toList());

As of Django 1.9, the way to do this is by using __date on a datetime object.

For example: MyObject.objects.filter(datetime_attr__date=datetime.date(2009,8,22))

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

After I had tried everything described, I looked up into the folder permission of brew in /usr/local/etc/. Somehow the permission were changed and I was not able to open the folder. I changed the folder permissions(with chmod) with same permissions as the other folders and brew start working.

For anyone looking for a Kotlin implementation see below.

Note that the OnBackPressedCallback only seems to work for providing custom back behavior to the built-in software/hardware back button and not the back arrow button/home as up button within the actionbar/toolbar. To also override the behavior for the actionbar/toolbar back button I'm providing the solution that's working for me. If this is a bug or you are aware of a better solution for that case please comment.

You just need to use the shape: CircleBorder()

  color: Colors.blue,
  textColor: Colors.white,

    Icons.camera_alt,
    size: 24,

After struggling with all available options, I ended up writing a JWT token based SessionStore provider (the session travels inside a cookie, and no backend storage is needed).

http://www.drupalonwindows.com/en/content/token-sessionstate

Advantages:

• Drop-in replacement, no changes to your code are needed
• Scale better than any other centralized store, as no session storage backend is needed.
• Faster than any other session storage, as no data needs to be retrieved from any session storage
• Consumes no server resources for session storage.
• Default non-blocking implementation: concurrent request won't block each other and hold a lock on the session
• Horizontally scale your application: because the session data travels with the request itself you can have multiple web heads without worrying about session sharing.

I think you just need to create your volume outside docker first with a docker create -v /location --name and then reuse it.

And by the time I used to use docker a lot, it wasn't possible to use a static docker volume with dockerfile definition so my suggestion is to try the command line (eventually with a script ) .

Assuming you're looking for a quick tactical fix, what you need to do is make sure the cell image is initialized and also that the cell's row is still visible, e.g:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    MyCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    cell.poster.image = nil; // or cell.poster.image = [UIImage imageNamed:@"placeholder.png"];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://myurl.com/%@.jpg", self.myJson[indexPath.row][@"movieId"]]];

    NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if (data) {
            UIImage *image = [UIImage imageWithData:data];
            if (image) {
                dispatch_async(dispatch_get_main_queue(), ^{
                    MyCell *updateCell = (id)[tableView cellForRowAtIndexPath:indexPath];
                    if (updateCell)
                        updateCell.poster.image = image;
                });
            }
        }
    }];
    [task resume];

    return cell;
}

The above code addresses a few problems stemming from the fact that the cell is reused:

1. You're not initializing the cell image before initiating the background request (meaning that the last image for the dequeued cell will still be visible while the new image is downloading). Make sure to nil the image property of any image views or else you'll see the flickering of images.

2. A more subtle issue is that on a really slow network, your asynchronous request might not finish before the cell scrolls off the screen. You can use the UITableView method cellForRowAtIndexPath: (not to be confused with the similarly named UITableViewDataSource method tableView:cellForRowAtIndexPath:) to see if the cell for that row is still visible. This method will return nil if the cell is not visible.

   The issue is that the cell has scrolled off by the time your async method has completed, and, worse, the cell has been reused for another row of the table. By checking to see if the row is still visible, you'll ensure that you don't accidentally update the image with the image for a row that has since scrolled off the screen.

3. Somewhat unrelated to the question at hand, I still felt compelled to update this to leverage modern conventions and API, notably:

   • Use NSURLSession rather than dispatching -[NSData contentsOfURL:] to a background queue;

   • Use dequeueReusableCellWithIdentifier:forIndexPath: rather than dequeueReusableCellWithIdentifier: (but make sure to use cell prototype or register class or NIB for that identifier); and

   • I used a class name that conforms to Cocoa naming conventions (i.e. start with the uppercase letter).

Even with these corrections, there are issues:

1. The above code is not caching the downloaded images. That means that if you scroll an image off screen and back on screen, the app may try to retrieve the image again. Perhaps you'll be lucky enough that your server response headers will permit the fairly transparent caching offered by NSURLSession and NSURLCache, but if not, you'll be making unnecessary server requests and offering a much slower UX.

2. We're not canceling requests for cells that scroll off screen. Thus, if you rapidly scroll to the 100th row, the image for that row could be backlogged behind requests for the previous 99 rows that aren't even visible anymore. You always want to make sure you prioritize requests for visible cells for the best UX.

The simplest fix that addresses these issues is to use a UIImageView category, such as is provided with SDWebImage or AFNetworking. If you want, you can write your own code to deal with the above issues, but it's a lot of work, and the above UIImageView categories have already done this for you.

A better solution is to use the array_filter function:

$display_related_tags =
    array_filter($display_related_tags, function($e) use($found_tag){
        return $e != $found_tag['name'];
    });

As the php documentation reads:

As foreach relies on the internal array pointer in PHP 5, changing it within the loop may lead to unexpected behavior.

In PHP 7, foreach does not use the internal array pointer.

For me, it happened when I used Proguard, so by trying all the solutions I cleaned my project and pressed the debug button on Android Studio and it started debugging

those various ways of switch ...

# by index
switch(1, "one", "two")
## [1] "one"


# by index with complex expressions
switch(2, {"one"}, {"two"})
## [1] "two"


# by index with complex named expression
switch(1, foo={"one"}, bar={"two"})
## [1] "one"


# by name with complex named expression
switch("bar", foo={"one"}, bar={"two"})
## [1] "two"

You can use the following command to clear out ALL variables. Be careful because it you cannot get your variables back.

rm(list=ls(all=TRUE))

You can fix this easily with jQuery - and a little ugly hack :-)

I have a asp.net page with a ReportViewer user control.

 <rsweb:ReportViewer ID="ReportViewer1" runat="server"...

In the document ready event I then start a timer and look for the element which needs the overflow fix (as previous posts):

 <script type="text/javascript">
    $(function () {
        // Bug-fix on Chrome and Safari etc (webkit)
        if ($.browser.webkit) {
            // Start timer to make sure overflow is set to visible
             setInterval(function () {
                var div = $('#<%=ReportViewer1.ClientID %>_fixedTable > tbody > tr:last > td:last > div')
                div.css('overflow', 'visible');
            }, 1000);
        }
    });
</script>

Better than assuming it has a certain id. You can adjust the timer to whatever you like. I set it to 1000 ms here.

You're most likely not reading the entire error message. If you look above the "Command CompileSwift failed with a nonzero exit code" message you should find some specification like this:

In this example I had two files with the same name. Once I fixed it everything worked as it should.

Here's another way to do it :) The concept is to create a clip-path polygon with the wave as one side.

This approach is fairly flexible. You can change the position (left, right, top or bottom) in which the wave appears, change the wave function to any function(t) which maps to [0,1]). The polygon can also be used for shape-outside, which lets text flow around the wave when in 'left' or 'right' orientation.

At the end, an example you can uncomment which demonstrates animating the wave.

It is easier to remove the "Default Web Site" and create a new one if you do not have any limitations.

I did it and my problem solved.

Try casting your column to a numeric like:

SELECT ROUND(cast(some_column as numeric),2) FROM table

package will add packaged jar or war to your target folder, We can check it when, we empty the target folder (using mvn clean) and then run mvn package.
install will do all the things that package does, additionally it will add packaged jar or war in local repository as well. We can confirm it by checking in your .m2 folder.

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

For those it might help, I use this list as a reference to define my content-type when I have to deal with images on my app.

It says that jpg extension can be declared with Content-type : image/jpeg

There isn't any image/jpg attribute for content-type.

Given that none of the answers here worked for me, I finally tracked down my issue connecting to Bitbucket (or Github, doesn't matter in this case) with ssh -vT [email protected].

In my case, the failure was due to using a DSA key instead of RSA, and apparently my SSH client no longer allows that.

debug1: Skipping ssh-dss key /c/Users/USER/.ssh/id_dsa for not in PubkeyAcceptedKeyTypes

The solution was to add this to .ssh/config:

Host *
    PubkeyAcceptedKeyTypes +ssh-dss

This elegantly appends the ssh-dss key type to all existing accepted public key types and after this was done, git can now ssh into Bitbucket no problem.

