Stephen Colebourne has created a proposal for adding multi-line strings in Java 7.

Also, Groovy already has support for multi-line strings.

Your error is in resultCode = Activity.RESULT_CANCELED, you should instance like resultCode == Activity.RESULT_CANCELED ==

An Android Context is an Interface (in the general sense, not in the Java sense; in Java, Context is actually an abstract class!) that allows access to application specific resources and class and information about application environment.

If your android app was a web app, your context would be something similar to ServletContext (I am not making an exact comparison here).

Your activities and services also extend Context, so they inherit all those methods to access the environment information in which the app is running.

To literally fix your example you would use this:

Sub Normalize()


    Dim Ticker As Range
    Sheets("Sheet1").Activate
    Set Ticker = Range(Cells(2, 1), Cells(65, 1))
    Ticker.Copy

    Sheets("Sheet2").Select
    Cells(1, 1).PasteSpecial xlPasteAll



End Sub

To Make slight improvments on it would be to get rid of the Select and Activates:

Sub Normalize()
    With Sheets("Sheet1")
        .Range(.Cells(2, 1), .Cells(65, 1)).Copy Sheets("Sheet2").Cells(1, 1)
    End With
End Sub

but using the clipboard takes time and resources so the best way would be to avoid a copy and paste and just set the values equal to what you want.

Sub Normalize()
Dim CopyFrom As Range

Set CopyFrom = Sheets("Sheet1").Range("A2", [A65])
Sheets("Sheet2").Range("A1").Resize(CopyFrom.Rows.Count).Value = CopyFrom.Value

End Sub

To define the CopyFrom you can use anything you want to define the range, You could use Range("A2:A65"), Range("A2",[A65]), Range("A2", "A65") all would be valid entries. also if the A2:A65 Will never change the code could be further simplified to:

Sub Normalize()

Sheets("Sheet2").Range("A1:A65").Value = Sheets("Sheet1").Range("A2:A66").Value

End Sub

I added the Copy from range, and the Resize property to make it slightly more dynamic in case you had other ranges you wanted to use in the future.

If you have a request going to an application in the site, make sure you set maxRequestLength in the root web.config. The maxRequestLength in the applications's web.config appears to be ignored.

You shouldn't use strcpy() to copy a std::string, only use it for C-Style strings.

If you want to copy a to b then just use the = operator.

string a = "text";
string b = "image";
b = a;

try putting a delay on the last color fade.

$("p#44.test").delay(3000).css("background-color","red");

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!

If you use Firebug, you can use console.log to output an object and get a hyperlinked, explorable item in the console.

swift solution

yourlabel.text = yourvariable

or self is use for when you are in async {brackets} or in some Extension

DispatchQueue.main.async{
    self.yourlabel.text = "typestring"
}

As Geoff says, what Crockford says is good.

The only exception I follow (and have seen widely used) is to use $varname to indicate a jQuery (or whatever library) object. E.g.

var footer = document.getElementById('footer');

var $footer = $('#footer');

Option 1

If you do not need to use Authentication you can add configs to ngrok commands

ngrok http 9000 --host-header=rewrite

or

ngrok http 9000 --host-header="localhost:9000"

But in this case Authentication will not work on your website because ngrok rewriting headers and session is not valid for your ngrok domain

Option 2

If you are using webpack you can add the following configuration

devServer: {
    disableHostCheck: true
}

In that case Authentication header will be valid for your ngrok domain

Load the following up needed script in the callback of the previous one like:

$.getScript('scripta.js', function()
{
   $.getScript('scriptb.js', function()
   {
       // run script that depends on scripta.js and scriptb.js
   });
});

$("span").mouseover(function () {
$(this).css({"background-color":"green","font-size":"20px","color":"red"});
});

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html

e.g.:

imageView.setImageResource(R.drawable.myimage);

use grep [n]ame to remove that grep -v name this is first... Sec using xargs in the way how it is up there is wrong to rnu whatever it is piped you have to use -i ( interactive mode) otherwise you may have issues with the command.

ps axf | grep | grep -v grep | awk '{print "kill -9 " $1}' ? ps aux |grep [n]ame | awk '{print "kill -9 " $2}' ? isnt that better ?

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

The Data Export function in MySQL Workbench allows 2 of the 3 ways. There's a checkbox Skip Table Data (no-data) on the export page which allows to either dump with or without data. Just dumping the data without meta data is not supported.

Since some of the other answers include info on rebuilding, and my use case also required a rebuild, I had a better solution (compared to those).