The easiest way to quickly view large varchar/text column:

declare @t varchar(max)

select @t = long_column from table

print @t

Modifying @brcolow's answer a bit

I use GateOne from the synocommunity.

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

Here is the best solution to use Gif Image. Add SDWebImage from Github in your project.

#import "UIImage+GIF.h"

_imageViewAnimatedGif.image= [UIImage sd_animatedGIFNamed:@"thumbnail"];

(3) Collection myCollection = new ArrayList<?>();

I am using this typically. And only if I need List methods, I will use List. Same with ArrayList. You always can switch to more "narrow" interface, but you can't switch to more "wide".

If you're in netbeans you can right click in the test method and click "Run Focused Test Method".

A good example of a situation when @see can be useful would be implementing or overriding an interface/abstract class method. The declaration would have javadoc section detailing the method and the overridden/implemented method could use a @see tag, referring to the base one.

If your app is in background, Firebase will not trigger onMessageReceived(). Why.....? I have no idea. In this situation, I do not see any point in implementing FirebaseMessagingService.

According to docs, if you want to process background message arrival, you have to send 'click_action' with your message. But it is not possible if you send message from Firebase console, only via Firebase API. It means you will have to build your own "console" in order to enable marketing people to use it. So, this makes Firebase console also quite useless!

There is really good, promising, idea behind this new tool, but executed badly.

I suppose we will have to wait for new versions and improvements/fixes!

If you are using Python 3.6 or newer, you can use f-string:

>>> test = "have it break."
>>> selectiveEscape = f"Print percent % in sentence and not {test}"
>>> print(selectiveEscape)
... Print percent % in sentence and not have it break.

According to BOL:

Indexed views and indexes on computed columns store results in the database for later reference. The stored results are valid only if all connections referring to the indexed view or indexed computed column can generate the same result set as the connection that created the index.

In order to create a table with a persisted, computed column, the following connection settings must be enabled:

SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON
SET NUMERIC_ROUNDABORT ON
SET QUOTED_IDENTIFIER ON

These values are set on the database level and can be viewed using:

SELECT 
    is_ansi_nulls_on,
    is_ansi_padding_on,
    is_ansi_warnings_on,
    is_arithabort_on,
    is_concat_null_yields_null_on,
    is_numeric_roundabort_on,
    is_quoted_identifier_on
FROM sys.databases

However, the SET options can also be set by the client application connecting to SQL Server.

A perfect example is SQL Server Management Studio which has the default values for SET ANSI_NULLS and SET QUOTED_IDENTIFIER both to ON. This is one of the reasons why I could not initially duplicate the error you posted.

Anyway, to duplicate the error, try this (this will override the SSMS default settings):

SET ANSI_NULLS ON
SET ANSI_PADDING OFF
SET ANSI_WARNINGS OFF
SET ARITHABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET NUMERIC_ROUNDABORT OFF
SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE T1 (
    ID INT NOT NULL,
    TypeVal AS ((1)) PERSISTED NOT NULL
) 

You can fix the test case above by using:

SET ANSI_PADDING ON
SET ANSI_WARNINGS ON

I would recommend tweaking these two settings in your script before the creation of the table and related indexes.

Try

$('table#test tr#3').remove();

It looks like you are calling next even if the scanner no longer has a next element to provide... throwing the exception.

while(!file.next().equals(treasure)){
        file.next();
        }

Should be something like

boolean foundTreasure = false;

while(file.hasNext()){
     if(file.next().equals(treasure)){
          foundTreasure = true;
          break; // found treasure, if you need to use it, assign to variable beforehand
     }
}
    // out here, either we never found treasure at all, or the last element we looked as was treasure... act accordingly

If you want to use flexbox for this, you should be able to, by doing this (display: flex on the container, flex: 1 on the items, and text-align: right on .c):

.main { display: flex; }
.a, .b, .c {
    background: #efefef;
    border: 1px solid #999;
    flex: 1;
}
.b { text-align: center; }
.c { text-align: right; }

...or alternatively (even simpler), if the items don't need to meet, you can use justify-content: space-between on the container and remove the text-align rules completely:

.main { display: flex; justify-content: space-between; }
.a, .b, .c { background: #efefef; border: 1px solid #999; }

Here's a demo on Codepen to allow you to quickly try the above.

Not the most beautiful way of doing it I guess:

git log --pretty=oneline | wc -l

This gives you a number then

git log HEAD~<The number minus one>

After spent lot of hours, I just find out the solution, just add this simple line.

backgroundColor = .white

Hope this help you!

I know this question is for Java 8, but with Java 9 you could use:

public static List<LocalDate> getDatesBetween(LocalDate startDate, LocalDate endDate) {
    return startDate.datesUntil(endDate)
      .collect(Collectors.toList());

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

I ran into this error message on 2 separate occasions, with lazy loading in Angular 7 and the above did not help. For both of the below to work you MUST stop and restart ng serve for it to completely update correctly.

1) First time I had somehow incorrectly imported my AppModule into the lazy loaded feature module. I removed this import from the lazy loaded module and it started working again.

2) Second time I had a separate CoreModule that I was importing into the AppModule AND same lazy loaded module as #1. I removed this import from the lazy loaded module and it started working again.

Basically, check your hierarchy of imports and pay close attention to the order of the imports (if they are imported where they should be). Lazy loaded modules only need their own route component / dependencies. App and parent dependencies will be passed down whether they are imported into AppModule, or imported from another feature module that is NOT-lazy loaded and already imported in a parent module.

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

There is a great implementation of NavigationDrawer that follows the Google Material Design Guidelines (and compatible down to API 10) - The MaterialDrawer library (link to GitHub). As of time of writing, May 2017, it's actively supported.

It's available in Maven Central repo. Gradle dependency setup:

compile 'com.mikepenz:materialdrawer:5.9.1'

Maven dependency setup:

<dependency>

This worked for me:

String dat="02/08/2017";
long date=new SimpleDateFormat("dd/MM/yyyy").parse(dat,newParsePosition(0)).getTime();
java.sql.Date dbDate=new java.sql.Date(date);
System.out.println(dbDate);

Also make sure the user issuing the query has been granted the necessary permissions.

For queries on tables you need to grant SELECT permission.
For queries on other object types (e.g. stored procedures) you need to grant EXECUTE permission.

Look for the hidden .android folder in your user home folder. You might rename or delete this folder, recreate your AVD, and restart the emulator. It could be there is a .ini file in that folder that has that setting munged.

You can't. The switch statement can only contain case statements which are compile time constants and which evaluate to an integer (Up to Java 6 and a string in Java 7).

What you are looking for is called "pattern matching" in functional programming.

Just use the following methods to create a 2-D vector.

int rows, columns;        

// . . .

vector < vector < int > > Matrix(rows, vector< int >(columns,0));

OR

vector < vector < int > > Matrix;

Matrix.assign(rows, vector < int >(columns, 0));

//Do your stuff here...

This will create a Matrix of size rows * columns and initializes it with zeros because we are passing a zero(0) as a second argument in the constructor i.e vector < int > (columns, 0).

Turns out for me that SET NOCOUNT ON was set in the stored procedure script (by default on SQL Server Management Studio) and SqlCommand.ExecuteNonQuery(); always returned -1.

I just set it off: SET NOCOUNT OFF without needing to use @@ROWCOUNT.

More details found here : SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Create a xml file under your drawable folder with following code. (The name of the file I created is rounded_corner.xml)

rounded_corner.xml

    <?xml version="1.0" encoding="utf-8"?>
    <shape
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">

        <!-- view background color -->
        <solid
            android:color="#a9c5ac" >
        </solid>

        <!-- view border color and width -->
        <stroke
            android:width="3dp"
            android:color="#1c1b20" >
        </stroke>

        <!-- If you want to add some padding -->
        <padding
            android:left="4dp"
            android:top="4dp"
            android:right="4dp"
            android:bottom="4dp"    >
        </padding>

        <!-- Here is the corner radius -->
        <corners
            android:radius="10dp"   >
        </corners>
    </shape>

And keep this drawable as background for the view to which you want to keep rounded corner border. Let’s keep it for a LinearLayout

    <LinearLayout android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/rounded_corner"
            android:layout_centerInParent="true">

            <TextView android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="Hi, This layout has rounded corner borders ..."
                android:gravity="center"
                android:padding="5dp"/>

    </LinearLayout>

For readability, I'd go with

char * s = malloc(snprintf(NULL, 0, "%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

If your platform supports GNU extensions, you could also use asprintf():

char * s = NULL;
asprintf(&s, "%s %s", first, second);

If you're stuck with the MS C Runtime, you have to use _scprintf() to determine the length of the resulting string:

char * s = malloc(_scprintf("%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

The following will most likely be the fastest solution:

size_t len1 = strlen(first);
size_t len2 = strlen(second);

char * s = malloc(len1 + len2 + 2);
memcpy(s, first, len1);
s[len1] = ' ';
memcpy(s + len1 + 1, second, len2 + 1); // includes terminating null

Looks like divs will not go outside of their body's width. Even within another div.

I threw this up to test (without a doctype though) and it does not work as thought.

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
}_x000D_
.slide {_x000D_
    float: left;_x000D_
}

<div class="slideContainer">_x000D_
    <div class="slide" style="background: #f00">Some content Some content Some content Some content Some content Some content</div>_x000D_
    <div class="slide" style="background: #ff0">More content More content More content More content More content More content</div>_x000D_
    <div class="slide" style="background: #f0f">Even More content! Even More content! Even More content!</div>_x000D_
</div>

What i am thinking is that the inner div's could be loaded through an iFrame, since that is another page and its content could be very wide.

Anaconda is a very large installation ~ 2 GB and is most useful for those users who are not familiar with installing modules or packages with other package managers.

Anaconda seems to be promoting itself as the official package manager of Jupyter. It's not. Anaconda bundles Jupyter, R, python, and many packages with its installation.

Anaconda is not necessary for installing Jupyter Lab or the R kernel. There is plenty of information available elsewhere for installing Jupyter Lab or Notebooks. There is also plenty of information elsewhere for installing R studio. The following shows how to install the R kernel directly from R Studio:

To install the R kernel, without Anaconda, start R Studio. In the R terminal window enter these three commands:

install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()

Done. Next time Jupyter is opened, the R kernel will be available.

In C and C++

unsigned = unsigned int (Integer type)
signed   = signed int (Integer type)

An unsigned integer containing n bits can have a value between 0 and (2^n-1) , which is 2^n different values.

An unsigned integer is either positive or zero.

Signed integers are stored in a computer using 2's complement.

I managed to remove the errors by disabling the validations:

{
    "javascript.validate.enable": false,
    "html.validate.styles": false,
    "html.validate.scripts": false,
    "css.validate": false,
    "scss.validate": false
}

Obs: My project is a PWA using StyledComponents, React, Flow, Eslint and Prettier.

Just a reminder of a mistake I made myself too, the

 __block

declaration must be done when first declaring the variable, that is, OUTSIDE of the block, not inside of it. This should resolve problems mentioned in the comments about the variable not retaining its value outside of the block.

EXIT_FAILURE, either in a return statement in main or as an argument to exit(), is the only portable way to indicate failure in a C or C++ program. exit(1) can actually signal successful termination on VMS, for example.

If you're going to be using EXIT_FAILURE when your program fails, then you might as well use EXIT_SUCCESS when it succeeds, just for the sake of symmetry.

On the other hand, if the program never signals failure, you can use either 0 or EXIT_SUCCESS. Both are guaranteed by the standard to signal successful completion. (It's barely possible that EXIT_SUCCESS could have a value other than 0, but it's equal to 0 on every implementation I've ever heard of.)

Using 0 has the minor advantage that you don't need #include <stdlib.h> in C, or #include <cstdlib> in C++ (if you're using a return statement rather than calling exit()) -- but for a program of any significant size you're going to be including stdlib directly or indirectly anyway.

For that matter, in C starting with the 1999 standard, and in all versions of C++, reaching the end of main() does an implicit return 0; anyway, so you might not need to use either 0 or EXIT_SUCCESS explicitly. (But at least in C, I consider an explicit return 0; to be better style.)

(Somebody asked about OpenVMS. I haven't used it in a long time, but as I recall odd status values generally denote success while even values denote failure. The C implementation maps 0 to 1, so that return 0; indicates successful termination. Other values are passed unchanged, so return 1; also indicates successful termination. EXIT_FAILURE would have a non-zero even value.)

You can use pandas.cut:

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

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

Or numpy.searchsorted:

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

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

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

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

By default cut return categorical.

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

Here's an example if:

ifeq ($(strip $(OS)),Linux)
        PYTHON = /usr/bin/python
        FIND = /usr/bin/find
endif

Note that this comes with a word of warning that different versions of Make have slightly different syntax, none of which seems to be documented very well.

Your problem is simple:

names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
  print (names)
end

This code first declares a global variable called names. Then, you start a for loop. The for loop declares a local variable that just happens to be called names too; the fact that a variable had previously been defined with names is entirely irrelevant. Any use of names inside the for loop will refer to the local one, not the global one.

The for loop says that the inner part of the loop will be called with names = 1, then names = 2, and finally names = 3. The for loop declares a counter that counts from the first number to the last, and it will call the inner code once for each value it counts.

What you actually wanted was something like this:

names = {'John', 'Joe', 'Steve'}
for nameCount = 1, 3 do
  print (names[nameCount])
end

The [] syntax is how you access the members of a Lua table. Lua tables map "keys" to "values". Your array automatically creates keys of integer type, which increase. So the key associated with "Joe" in the table is 2 (Lua indices always start at 1).

Therefore, you need a for loop that counts from 1 to 3, which you get. You use the count variable to access the element from the table.

However, this has a flaw. What happens if you remove one of the elements from the list?

names = {'John', 'Joe'}
for nameCount = 1, 3 do
  print (names[nameCount])
end

Now, we get John Joe nil, because attempting to access values from a table that don't exist results in nil. To prevent this, we need to count from 1 to the length of the table:

names = {'John', 'Joe'}
for nameCount = 1, #names do
  print (names[nameCount])
end

The # is the length operator. It works on tables and strings, returning the length of either. Now, no matter how large or small names gets, this will always work.

However, there is a more convenient way to iterate through an array of items:

names = {'John', 'Joe', 'Steve'}
for i, name in ipairs(names) do
  print (name)
end

ipairs is a Lua standard function that iterates over a list. This style of for loop, the iterator for loop, uses this kind of iterator function. The i value is the index of the entry in the array. The name value is the value at that index. So it basically does a lot of grunt work for you.

You can use

<?php the_category(', '); ?>

which would output them in a comma separated list.

You can also do the same for tags as well:

<?php the_tags('<em>:</em>', ', ', ''); ?>

CentOS Minimal usually install version 1.8 git by yum install gitcommand.

The best way is to build & install it from source code. Current version is 2.18.0.

1. Download the source code from https://mirrors.edge.kernel.org/pub/software/scm/git/ or curl -o git-2.18.0.tar.gz https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.18.0.tar.gz

2. Unzip by tar -zxf git-2.18.0.tar.gz && cd git-2.18.0

3. Install the dependency package by executing yum install autoconf curl-devel expat-devel gettext-devel openssl-devel perl-devel zlib-devel asciidoc xmlto openjade perl* texinfo

4. Install docbook2X, it's not in the rpm repository. Download and install by

   $ curl -o docbook2X-0.8.8-17.el7.x86_64.rpm http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/d/docbook2X-0.8.8-17.el7.x86_64.rpm $ rpm -Uvh docbook2X-0.8.8-17.el7.x86_64.rpm

And make a unix link name:

ln -s /usr/bin/db2x_docbook2texi /usr/bin/docbook2x-texi

5. Compile and install, reference to https://git-scm.com/book/en/v2/Getting-Started-Installing-Git

   $ make configure $ ./configure --prefix=/usr $ make all doc info $ sudo make install install-doc install-html install-info

6. Reboot your server (If not, you may encounter Unable to find remote helper for 'https' error)

   $ reboot now

I had a similar problem and it turned out the issue was having both versions 6 & 7 of OpenJDK. The answer comes from r-senior on ubuntu forums (http://ubuntuforums.org/showthread.php?t=1977619) --- just uninstall version 6:

sudo apt-get remove openjdk-6-*

make sure that JAVA_HOME and CLASSPATH aren't set to anything since that isn't actually the problem.