There's still a way to easily target just the one single worker container that both rebuilds + restarts it in a single line, albeit it's not actually a single command. The best solution for me was simply rebuild and restart:

docker-compose build worker && docker-compose restart worker

This accomplishes both major goals at once for me:

1. Targets the single worker container
2. Rebuilds and restarts it in a single line

Hope this helps anyone else getting here.

DataFrame's read_excel method is like read_csv method:

dfs = pd.read_excel(xlsx_file, sheetname="sheet1")


Help on function read_excel in module pandas.io.excel:

read_excel(io, sheetname=0, header=0, skiprows=None, skip_footer=0, index_col=None, names=None, parse_cols=None, parse_dates=False, date_parser=None, na_values=None, thousands=None, convert_float=True, has_index_names=None, converters=None, true_values=None, false_values=None, engine=None, squeeze=False, **kwds)
    Read an Excel table into a pandas DataFrame

    Parameters
    ----------
    io : string, path object (pathlib.Path or py._path.local.LocalPath),
        file-like object, pandas ExcelFile, or xlrd workbook.
        The string could be a URL. Valid URL schemes include http, ftp, s3,
        and file. For file URLs, a host is expected. For instance, a local
        file could be file://localhost/path/to/workbook.xlsx
    sheetname : string, int, mixed list of strings/ints, or None, default 0

        Strings are used for sheet names, Integers are used in zero-indexed
        sheet positions.

        Lists of strings/integers are used to request multiple sheets.

        Specify None to get all sheets.

        str|int -> DataFrame is returned.
        list|None -> Dict of DataFrames is returned, with keys representing
        sheets.

        Available Cases

        * Defaults to 0 -> 1st sheet as a DataFrame
        * 1 -> 2nd sheet as a DataFrame
        * "Sheet1" -> 1st sheet as a DataFrame
        * [0,1,"Sheet5"] -> 1st, 2nd & 5th sheet as a dictionary of DataFrames
        * None -> All sheets as a dictionary of DataFrames

    header : int, list of ints, default 0
        Row (0-indexed) to use for the column labels of the parsed
        DataFrame. If a list of integers is passed those row positions will
        be combined into a ``MultiIndex``
    skiprows : list-like
        Rows to skip at the beginning (0-indexed)
    skip_footer : int, default 0
        Rows at the end to skip (0-indexed)
    index_col : int, list of ints, default None
        Column (0-indexed) to use as the row labels of the DataFrame.
        Pass None if there is no such column.  If a list is passed,
        those columns will be combined into a ``MultiIndex``
    names : array-like, default None
        List of column names to use. If file contains no header row,
        then you should explicitly pass header=None
    converters : dict, default None
        Dict of functions for converting values in certain columns. Keys can
        either be integers or column labels, values are functions that take one
        input argument, the Excel cell content, and return the transformed
        content.
    true_values : list, default None
        Values to consider as True

        .. versionadded:: 0.19.0

    false_values : list, default None
        Values to consider as False

        .. versionadded:: 0.19.0

    parse_cols : int or list, default None
        * If None then parse all columns,
        * If int then indicates last column to be parsed
        * If list of ints then indicates list of column numbers to be parsed
        * If string then indicates comma separated list of column names and
          column ranges (e.g. "A:E" or "A,C,E:F")
    squeeze : boolean, default False
        If the parsed data only contains one column then return a Series
    na_values : scalar, str, list-like, or dict, default None
        Additional strings to recognize as NA/NaN. If dict passed, specific
        per-column NA values. By default the following values are interpreted
        as NaN: '', '#N/A', '#N/A N/A', '#NA', '-1.#IND', '-1.#QNAN', '-NaN', '-nan',
    '1.#IND', '1.#QNAN', 'N/A', 'NA', 'NULL', 'NaN', 'nan'.
    thousands : str, default None
        Thousands separator for parsing string columns to numeric.  Note that
        this parameter is only necessary for columns stored as TEXT in Excel,
        any numeric columns will automatically be parsed, regardless of display
        format.
    keep_default_na : bool, default True
        If na_values are specified and keep_default_na is False the default NaN
        values are overridden, otherwise they're appended to.
    verbose : boolean, default False
        Indicate number of NA values placed in non-numeric columns
    engine: string, default None
        If io is not a buffer or path, this must be set to identify io.
        Acceptable values are None or xlrd
    convert_float : boolean, default True
        convert integral floats to int (i.e., 1.0 --> 1). If False, all numeric
        data will be read in as floats: Excel stores all numbers as floats
        internally
    has_index_names : boolean, default None
        DEPRECATED: for version 0.17+ index names will be automatically
        inferred based on index_col.  To read Excel output from 0.16.2 and
        prior that had saved index names, use True.

    Returns
    -------
    parsed : DataFrame or Dict of DataFrames
        DataFrame from the passed in Excel file.  See notes in sheetname
        argument for more information on when a Dict of Dataframes is returned.

I've had a similar requirement: I needed to inject a Spring-managed repository bean into my Person entity class ("entity" as in "something with an identity", for example an JPA entity). A Person instance has friends, and for this Person instance to return its friends, it shall delegate to its repository and query for friends there.

@Entity
public class Person {
    private static PersonRepository personRepository;

    @Id
    @GeneratedValue
    private long id;

    public static void setPersonRepository(PersonRepository personRepository){
        this.personRepository = personRepository;
    }

    public Set<Person> getFriends(){
        return personRepository.getFriends(id);
    }

    ...
}

.

@Repository
public class PersonRepository {

    public Person get Person(long id) {
        // do database-related stuff
    }

    public Set<Person> getFriends(long id) {
        // do database-related stuff
    }

    ...
}

So how did I inject that PersonRepository singleton into the static field of the Person class?

I created a @Configuration, which gets picked up at Spring ApplicationContext construction time. This @Configuration gets injected with all those beans that I need to inject as static fields into other classes. Then with a @PostConstruct annotation, I catch a hook to do all static field injection logic.

@Configuration
public class StaticFieldInjectionConfiguration {

    @Inject
    private PersonRepository personRepository;

    @PostConstruct
    private void init() {
        Person.setPersonRepository(personRepository);
    }
}

if(!empty($youtube) && empty($link)) {

}
else if(empty($youtube) && !empty($link)) {

}
else if(empty($youtube) && empty($link)) {
}

How I solved my problem.

I had

?useUnicode=true&characterEncoding=UTF-8

In my hibernate jdbc connection url and I changed the string datatype to longtext in database, which was varchar before.

You just have to change the structure of the if...else..endif somewhat:

if exists(select * from Table where FieldValue='') then begin
  select TableID from Table where FieldValue=''
end else begin
  insert into Table (FieldValue) values ('')
  select TableID from Table where TableID = scope_identity()
end

You could also do:

if not exists(select * from Table where FieldValue='') then begin
  insert into Table (FieldValue) values ('')
end
select TableID from Table where FieldValue=''

Or:

if exists(select * from Table where FieldValue='') then begin
  select TableID from Table where FieldValue=''
end else begin
  insert into Table (FieldValue) values ('')
  select scope_identity() as TableID
end

test.xml:

<?xml version="1.0" encoding="utf-8"?>
<Contacts>
  <Node>
    <ID>123</ID>
    <Name>ABC</Name>
  </Node>
  <Node>
    <ID>124</ID>
    <Name>DEF</Name>
  </Node>
</Contacts>

Select a single node:

XDocument XMLDoc = XDocument.Load("test.xml");
string id = "123"; // id to be selected

XElement Contact = (from xml2 in XMLDoc.Descendants("Node")
                    where xml2.Element("ID").Value == id
                    select xml2).FirstOrDefault();

Console.WriteLine(Contact.ToString());

Delete a single node:

XDocument XMLDoc = XDocument.Load("test.xml");
string id = "123";

var Contact = (from xml2 in XMLDoc.Descendants("Node")
               where xml2.Element("ID").Value == id
               select xml2).FirstOrDefault();

Contact.Remove();
XMLDoc.Save("test.xml");

Add new node:

XDocument XMLDoc = XDocument.Load("test.xml");

XElement newNode = new XElement("Node",
    new XElement("ID", "500"),
    new XElement("Name", "Whatever")
);

XMLDoc.Element("Contacts").Add(newNode);
XMLDoc.Save("test.xml");

Thanks @Ole V.v for reviewing it: i have found some inbuilt library classes which does the same

    int noOfMonths = 0;
    org.joda.time.format.DateTimeFormatter formatter = DateTimeFormat
            .forPattern("yyyy-MM-dd");
    DateTime dt = formatter.parseDateTime(startDate);

    DateTime endDate11 = new DateTime();
    Months m = Months.monthsBetween(dt, endDate11);
    noOfMonths = m.getMonths();
    System.out.println(noOfMonths);

If you need to display your variable unescaped, use this format:

<script th:inline="javascript">
/*<![CDATA[*/

    var message = /*[(${message})]*/ 'default';

/*]]>*/
</script>

Note the [( brackets which wrap the variable.