Since this is an old thread just adding an update:

To install the MySQL node.js driver:

If you run just npm install mysql, you need to be in the same directory that your run your server. I would advise to do it as in one of the following examples:

For global installation:

npm install -g mysql

For local installation:

1- Add it to your package.json in the dependencies:

"dependencies": {
    "mysql": "~2.3.2",
     ...

2- run npm install

Note that for connections to happen you will also need to be running the mysql server (which is node independent)

To install MySQL server:

There are a bunch of tutorials out there that explain this, and it is a bit dependent on operative system. Just go to google and search for how to install mysql server [Ubuntu|MacOSX|Windows]. But in a sentence: you have to go to http://www.mysql.com/downloads/ and install it.

If you have Microsoft Office installed, then you should be able to add a reference to Interop.Excel.

For example, the PC I'm typing this on has MSVS 2010 C# Express and Office 2010. I can add a reference to Microsoft.Office.Interop.Excel 11.0.0.0.

'Hope that helps

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

LATEST is deprecated, try with range [,)

./mvnw org.apache.maven.plugins:maven-dependency-plugin:3.1.1:get \  
-DremoteRepositories=repoId::default::https://nexus/repository/maven-releases/ \
"-Dartifact=com.acme:foo:[,)"

For this, what I did is

File f=new File("/data/data/your.app.package/databases/your_db.db3");
FileInputStream fis=null;
FileOutputStream fos=null;

try
{
  fis=new FileInputStream(f);
  fos=new FileOutputStream("/mnt/sdcard/db_dump.db");
  while(true)
  {
    int i=fis.read();
    if(i!=-1)
    {fos.write(i);}
    else
    {break;}
  }
  fos.flush();
  Toast.makeText(this, "DB dump OK", Toast.LENGTH_LONG).show();
}
catch(Exception e)
{
  e.printStackTrace();
  Toast.makeText(this, "DB dump ERROR", Toast.LENGTH_LONG).show();
}
finally
{
  try
  {
    fos.close();
    fis.close();
  }
  catch(IOException ioe)
  {}
}

And to do this, your app must have permission to access SD card, add following setting to your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Not a brilliant way, but works.

Most people will tell you to run this command:

mode con:cols=80 lines=100

but you should just try typing:

as a line in your batch file or cmd prompt.

using bootstrap 4 and SCSS check out this link here for full details

https://getbootstrap.com/docs/4.0/getting-started/theming/

in a nutshell...

open up lib/bootstrap/scss/_navbar.scss and find the statements that create these variables

  .navbar-nav {
    .nav-link {
      color: $navbar-light-color;

      @include hover-focus() {
        color: $navbar-light-hover-color;
      }

      &.disabled {
        color: $navbar-light-disabled-color;
      }
    }

so now you need to override

$navbar-light-color
$navbar-light-hover-color
$navbar-light-disabled-color

create a new scss file _localVariables.scss and add the following (with your colors)

$navbar-light-color : #520b71
$navbar-light-hover-color: #F3EFE6;
$navbar-light-disabled-color: #F3EFE6;

@import "../lib/bootstrap/scss/functions";
@import "../lib/bootstrap/scss/variables";
@import "../lib/bootstrap/scss/mixins/_breakpoints";

and on your other scss pages just add

@import "_localVariables";

instead of

@import "../lib/bootstrap/scss/functions";
@import "../lib/bootstrap/scss/variables";
@import "../lib/bootstrap/scss/mixins/_breakpoints";

SELECT SUBSTRING(subject, 1, 10) FROM tbl

You have a couple of things fighting in your strings.

• lack of correct MySQL quoting (mysql_real_escape_string())
• potential automatic 'magic quote' -- check your gpc_magic_quotes setting
• embedded string variables, which means you have to know how PHP correctly finds variables

It's also possible that the single-quoted value is not present in the parameters to the first query. Your example is a proper name, after all, and only the second query seems to be dealing with names.

java.time

Using the java.time framework built into Java 8 and later.

import java.time.Instant;

Instant.now().toEpochMilli(); //Long = 1450879900184
Instant.now().getEpochSecond(); //Long = 1450879900

This works in UTC because Instant.now() is really call to Clock.systemUTC().instant()

https://docs.oracle.com/javase/8/docs/api/java/time/Instant.html

As soon as you call contains, containsAll, equals, hashCode, remove, retainAll, size or toArray, you'd have to traverse the elements anyway.

If you're occasionally only calling methods such as isEmpty or clear I suppose you'd be better of by creating the collection lazily. You could for instance have a backing ArrayList for storing previously iterated elements.

I don't know of any such class in any library, but it should be a fairly simple exercise to write up.

1) My favorite:

git diff --name-status

Prepends file status, e.g.:

A   new_file.txt
M   modified_file.txt 
D   deleted_file.txt

2) If you want statistics, then:

git diff --stat

will show something like:

new_file.txt         |  50 +
modified_file.txt    | 100 +-
deleted_file         |  40 -

3) Finally, if you really want only the filenames:

git diff --name-only

Will simply show:

new_file.txt
modified_file.txt
deleted_file

Just Use: dataGridView1.CurrentCell.Value.ToString()

        private void dataGridView1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            MessageBox.Show(dataGridView1.CurrentCell.Value.ToString());
        }

or

 // dataGrid1.Rows[yourRowIndex ].Cells[yourColumnIndex].Value.ToString()

 //Example1:yourRowIndex=dataGridView1.CurrentRow.Index (from selectedRow );
 dataGrid1.Rows[dataGridView1.CurrentRow.Index].Cells[2].Value.ToString()

 //Example2:yourRowIndex=3,yourColumnIndex=2 (select by programmatically )
  dataGrid1.Rows[3].Cells[2].Value.ToString()

I use __get (and public properties) as much as possible, because they make code much more readable. Compare:

this code unequivocally says what i'm doing:

echo $user->name;

this code makes me feel stupid, which i don't enjoy:

function getName() { return $this->_name; }
....

echo $user->getName();

The difference between the two is particularly obvious when you access multiple properties at once.

echo "
    Dear $user->firstName $user->lastName!
    Your purchase:
        $product->name  $product->count x $product->price
"

and

echo "
    Dear " . $user->getFirstName() . " " . $user->getLastName() . "
    Your purchase: 
        " . $product->getName() . " " . $product->getCount() . "  x " . $product->getPrice() . " ";

Whether $a->b should really do something or just return a value is the responsibility of the callee. For the caller, $user->name and $user->accountBalance should look the same, although the latter may involve complicated calculations. In my data classes i use the following small method:

 function __get($p) { 
      $m = "get_$p";
      if(method_exists($this, $m)) return $this->$m();
      user_error("undefined property $p");
 }

when someone calls $obj->xxx and the class has get_xxx defined, this method will be implicitly called. So you can define a getter if you need it, while keeping your interface uniform and transparent. As an additional bonus this provides an elegant way to memorize calculations:

  function get_accountBalance() {
      $result = <...complex stuff...>
      // since we cache the result in a public property, the getter will be called only once
      $this->accountBalance = $result;
  }

  ....


   echo $user->accountBalance; // calculate the value
   ....
   echo $user->accountBalance; // use the cached value

Bottom line: php is a dynamic scripting language, use it that way, don't pretend you're doing Java or C#.

Since this is for Unix, the executables don't have any extensions.

One thing to note is that root-config is a utility which provides the right compilation and linking flags; and the right libraries for building applications against root. That's just a detail related to the original audience for this document.

Make Me Baby

or You Never Forget The First Time You Got Made

An introductory discussion of make, and how to write a simple makefile

What is Make? And Why Should I Care?

The tool called Make is a build dependency manager. That is, it takes care of knowing what commands need to be executed in what order to take your software project from a collection of source files, object files, libraries, headers, etc., etc.---some of which may have changed recently---and turning them into a correct up-to-date version of the program.

Actually, you can use Make for other things too, but I'm not going to talk about that.

A Trivial Makefile

Suppose that you have a directory containing: tool tool.cc tool.o support.cc support.hh, and support.o which depend on root and are supposed to be compiled into a program called tool, and suppose that you've been hacking on the source files (which means the existing tool is now out of date) and want to compile the program.

To do this yourself you could

1. Check if either support.cc or support.hh is newer than support.o, and if so run a command like

   g++ -g -c -pthread -I/sw/include/root support.cc
   

2. Check if either support.hh or tool.cc are newer than tool.o, and if so run a command like

   g++ -g  -c -pthread -I/sw/include/root tool.cc
   

3. Check if tool.o is newer than tool, and if so run a command like

   g++ -g tool.o support.o -L/sw/lib/root -lCore -lCint -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint \
   -lPostscript -lMatrix -lPhysics -lMathCore -lThread -lz -L/sw/lib -lfreetype -lz -Wl,-framework,CoreServices \
   -Wl,-framework,ApplicationServices -pthread -Wl,-rpath,/sw/lib/root -lm -ldl
   

Phew! What a hassle! There is a lot to remember and several chances to make mistakes. (BTW-- the particulars of the command lines exhibited here depend on our software environment. These ones work on my computer.)

Of course, you could just run all three commands every time. That would work, but it doesn't scale well to a substantial piece of software (like DOGS which takes more than 15 minutes to compile from the ground up on my MacBook).

Instead you could write a file called makefile like this:

tool: tool.o support.o
    g++ -g -o tool tool.o support.o -L/sw/lib/root -lCore -lCint -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint \
        -lPostscript -lMatrix -lPhysics -lMathCore -lThread -lz -L/sw/lib -lfreetype -lz -Wl,-framework,CoreServices \
        -Wl,-framework,ApplicationServices -pthread -Wl,-rpath,/sw/lib/root -lm -ldl

tool.o: tool.cc support.hh
    g++ -g  -c -pthread -I/sw/include/root tool.cc

support.o: support.hh support.cc
    g++ -g -c -pthread -I/sw/include/root support.cc

and just type make at the command line. Which will perform the three steps shown above automatically.

The unindented lines here have the form "target: dependencies" and tell Make that the associated commands (indented lines) should be run if any of the dependencies are newer than the target. That is, the dependency lines describe the logic of what needs to be rebuilt to accommodate changes in various files. If support.cc changes that means that support.o must be rebuilt, but tool.o can be left alone. When support.o changes tool must be rebuilt.

The commands associated with each dependency line are set off with a tab (see below) should modify the target (or at least touch it to update the modification time).

Variables, Built In Rules, and Other Goodies

At this point, our makefile is simply remembering the work that needs doing, but we still had to figure out and type each and every needed command in its entirety. It does not have to be that way: Make is a powerful language with variables, text manipulation functions, and a whole slew of built-in rules which can make this much easier for us.

Make Variables

The syntax for accessing a make variable is $(VAR).

The syntax for assigning to a Make variable is: VAR = A text value of some kind (or VAR := A different text value but ignore this for the moment).

You can use variables in rules like this improved version of our makefile:

CPPFLAGS=-g -pthread -I/sw/include/root
LDFLAGS=-g
LDLIBS=-L/sw/lib/root -lCore -lCint -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint \
       -lPostscript -lMatrix -lPhysics -lMathCore -lThread -lz -L/sw/lib -lfreetype -lz \
       -Wl,-framework,CoreServices -Wl,-framework,ApplicationServices -pthread -Wl,-rpath,/sw/lib/root \
       -lm -ldl

tool: tool.o support.o
    g++ $(LDFLAGS) -o tool tool.o support.o $(LDLIBS)

tool.o: tool.cc support.hh
    g++ $(CPPFLAGS) -c tool.cc

support.o: support.hh support.cc
    g++ $(CPPFLAGS) -c support.cc

which is a little more readable, but still requires a lot of typing

Make Functions

GNU make supports a variety of functions for accessing information from the filesystem or other commands on the system. In this case we are interested in $(shell ...) which expands to the output of the argument(s), and $(subst opat,npat,text) which replaces all instances of opat with npat in text.

Taking advantage of this gives us:

CPPFLAGS=-g $(shell root-config --cflags)
LDFLAGS=-g $(shell root-config --ldflags)
LDLIBS=$(shell root-config --libs)

SRCS=tool.cc support.cc
OBJS=$(subst .cc,.o,$(SRCS))

tool: $(OBJS)
    g++ $(LDFLAGS) -o tool $(OBJS) $(LDLIBS)

tool.o: tool.cc support.hh
    g++ $(CPPFLAGS) -c tool.cc

support.o: support.hh support.cc
    g++ $(CPPFLAGS) -c support.cc

which is easier to type and much more readable.

Notice that

1. We are still stating explicitly the dependencies for each object file and the final executable
2. We've had to explicitly type the compilation rule for both source files

Implicit and Pattern Rules

We would generally expect that all C++ source files should be treated the same way, and Make provides three ways to state this:

1. suffix rules (considered obsolete in GNU make, but kept for backwards compatibility)
2. implicit rules
3. pattern rules

Implicit rules are built in, and a few will be discussed below. Pattern rules are specified in a form like

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

which means that object files are generated from C source files by running the command shown, where the "automatic" variable $< expands to the name of the first dependency.

Built-in Rules

Make has a whole host of built-in rules that mean that very often, a project can be compile by a very simple makefile, indeed.

The GNU make built in rule for C source files is the one exhibited above. Similarly we create object files from C++ source files with a rule like $(CXX) -c $(CPPFLAGS) $(CFLAGS).

Single object files are linked using $(LD) $(LDFLAGS) n.o $(LOADLIBES) $(LDLIBS), but this won't work in our case, because we want to link multiple object files.

Variables Used By Built-in Rules

The built-in rules use a set of standard variables that allow you to specify local environment information (like where to find the ROOT include files) without re-writing all the rules. The ones most likely to be interesting to us are:

• CC -- the C compiler to use
• CXX -- the C++ compiler to use
• LD -- the linker to use
• CFLAGS -- compilation flag for C source files
• CXXFLAGS -- compilation flags for C++ source files
• CPPFLAGS -- flags for the c-preprocessor (typically include file paths and symbols defined on the command line), used by C and C++
• LDFLAGS -- linker flags
• LDLIBS -- libraries to link

A Basic Makefile

By taking advantage of the built-in rules we can simplify our makefile to:

CC=gcc
CXX=g++
RM=rm -f
CPPFLAGS=-g $(shell root-config --cflags)
LDFLAGS=-g $(shell root-config --ldflags)
LDLIBS=$(shell root-config --libs)

SRCS=tool.cc support.cc
OBJS=$(subst .cc,.o,$(SRCS))

all: tool

tool: $(OBJS)
    $(CXX) $(LDFLAGS) -o tool $(OBJS) $(LDLIBS)

tool.o: tool.cc support.hh

support.o: support.hh support.cc

clean:
    $(RM) $(OBJS)

distclean: clean
    $(RM) tool

We have also added several standard targets that perform special actions (like cleaning up the source directory).

Note that when make is invoked without an argument, it uses the first target found in the file (in this case all), but you can also name the target to get which is what makes make clean remove the object files in this case.

We still have all the dependencies hard-coded.

Some Mysterious Improvements

CC=gcc
CXX=g++
RM=rm -f
CPPFLAGS=-g $(shell root-config --cflags)
LDFLAGS=-g $(shell root-config --ldflags)
LDLIBS=$(shell root-config --libs)

SRCS=tool.cc support.cc
OBJS=$(subst .cc,.o,$(SRCS))

all: tool

tool: $(OBJS)
    $(CXX) $(LDFLAGS) -o tool $(OBJS) $(LDLIBS)

depend: .depend

.depend: $(SRCS)
    $(RM) ./.depend
    $(CXX) $(CPPFLAGS) -MM $^>>./.depend;

clean:
    $(RM) $(OBJS)

distclean: clean
    $(RM) *~ .depend

include .depend

Notice that

1. There are no longer any dependency lines for the source files!?!
2. There is some strange magic related to .depend and depend
3. If you do make then ls -A you see a file named .depend which contains things that look like make dependency lines

• Recursive Make Considered Harmful on a common way of writing makefiles that is less than optimal, and how to avoid it.