This is the one I use:

    return ''

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

Similarly for all parts of the if condition.

proper way to do this :

try{
    if( !process_x() ){
        throw new Exception('process_x failed');
    }

    /* do a lot of other things */

    if( !process_y() ){
        throw new Exception('process_y failed');
    }

    /* do a lot of other things */

    if( !process_z() ){
        throw new Exception('process_z failed');
    }

    /* do a lot of other things */
    /* SUCCESS */
}catch(Exception $ex){
    clean_all_processes();
}

After reading some of the comments, I realized that exception handling doesn't always makes sense for normal flow control. For normal control flow it is better to use "If else":

try{
  if( process_x() && process_y() && process_z() ) {
    // all processes successful
    // do something
  } else {
    //one of the processes failed
    clean_all_processes();
  }
}catch(Exception ex){
  // one of the processes raised an exception
  clean_all_processes();
}

You can also save the process return values in variables and then check in the failure/exception blocks which process has failed.

You could always use something like mktime to create a known time (midnight, last night) and use difftime to get a double-precision time difference between the two. For a platform-independant solution, unless you go digging into the details of your libraries, you're not going to do much better than that. According to the C spec, the definition of time_t is implementation-defined (meaning that each implementation of the library can define it however they like, as long as library functions with use it behave according to the spec.)

That being said, the size of time_t on my linux machine is 8 bytes, which suggests a long int or a double. So I did:

int main()
{
    for(;;)
    {
        printf ("%ld\n", time(NULL));
        printf ("%f\n", time(NULL));
        sleep(1);
    }
    return 0;
}

The time given by the %ld increased by one each step and the float printed 0.000 each time. If you're hell-bent on using printf to display time_ts, your best bet is to try your own such experiment and see how it work out on your platform and with your compiler.

There are a lot of complicated solutions above. For me? I used GIMP to save a copy of the original PNG file after changing the image size to 32 x 32 pixels.

Just be sure to save it as a *.ico file and use the

Criteria are the only way to specify natural key lookups that take advantage of the special optimization in the second level query cache. HQL does not have any way to specify the necessary hint.

I like np.dot (dot product):

a = numpy.array((xa,ya,za))
b = numpy.array((xb,yb,zb))

distance = (np.dot(a-b,a-b))**.5

You are checking Parent properties for null in your delegate. The same should work with lambda expressions too.

List<AnalysisObject> analysisObjects = analysisObjectRepository
        .FindAll()
        .Where(x => 
            (x.ID == packageId) || 
            (x.Parent != null &&
                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

This will gather all IPs on the host and filter out loopback/link-local and IPv6. This can also be edited to allow for IPv6 only, or both IPv4 and IPv6, as well as allowing loopback/link-local in IP list.

from socket import getaddrinfo, gethostname
import ipaddress

def get_ip(ip_addr_proto="ipv4", ignore_local_ips=True):
    # By default, this method only returns non-local IPv4 Addresses
    # To return IPv6 only, call get_ip('ipv6')
    # To return both IPv4 and IPv6, call get_ip('both')
    # To return local IPs, call get_ip(None, False)
    # Can combime options like so get_ip('both', False)

    af_inet = 2
    if ip_addr_proto == "ipv6":
        af_inet = 30
    elif ip_addr_proto == "both":
        af_inet = 0

    system_ip_list = getaddrinfo(gethostname(), None, af_inet, 1, 0)
    ip_list = []

    for ip in system_ip_list:
        ip = ip[4][0]

        try:
            ipaddress.ip_address(str(ip))
            ip_address_valid = True
        except ValueError:
            ip_address_valid = False
        else:
            if ipaddress.ip_address(ip).is_loopback and ignore_local_ips or ipaddress.ip_address(ip).is_link_local and ignore_local_ips:
                pass
            elif ip_address_valid:
                ip_list.append(ip)

    return ip_list

print(f"Your IP Address is: {get_ip()}")

Returns Your IP Address is: ['192.168.1.118']

If I run get_ip('both', False), it returns

Your IP Address is: ['::1', 'fe80::1', '127.0.0.1', '192.168.1.118', 'fe80::cb9:d2dd:a505:423a']

In droupDown list there are two item add property.

1) Text 2) value

If you want to get text property then u use selecteditem.text

and If you want to select value property then use selectedvalue property

In your case i thing both value and text property are the same so no matter if u use selectedvalue or selecteditem.text

If both are different then they give us different results

Below are the steps that worked for me

1. Mount your google drive in google colab

   from google.colab import drive drive.mount('/content/drive')

2. Insert the directory

   import sys sys.path.insert(0,’/content/drive/My Drive/ColabNotebooks’)

3. check the current directory path

   %cd drive/MyDrive/ColabNotebooks %pwd

4. Import your module or file

   import my_module

5. If you get the following error 'Name Null is not defined' then do the following

   5.1 Download my_module.ipynb from colab as my_module.py file (file->Download .py)

   5.2 Upload the *.py file to drive/MyDrive/ColabNotebooks in Google drive

   5.3 import my_module will work now

Using << aka concat is far more efficient than +=, as the latter creates a temporal object and overrides the first object with the new object.