Know Bugs and Historical Notes

The input language for Make is whitespace sensitive. In particular, the action lines following dependencies must start with a tab. But a series of spaces can look the same (and indeed there are editors that will silently convert tabs to spaces or vice versa), which results in a Make file that looks right and still doesn't work. This was identified as a bug early on, but (the story goes) it was not fixed, because there were already 10 users.

_{(This was copied from a wiki post I wrote for physics graduate students.)}

Following Mike's answer, I'd also add another step. Let's imagine you have your data in column A.

• Insert a column with the word you want to add (column B, with k)
• apply the formula (as suggested by Mike) that merges both values in column C (C1=A1+B1)
• Copy down the formula
• Copy the values in column C (already merged)
• Paste special as 'values'
• Remove columns A and B

Hope it helps.

Ofc, if the word you want to add will always be the same, you won't need a column B (thus, C1="k"+A1)

VB (Visual Basic only up to 6.0) is a superset of VBA (Visual Basic for Applications). I know that others have sort of eluded to this but my understanding is that the semantics (i.e. the vocabulary) of VBA is included in VB6 (except for objects specific to Office products), therefore, VBA is a subset of VB6. The syntax (i.e. the order in which the words are written) is exactly the same in VBA as it would be in VB6, but the difference is the objects available to VBA or VB6 are different because they have different purposes. Specifically VBA's purpose is to programatically automate tasks that can be done in MS Office, whereas VB6's purpose is to create standard EXE, ActiveX Controls, ActiveX DLLs and ActiveX EXEs which can either work stand alone or in other programs such as MS Office or Windows.

Git 2.9.x/2.10 (Q3 2016) adds another debug option: GIT_TRACE_CURL.

See commit 73e57aa, commit 74c682d (23 May 2016) by Elia Pinto (devzero2000).
Helped-by: Torsten Bögershausen (tboegi), Ramsay Jones , Junio C Hamano (gitster), Eric Sunshine (sunshineco), and Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 2f84df2, 06 Jul 2016)}

http.c: implement the GIT_TRACE_CURL environment variable

Implement the GIT_TRACE_CURL environment variable to allow a greater degree of detail of GIT_CURL_VERBOSE, in particular the complete transport header and all the data payload exchanged.
It might be useful if a particular situation could require a more thorough debugging analysis.

The documentation will state:

GIT_TRACE_CURL

Enables a curl full trace dump of all incoming and outgoing data, including descriptive information, of the git transport protocol.
This is similar to doing curl --trace-ascii on the command line.

This option overrides setting the GIT_CURL_VERBOSE environment variable.

You can see that new option used in this answer, but also in the Git 2.11 (Q4 2016) tests:

See commit 14e2411, commit 81590bf, commit 4527aa1, commit 4eee6c6 (07 Sep 2016) by Elia Pinto (devzero2000).
^{(Merged by Junio C Hamano -- gitster -- in commit 930b67e, 12 Sep 2016)}

Use the new GIT_TRACE_CURL environment variable instead of the deprecated GIT_CURL_VERBOSE.

GIT_TRACE_CURL=true git clone --quiet $HTTPD_URL/smart/repo.git

Try this code:

$(document).ready(function(){
    $('#YourControlID').click(function(){
        if() { //your condition
            $.messager.show({  
                title:'My Title',  
                msg:'The message content',  
                showType:'fade',  
                style:{  
                    right:'',  
                    bottom:''  
                }  
            });  
        }
    });
});

Some programs can't process output stream very well, using pipe to Out-Null may not block it.
And Start-Process needs the -ArgumentList switch to pass arguments, not so convenient.
There is also another approach.

$exitCode = [Diagnostics.Process]::Start(<process>,<arguments>).WaitForExit(<timeout>)

You can choose the url where the form must be posted (and thus, the invoked action) in different ways, depending on the browser support:

• for newer browsers that support HTML5, you can use formaction attribute of a submit button
• for older browsers that don't support this, you need to use some JavaScript that changes the form's action attribute, when the button is clicked, and before submitting

In this way you don't need to do anything special on the server side.

Of course, you can use Url extensions methods in your Razor to specify the form action.

For browsers supporting HMTL5: simply define your submit buttons like this:

<input type='submit' value='...' formaction='@Url.Action(...)' />

For older browsers I recommend using an unobtrusive script like this (include it in your "master layout"):

$(document).on('click', '[type="submit"][data-form-action]', function (event) {
  var $this = $(this);
  var formAction = $this.attr('data-form-action');
  $this.closest('form').attr('action', formAction);
});

NOTE: This script will handle the click for any element in the page that has type=submit and data-form-action attributes. When this happens, it takes the value of data-form-action attribute and set the containing form's action to the value of this attribute. As it's a delegated event, it will work even for HTML loaded using AJAX, without taking extra steps.

Then you simply have to add a data-form-action attribute with the desired action URL to your button, like this:

<input type='submit' data-form-action='@Url.Action(...)' value='...'/>

Note that clicking the button changes the form's action, and, right after that, the browser posts the form to the desired action.

As you can see, this requires no custom routing, you can use the standard Url extension methods, and you have nothing special to do in modern browsers.

If a task faults, the exception is re-thrown when the continuation code calls awaiter.GetResult(). Rather than calling GetResult, we could simply access the Result property of the task. The benefit of calling GetResult is that if the task faults, the exception is thrown directly without being wrapped in AggregateException, allowing for simpler and cleaner catch blocks.

For nongeneric tasks, GetResult() has a void return value. Its useful function is then solely to rethrow exceptions.

DataRow dataRow = dataTable.AsEnumerable().FirstOrDefault(r => Convert.ToInt32(r["ID"]) == 5);
if (dataRow != null)
{
    // code

If it is a typed DataSet:

MyDatasetType.MyDataTableRow dataRow = dataSet.MyDataTable.FirstOrDefault(r => r.ID == 5);
if (dataRow != null)
{
    // code
}

In 3.5, Python finally got a matrix multiplication operator. The syntax is a @ b.

The sessions on PHP works with a Cookie type session, while on server-side the session information is constantly deleted.

For set the time life in php, you can use the function session_set_cookie_params, before the session_start:

session_set_cookie_params(3600,"/");
session_start();

For ex, 3600 seconds is one hour, for 2 hours 3600*2 = 7200.

But it is session cookie, the browser can expire it by itself, if you want to save large time sessions (like remember login), you need to save the data in the server and a standard cookie in the client side.

You can have a Table "Sessions":

• session_id int
• session_hash varchar(20)
• session_data text

And validating a Cookie, you save the "session id" and the "hash" (for security) on client side, and you can save the session's data on the server side, ex:

On login:

setcookie('sessid', $sessionid, 604800);      // One week or seven days
setcookie('sesshash', $sessionhash, 604800);  // One week or seven days
// And save the session data:
saveSessionData($sessionid, $sessionhash, serialize($_SESSION)); // saveSessionData is your function

If the user return:

if (isset($_COOKIE['sessid'])) {
    if (valide_session($_COOKIE['sessid'], $_COOKIE['sesshash'])) {
        $_SESSION = unserialize(get_session_data($_COOKIE['sessid']));
    } else {
        // Dont validate the hash, possible session falsification
    }
}

Obviously, save all session/cookies calls, before sending data.

You don't really need to use Singleton pattern because it's considered to be an antipattern. Basically there is a lot of reasons to not to implement this pattern at all. Read this to start with: Best practice on PHP singleton classes.

If after all you still think you need to use Singleton pattern then we could write a class that will allow us to get Singleton functionality by extending our SingletonClassVendor abstract class.

This is what I came with to solve this problem.