Why not use globalize? This is only one of the issues that you can run in to when you don't use the english language:

Globalize.parseFloat('0,04'); // 0.04

Some links on stackoverflow to look into:

• Jquery Globalization
• Globalization in JQuery is not working

enumerate() when working on list actually gives the index and the value of the items inside the list. For example:

l = [1, 2, 3, 4, 5, 6, 7, 8, 9]
for i, j in enumerate(list):
    print(i, j)

gives

0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9

where the first column denotes the index of the item and 2nd column denotes the items itself.

In a dictionary

enumm = {0: 1, 1: 2, 2: 3, 4: 4, 5: 5, 6: 6, 7: 7}
for i, j in enumerate(enumm):
    print(i, j)

it gives the output

0 0
1 1
2 2
3 4
4 5
5 6
6 7

where the first column gives the index of the key:value pairs and the second column denotes the keys of the dictionary enumm.

So if you want the first column to be the keys and second columns as values, better try out dict.iteritems()(Python 2) or dict.items() (Python 3)

for i, j in enumm.items():
    print(i, j)

output

0 1
1 2
2 3
4 4
5 5
6 6
7 7

If you need a laymans explanation of the use beyond that provided in the Spring Docs

Consider this code...

class Service {
    @Transactional(propagation=Propagation.REQUIRED)
    public void doSomething() {
        // access a database using a DAO
    }
}

When doSomething() is called it knows it has to start a Transaction on the database before executing. If the caller of this method has already started a Transaction then this method will use that same physical Transaction on the current database connection.

This @Transactional annotation provides a means of telling your code when it executes that it must have a Transaction. It will not run without one, so you can make this assumption in your code that you wont be left with incomplete data in your database, or have to clean something up if an exception occurs.

Transaction management is a fairly complicated subject so hopefully this simplified answer is helpful

const args = ['p0', 'p1', 'p2'];
call_me.apply(this, args);

See MDN docs for Function.prototype.apply().

If the environment supports ECMAScript 6, you can use a spread argument instead:

call_me(...args);

To transform a dataFrame in a real json (not a string) I use:

    from io import StringIO
    import json
    import DataFrame

    buff=StringIO()
    #df is your DataFrame
    df.to_json(path_or_buf=buff,orient='records')
    dfJson=json.loads(buff)

You are mixing mysql and mysqli

Change these lines:

$sql = mysql_query("SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysql_num_rows($sql);

to

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

To get MaxX and MaxY, read on.

For Android device screen coordinates, below concept will work.

Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x; 
int maxY = mdispSize.y;

EDIT:- ** **for devices supporting android api level older than 13. Can use below code.

    Display mdisp = getWindowManager().getDefaultDisplay();
    int maxX= mdisp.getWidth();
    int maxY= mdisp.getHeight();

(x,y) :-

1) (0,0) is top left corner.

2) (maxX,0) is top right corner

3) (0,maxY) is bottom left corner

4) (maxX,maxY) is bottom right corner

here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.

If u want to use display=block it will make the content reader jump, so instead of using display you can set the left attribute to a negative value which does not exist in your html page to be displayed but actually it do.

I hope you must be understanding my point, if I am unable to make u understand u can message me back.

Add the following to add hover effect on disabled button:

.buttonDisabled:hover
  {
    /*your code goes here*/     
  }

There are things that still surprises me... I have a form with dynamic behaviour for two different entities. One entity requires some fields that the other don't. So, my JS code, depending on the entity, does something like: $('#periodo').removeAttr('required'); $("#periodo-container").hide();

and when the user selects the other entity: $("#periodo-container").show(); $('#periodo').prop('required', true);

But sometimes, when the form is submitted, the issue apppears: "An invalid form control with name=periodo'' is not focusable (i am using the same value for the id and name).

To fix this problem, you have to ensurance that the input where you are setting or removing 'required' is always visible.

So, what I did is:

$("#periodo-container").show(); //for making sure it is visible
$('#periodo').removeAttr('required'); 
$("#periodo-container").hide(); //then hide

Thats solved my problem... unbelievable.

Add dependency in package.json and then run npm install

    {
  ...
  ... 
  "dependencies": {
    "express": "*",
    "ejs": "*",
  }
}

Not sure if this is against private APIs/properties but using KVC works for me on ios8

UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Dont care what goes here, since we're about to change below" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Presenting the great... Hulk Hogan!"];
[hogan addAttribute:NSFontAttributeName
              value:[UIFont systemFontOfSize:50.0]
              range:NSMakeRange(24, 11)];
[alertVC setValue:hogan forKey:@"attributedTitle"];



UIAlertAction *button = [UIAlertAction actionWithTitle:@"Label text" 
                                        style:UIAlertActionStyleDefault
                                        handler:^(UIAlertAction *action){
                                                    //add code to make something happen once tapped
}];
UIImage *accessoryImage = [UIImage imageNamed:@"someImage"];
[button setValue:accessoryImage forKey:@"image"];

For the record, it is possible to change alert action's font as well, using those private APIs. Again, it may get you app rejected, I have not yet tried to submit such code.

let alert = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)

let action = UIAlertAction(title: "Some title", style: .Default, handler: nil)
let attributedText = NSMutableAttributedString(string: "Some title")

let range = NSRange(location: 0, length: attributedText.length)
attributedText.addAttribute(NSKernAttributeName, value: 1.5, range: range)
attributedText.addAttribute(NSFontAttributeName, value: UIFont(name: "ProximaNova-Semibold", size: 20.0)!, range: range)

alert.addAction(action)

presentViewController(alert, animated: true, completion: nil)

// this has to be set after presenting the alert, otherwise the internal property __representer is nil
guard let label = action.valueForKey("__representer")?.valueForKey("label") as? UILabel else { return }
label.attributedText = attributedText

For Swift 4.2 in XCode 10 and up the last 2 lines are now:

guard let label = (action!.value(forKey: "__representer")as? NSObject)?.value(forKey: "label") as? UILabel else { return }
        label.attributedText = attributedText

I prefer using a queue over recursion for this kind of simple traversion:

List<File> allFiles = new ArrayList<File>();
Queue<File> dirs = new LinkedList<File>();
dirs.add(new File("/start/dir/"));
while (!dirs.isEmpty()) {
  for (File f : dirs.poll().listFiles()) {
    if (f.isDirectory()) {
      dirs.add(f);
    } else if (f.isFile()) {
      allFiles.add(f);
    }
  }
}

You just need to get selenium package imported, that you can do from command prompt using the command

pip install selenium

When you have to use it in any IDE just import this package, no other documentation required to be imported

For Eg :

import selenium 
print(selenium.__filepath__)

This is just a general command you may use in starting to check the filepath of selenium

I prefer TIMESTAMPDIFF because you can easily change the unit if need be.

I have resolved it by deleting android-support-v4.jar from my Project. Because appcompat_v7 already have a copy of it.

If you have already import appcompat_v7 but still the problem doesn't solve. then try it.

Even though --files is no longer supported, you can use an env variable to provide a list of files:

// karma.conf.js
function getSpecs(specList) {
  if (specList) {
    return specList.split(',')
  } else {
    return ['**/*_spec.js'] // whatever your default glob is
  }
}

module.exports = function(config) {
  config.set({
    //...
    files: ['app.js'].concat(getSpecs(process.env.KARMA_SPECS))
  });
});

Then in CLI:

$ env KARMA_SPECS="spec1.js,spec2.js" karma start karma.conf.js --single-run

If you just want to calculate the schema size without tablespace free space and indexes :

select
   sum(bytes)/1024/1024 as size_in_mega,
   segment_type
from
   dba_segments
where
   owner='<schema's owner>'
group by
   segment_type;

For all schemas

select
   sum(bytes)/1024/1024 as size_in_mega, owner
from
   dba_segments
group by
  owner;

To sum up based on answers here and elsewhere:

1. Check the .NET version of the app pool (e.g. 2.0 vs 4.0)
2. Check that all IIS referenced modules are installed. In this case it was the AJAX extensions (probably not the case these days), but URL Rewrite is a common one.

You could create a new repo with

git init 

and then use

git fetch url-to-repo branchname:refs/remotes/origin/branchname

to fetch just that one branch into a local remote-tracking branch.