<?php
namespace wl;


/**
 * @author DevWL
 * @dosc allows only one instance for each extending class.
 * it acts a litle bit as registry from the SingletonClassVendor abstract class point of view
 * but it provides a valid singleton behaviour for its children classes
 * Be aware, the singleton pattern is consider to be an anti-pattern
 * mostly because it can be hard to debug and it comes with some limitations.
 * In most cases you do not need to use singleton pattern
 * so take a longer moment to think about it before you use it.
 */
abstract class SingletonClassVendor
{
    /**
     *  holds an single instance of the child class
     *
     *  @var array of objects
     */
    protected static $instance = [];

    /**
     *  @desc provides a single slot to hold an instance interchanble between all child classes.
     *  @return object
     */
    public static final function getInstance(){
        $class = get_called_class(); // or get_class(new static());
        if(!isset(self::$instance[$class]) || !self::$instance[$class] instanceof $class){
            self::$instance[$class] = new static(); // create and instance of child class which extends Singleton super class
            echo "new ". $class . PHP_EOL; // remove this line after testing
            return  self::$instance[$class]; // remove this line after testing
        }
        echo "old ". $class . PHP_EOL; // remove this line after testing
        return static::$instance[$class];
    }

    /**
     * Make constructor abstract to force protected implementation of the __constructor() method, so that nobody can call directly "new Class()".
     */
    abstract protected function __construct();

    /**
     * Make clone magic method private, so nobody can clone instance.
     */
    private function __clone() {}

    /**
     * Make sleep magic method private, so nobody can serialize instance.
     */
    private function __sleep() {}

    /**
     * Make wakeup magic method private, so nobody can unserialize instance.
     */
    private function __wakeup() {}

}

Use example:

/**
 * EXAMPLE
 */

/**
 *  @example 1 - Database class by extending SingletonClassVendor abstract class becomes fully functional singleton
 *  __constructor must be set to protected becaouse: 
 *   1 to allow instansiation from parent class 
 *   2 to prevent direct instanciation of object with "new" keword.
 *   3 to meet requierments of SingletonClassVendor abstract class
 */
class Database extends SingletonClassVendor
{
    public $type = "SomeClass";
    protected function __construct(){
        echo "DDDDDDDDD". PHP_EOL; // remove this line after testing
    }
}


/**
 *  @example 2 - Config ...
 */
class Config extends SingletonClassVendor
{
    public $name = "Config";
    protected function __construct(){
        echo "CCCCCCCCCC" . PHP_EOL; // remove this line after testing
    }
}

Just to prove that it works as expected:

/**
 *  TESTING
 */
$bd1 = Database::getInstance(); // new
$bd2 = Database::getInstance(); // old
$bd3 = Config::getInstance(); // new
$bd4 = Config::getInstance(); // old
$bd5 = Config::getInstance(); // old
$bd6 = Database::getInstance(); // old
$bd7 = Database::getInstance(); // old
$bd8 = Config::getInstance(); // old

echo PHP_EOL."COMPARE ALL DATABASE INSTANCES".PHP_EOL;
var_dump($bd1);
echo '$bd1 === $bd2' . ($bd1 === $bd2)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd2 === $bd6' . ($bd2 === $bd6)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd6 === $bd7' . ($bd6 === $bd7)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE

echo PHP_EOL;

echo PHP_EOL."COMPARE ALL CONFIG INSTANCES". PHP_EOL;
var_dump($bd3);
echo '$bd3 === $bd4' . ($bd3 === $bd4)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd4 === $bd5' . ($bd4 === $bd5)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE
echo '$bd5 === $bd8' . ($bd5 === $bd8)? ' TRUE' . PHP_EOL: ' FALSE' . PHP_EOL; // TRUE

This worked for me.

You need to run it twice once for globals followed by locals

for name in dir():
    if not name.startswith('_'):
        del globals()[name]

for name in dir():
    if not name.startswith('_'):
        del locals()[name]

<a href="https://www." style="color: inherit;"target="_blank">

For CSS inline style, this worked best for me.

With numpy 1.3 or svn you can do this

In [1]: a = arange(10000.).reshape(100,100)

In [3]: isnan(a.max())
Out[3]: False

In [4]: a[50,50] = nan

In [5]: isnan(a.max())
Out[5]: True

In [6]: timeit isnan(a.max())
10000 loops, best of 3: 66.3 µs per loop

The treatment of nans in comparisons was not consistent in earlier versions.

Add this class css to your style sheet

.border_gradient {
border: 8px solid #000;
-moz-border-bottom-colors:#897048 #917953 #a18a66 #b6a488 #c5b59b #d4c5ae #e2d6c4 #eae1d2;
-moz-border-top-colors:#897048 #917953 #a18a66 #b6a488 #c5b59b #d4c5ae #e2d6c4 #eae1d2;
-moz-border-left-colors:#897048 #917953 #a18a66 #b6a488 #c5b59b #d4c5ae #e2d6c4 #eae1d2;
-moz-border-right-colors:#897048 #917953 #a18a66 #b6a488 #c5b59b #d4c5ae #e2d6c4 #eae1d2;
padding: 5px 5px 5px 15px;
width: 300px;
}

set width to the width of your image. and use this html for image

<div class="border_gradient">
        <img src="image.png" />
</div>

though it may not give the same exact border, it will some gradient looks on the border.

Try adding this to your where clause:

dateadd(day, -30, getdate())

Execute is sql*plus syntax .. try wrapping your call in begin .. end like this:

begin 
    temp_proc;
end;

(Although Jeffrey says this doesn't work in APEX .. but you're trying to get this to run in SQLDeveloper .. try the 'Run' menu there.)

Inspired from @Hamed, I added the following and it worked for me:

display: inline-block; overflow: hidden; 

you can use this to get the data of the last 30 days based on a column.

WHERE DATEDIFF(dateColumn,CURRENT_TIMESTAMP) BETWEEN 0 AND 30

This will be helpful for the right bottom rounded button

HTML :

      <a class="fixedButton" href>
         <div class="roundedFixedBtn"><i class="fa fa-phone"></i></div>
      </a>
    

CSS:

       .fixedButton{
            position: fixed;
            bottom: 0px;
            right: 0px; 
            padding: 20px;
        }
        .roundedFixedBtn{
          height: 60px;
          line-height: 80px;  
          width: 60px;  
          font-size: 2em;
          font-weight: bold;
          border-radius: 50%;
          background-color: #4CAF50;
          color: white;
          text-align: center;
          cursor: pointer;
        }

I wrote a library to handle android recycler view item click event. You can find whole tutorial in https://github.com/ChathuraHettiarachchi/RecycleClick

RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemClickListener(new RecycleClick.OnItemClickListener() {
            @Override
            public void onItemClicked(RecyclerView recyclerView, int position, View v) {
                // YOUR CODE
            }
        });

or to handle item long press you can use

RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemLongClickListener(new RecycleClick.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClicked(RecyclerView recyclerView, int position, View v) {
                // YOUR CODE
                return true;
            }
        });

//declaration 
list: Array<any> = new Array<any>(); 

//remove item from an array 
removeitem() 
{
const index = this.list.findIndex(user => user._id === 2); 
this.list.splice(index, 1); 
}

I'm a bit newer to Angular but what I found useful to do (and pretty simple) is I made a global script that I load onto my page before the local script with global variables that I need to access on all pages anyway. In that script, I created an object called "globalFunctions" and added the functions that I need to access globally as properties. e.g. globalFunctions.foo = myFunc();. Then, in each local script, I wrote $scope.globalFunctions = globalFunctions; and I instantly have access to any function I added to the globalFunctions object in the global script.

This is a bit of a workaround and I'm not sure it helps you but it definitely helped me as I had many functions and it was a pain adding all of them to each page.

For boot2docker, we can set it on /var/lib/boot2docker/profile, for instance:

ulimit -n 2018

Be warned not to set this limit too high as it will slow down apt-get! See bug #1332440. I had it with debian jessie.

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

Further reference about trusting save values

Follow this steps:

-Build
-Generate Signed Apk
-Create new

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

Each application pool in IIs creates its own secure user folder with FULL read/write permission by default under c:\users. Open up your Users folder and see what application pool folders are there, right click, and check their rights for the application pool virtual account assigned. You should see your application pool account added already with read/write access assigned to its root and subfolders.