1. Find the process ID (PID) for the port (e.g.: 8080)

   On Windows:

   netstat -ao | find "8080"
   

   Other Platforms other than windows :

   lsof -i:8080
   

2. Kill the process ID you found (e.g.: 20712)

   On Windows:

   Taskkill /PID  20712 /F
   

   Other Platforms other than windows :

   kill -9 20712   or kill 20712
   

Since the values are unique, it should be possible to add the values as an additional set of keys. This could be done with the following shortcut.

var foo = {};
foo[foo.apple = "an apple"] = "apple";
foo[foo.pear = "a pear"] = "pear";

This would permit retrieval either via the key or the value:

var key = "apple";
var value = "an apple";

console.log(foo[value]); // "apple"
console.log(foo[key]); // "an apple"

This does assume that there are no common elements between the keys and values.

Altova XmlSpy does this well - you can find an overview here

Try aligning top and bottom of text view to one of the icon, this will make text view sharing same height as them, then set gravity to center_vertical to make the text inside text view center vertically.

<TextView 
        android:id="@+id/func_text" android:layout_toRightOf="@id/icon"
        android:layout_alignTop="@id/icon" android:layout_alignBottom="@id/icon"
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:gravity="center_vertical" />

I know OP asked about the utils::read.csv function, but let me provide an answer for these that come here searching how to do it using readr::read_csv from the tidyverse.

read_csv ("test.csv", col_names=FALSE, col_types = cols (.default = "c", time = "i"))

This should set the default type for all columns as character, while time would be parsed as integer.

on a CENTOS (Red Hat) virtual machine for svn server: edited /etc/init.d/svnserver to change the pid to something that svn can write:

pidfile=${PIDFILE-/home/svn/run/svnserve.pid}

and added option --user=svn:

daemon --pidfile=${pidfile} --user=svn $exec $args

The original pidfile was /var/run/svnserve.pid. The daemon did not start becaseu only root could write there.

 These all work:
/etc/init.d/svnserve start
/etc/init.d/svnserve stop
/etc/init.d/svnserve restart

select field1, field2, 'example' as TempField
from table1

This should work across different SQL implementations.

Edit: Just realized that @Chinmoy was getting at basically the same thing, but I think I may have done a better job ELI5 :)

If you're using a flavor of Spring Data to help persist / fetch things from whatever kind of Repository you've defined, you can probably have your JPA provider do this for you via some clever tricks with method names in your Repository interface class. Allow me to explain.

(As a disclaimer, I just a few moments ago did/still am figuring this out for myself.)

For example, if I am storing Tokens in my database, I might have an entity class that looks like this:

@Data // << Project Lombok convenience annotation
@Entity
public class Token {
    @Id
    @Column(name = "TOKEN_ID")
    private String tokenId;

    @Column(name = "TOKEN")
    private String token;

    @Column(name = "EXPIRATION")
    private String expiration;

    @Column(name = "SCOPE")
    private String scope;
}

And I probably have a CrudRepository<K,V> interface defined like this, to give me simple CRUD operations on that Repository for free.

@Repository
// CrudRepository<{Entity Type}, {Entity Primary Key Type}>
public interface TokenRepository extends CrudRepository<Token, String> { }

And when I'm looking up one of these tokens, my purpose might be checking the expiration or scope, for example. In either of those cases, I probably don't have the tokenId handy, but rather just the value of a token field itself that I want to look up.

To do that, you can add an additional method to your TokenRepository interface in a clever way to tell your JPA provider that the value you're passing in to the method is not the tokenId, but the value of another field within the Entity class, and it should take that into account when it is generating the actual SQL that it will run against your database.

@Repository
// CrudRepository<{Entity Type}, {Entity Primary Key Type}>
public interface TokenRepository extends CrudRepository<Token, String> { 
    List<Token> findByToken(String token);
}

I read about this on the Spring Data R2DBC docs page, and it seems to be working so far within a SpringBoot 2.x app storing in an embedded H2 database.

I think I was trying something very similar to the original poster. the get() worked for me, although the name inside the chart was not inherited. Here is the code that worked for me.

#install it if you dont have it
library(quantmod)

# a list of stock tickers
myStocks <- c("INTC", "AAPL", "GOOG", "LTD")

# get some stock prices from default service
getSymbols(myStocks)

# to pause in between plots
par(ask=TRUE)

# plot all symbols
for (i in 1:length(myStocks)) {
    chartSeries(get(myStocks[i]), subset="last 26 weeks")
}

If you're running test Suite via @RunWith(Suite.class) @Suite.SuiteClasses({}) check if all provided classes are really test classes ;).

In my case one of the classes was an actual implementation, not a test class. Just a silly typo.