So that type of file storage access is automatically done and you should be able to write whatever you like there in the app pools user account folders without changing anything. That's why virtual user accounts for each application pool were created.

You could change SelectedIndex property:

comboBox1.SelectedIndex = -1;

This is a workaround (for me: I don't use awk very often):

Display the first row of the file containing the data, replace all pipes with newlines and then count the lines:

$ head -1 stores.dat | tr '|' '\n' | wc -l

Have you tried with prop() ??

Well prop() seems works for me.

You need a different seed at every execution.

You can start to call at the beginning of your program:

srand(time(NULL));

Note that % 10 yields a result from 0 to 9 and not from 1 to 10: just add 1 to your % expression to get 1 to 10.

Additionally Remember, Don't forget to add public keyword like this

[Key] 
int RoleId { get; set; } //wrong method

you must use Public keyword like this

[Key] 
public int RoleId { get; set; } //correct method

As per this link you may also have to prefix your param with &rp if not using proxy syntax

Postgres Enterprise Manager from EnterpriseDB is probably the most advanced you'll find. It includes all the features of pgAdmin, plus monitoring of your hosts and database servers, predictive reporting, alerting and a SQL Profiler.

Ninja edit disclaimer/notice: it seems that this user is affiliated with EnterpriseDB, as the linked Postgres Enterprise Manager website contains a video of one Dave Page.

Maybe this small Typescript code example will help.

private getAccount(id: Id) : Account {
    let account = Account.empty();
    this.repository.get(id)
        .then(res => account = res)
        .catch(e => Notices.results(e));
    return account;
}

Here the repository.get(id) returns a Promise<Account>. I assign it to the variable account within the then statement.

Simple:

homestead destroy
homestead up

Edit (Not as simple as first thought):

The issue was that new versions of homestead use php7.0 and some other stuff. To avoid this mess up make sure you set the verison in Homestead.yml:

version: "0"

There is a trick that always worked for me:

If you got and unexpected indent and you see that all the code is perfectly indented, try opening it with another editor and you will see what line of code is not indented.

It happened to me when used vim, gedit or editors like that.

Try to use only 1 editor for your code.

The "image" people generally show during an ajax call is an animated gif. Since there is no way to determine the percent complete of the ajax request, the animated gifs used are indeterminate spinners. This is just an image repeating over and over like a ball of circles of varying sizes. A good site to create your own custom indeterminate spinner is http://ajaxload.info/

Convert timeofday to string to use indexOf

var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;
console.log(typeof(timeofday)) // for testing will log number
function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)
    var pos = time.indexOf('.');
    var hrs = time.substr(1, pos - 1);
    var min = (time.substr(pos, 2)) * 60;

    if (hrs > 11) {
        hrs = (hrs - 12) + ":" + min + " PM";
    } else {
        hrs += ":" + min + " AM";
    }
    return hrs;
}
 // "" for typecasting to string
 document.getElementById("oset").innerHTML = timeD2C(""+timeofday);

Test Here

Solution 2

use toString() to convert to string

document.getElementById("oset").innerHTML = timeD2C(timeofday.toString());

jsfiddle with toString()

You can either give class name to all label so that all can have same width :

 .class-name {  width:200px;}

Example

.labelname{  width:200px;}

or you can simple give rest of label

label {  width:200px;  display: inline-block;}

Another way to pass named parameters to Bash... is passing by reference. This is supported as of Bash 4.0

#!/bin/bash
function myBackupFunction(){ # directory options destination filename
local directory="$1" options="$2" destination="$3" filename="$4";
  echo "tar cz ${!options} ${!directory} | ssh root@backupserver \"cat > /mnt/${!destination}/${!filename}.tgz\"";
}

declare -A backup=([directory]=".." [options]="..." [destination]="backups" [filename]="backup" );

myBackupFunction backup[directory] backup[options] backup[destination] backup[filename];

An alternative syntax for Bash 4.3 is using a nameref.

Although the nameref is a lot more convenient in that it seamlessly dereferences, some older supported distros still ship an older version, so I won't recommend it quite yet.

Neither of the codes work for me, so I use this instead for months and days:

function monthDiff(d2, d1) {
    var months;
    months = (d2.getFullYear() - d1.getFullYear()) * 12;
    months -= d1.getMonth() + 1;
    months += d2.getMonth() + 1;
    return months <= 0 ? 0 : months;
}

function daysInMonth(date) {
    return new Date(date.getYear(), date.getMonth() + 1, 0).getDate();
}    

function diffDate(date1, date2) {
    if (date2 && date2.getTime() && !isNaN(date2.getTime())) {
        var months = monthDiff(date1, date2);
        var days = 0;

        if (date1.getUTCDate() >= date2.getUTCDate()) {
            days = date1.getUTCDate() - date2.getUTCDate();
        }
        else {
            months--;
            days = date1.getUTCDate() - date2.getUTCDate() + daysInMonth(date2);
        }

        // Use the variables months and days how you need them.
    }
}

It may also be usefull to understand the difference in term of Session Bean Identity when using @EJB and @Inject. According to the specifications the following code will always be true:

@EJB Cart cart1;
@EJB Cart cart2;
… if (cart1.equals(cart2)) { // this test must return true ...}

Using @Inject instead of @EJB there is not the same.

see also stateless session beans identity for further info

The safest way IMO is to point at the file in your run/debug config

-Dlog4j.configuration=file:mylogging.properties

! Be aware: when using the eclipse launch configurations the specification of the file: protocol is mandatory.

In this way the logger will not catch any logging.properties that come before in the classpath nor the default one in the JDK.

Also, consider actually use the log4j.xml which has a richer expression syntax and will allow more things (log4j.xml tahe precedence over log4j.properties.

MyEmail.Body = string.Format("The validation is done at {0:HH:mm:ss} Hrs.",DateTime.Now);

Can Use {0:HH:mm:ss}, {0:HH:mm:ss.fff}, {0:DD/mm/yyy HH:mm:ss}, etc...

function get_col_names(){  
    $sql = "SHOW COLUMNS FROM tableName";  
    $result = mysql_query($sql);     
    while($record = mysql_fetch_array($result)){  
     $fields[] = $record['0'];  
    }
    foreach ($fields as $value){  
      echo 'column name is : '.$value.'-';  
}  
 }  

return get_col_names();

The differences between an Abstract Class and an Interface:

Abstract Classes

An abstract class can provide some functionality and leave the rest for derived class.

• The derived class may or may not override the concrete functions defined in the base class.

• A child class extended from an abstract class should logically be related.

Interface

An interface cannot contain any functionality. It only contains definitions of the methods.

• The derived class MUST provide code for all the methods defined in the interface.

• Completely different and non-related classes can be logically grouped together using an interface.

I had the same problem, with version 3.4.2

to run it (if you installed it with homebrew) run the process like this:

$ mongod --dbpath /usr/local/var/mongodb

here is the easiest way to add progress bar in android Web View.

Add a boolean field in your activity/fragment

private boolean isRedirected;

This boolean will prevent redirection of web pages cause of dead links.Now you can just pass your WebView object and web Url into this method.

private void startWebView(WebView webView,String url) {

    webView.setWebViewClient(new WebViewClient() {
        ProgressDialog progressDialog;

        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            isRedirected = true;
            return false;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            isRedirected = false;
        }

        public void onLoadResource (WebView view, String url) {
            if (!isRedirected) {
                if (progressDialog == null) {
                    progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                    progressDialog.setMessage("Loading...");
                    progressDialog.show();
                }
            }

        }
        public void onPageFinished(WebView view, String url) {
            try{
                isRedirected=true;

                if (progressDialog.isShowing()) {
                    progressDialog.dismiss();
                    progressDialog = null;
                }



            }catch(Exception exception){
                exception.printStackTrace();
            }
        }

    });

    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(url);
}

Here when start loading it will call onPageStarted. Here i setting Boolean field is false. But when page load finish it will come to onPageFinished method and here Boolean field is set to true. Sometimes if url is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason it will not hiding the progress bar. To prevent this i am checking if (!isRedirected) in onLoadResource()

in onPageFinished() method before dismissing the Progress Dialog you can write your 10 second time delay code

That's it. Happy coding :)