Declaration says "this thing exists somewhere":

int foo();       // function
extern int bar;  // variable
struct T
{
   static int baz;  // static member variable
};

Definition says "this thing exists here; make memory for it":

int foo() {}     // function
int bar;         // variable
int T::baz;      // static member variable

Initialisation is optional at the point of definition for objects, and says "here is the initial value for this thing":

int bar = 0;     // variable
int T::baz = 42; // static member variable

Sometimes it's possible at the point of declaration instead:

struct T
{
   static int baz = 42;
};

…but that's getting into more complex features.

=> just what jay said just delete those registry entries which are pointing to other paths other than on c:\windows\system32.Those are the culprits of the error.I got those errors on my vb6 IDE and after deleting those anomalous registry entries the problem was fixed. works like a charm.

To ignore all untracked files in any submodule use the following command to ignore those changes.

git config --global diff.ignoreSubmodules dirty

It will add the following configuration option to your local git config:

[diff]
  ignoreSubmodules = dirty

Cast the variable to a float before doing the comparison:

if float(i) < float(x):

The problem is that you are comparing strings to floats, which will not work.

Your code is reading a sequence of UTF8-encoded bytes, and decoding them using an 8-bit encoding.

You need to fix that code to decode the bytes as UTF8.

Alternatively (not ideal), you could convert the bad string back to the original byte array—by encoding it using the incorrect encoding—then re-decode the bytes as UTF8.

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

I am facing the same problem with you. Based on the hint of @thuliha, the following codes has solved my issues.

In the html file, modify as the following sample:

<img class="img-responsive center-block" src=".....png" alt="Third slide">

In the carousel.css, modify the class:

.carousel .item {
  text-align: center;
  height: 470px;
  background-color: #777;
}

There's another good way, just edit the file apache2.conf theres a line at the end

IncludeOptional sites-enabled/*.conf

just remove the .conf at the end, like this

IncludeOptional sites-enabled/*

and restart the server.

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

When loading the Properties from a Class in the package com.al.common.email.templates you can use

Properties prop = new Properties();
InputStream in = getClass().getResourceAsStream("foo.properties");
prop.load(in);
in.close();

(Add all the necessary exception handling).

If your class is not in that package, you need to aquire the InputStream slightly differently:

InputStream in = 
 getClass().getResourceAsStream("/com/al/common/email/templates/foo.properties");

Relative paths (those without a leading '/') in getResource()/getResourceAsStream() mean that the resource will be searched relative to the directory which represents the package the class is in.

Using java.lang.String.class.getResource("foo.txt") would search for the (inexistent) file /java/lang/String/foo.txt on the classpath.

Using an absolute path (one that starts with '/') means that the current package is ignored.

Your url String needs variable markers for the map you pass to work, like:

String url = "https://app.example.com/hr/email?{email}";

Or you could explicitly code the query params into the String to begin with and not have to pass the map at all, like:

String url = "https://app.example.com/hr/[email protected]";

Use Default toolkit for this

frame.setIconImage(Toolkit.getDefaultToolkit().getImage("Icon.png"));

While saving the response of get request, same error was thrown on Python 3.7 on window 10. The response received from the URL, encoding was UTF-8 so it is always recommended to check the encoding so same can be passed to avoid such trivial issue as it really kills lots of time in production

import requests
resp = requests.get('https://en.wikipedia.org/wiki/NIFTY_50')
print(resp.encoding)
with open ('NiftyList.txt', 'w') as f:
    f.write(resp.text)

When I added encoding="utf-8" with the open command it saved the file with the correct response

with open ('NiftyList.txt', 'w', encoding="utf-8") as f:
    f.write(resp.text)

while (<@INC>)

This joins the paths in @INC together in a string, separated by spaces, then calls glob() on the string, which then iterates through the space-separated components (unless there are file-globbing meta-characters.)

This doesn't work so well if there are paths in @INC containing spaces, \, [], {}, *, ?, or ~, and there seems to be no reason to avoid the safe alternative:

for (@INC)

$id = 101;

$sql = 'SELECT * FROM ur_tbl t WHERE t.email_id = '. $id;
$email = Yii::app()->db->createCommand($sql)->queryAll();

var_dump($email);

Pelo Hyper-V:

private PerformanceCounter theMemCounter = new PerformanceCounter(
    "Hyper-v Dynamic Memory VM",
    "Physical Memory",
    Process.GetCurrentProcess().ProcessName); 

What worked for me was to add the file under My Project/Java Resources/src and then use

this.getClass().getClassLoader().getResourceAsStream("myfile.txt");

I didn't need to explicitly add this file to the path (adding it to /src does that apparently)

Note also that when you used arrays in C++ you might have had somewhat different needs, which are solved in different ways in Python:

1. You might have needed just a collection of items; Python lists deal with this usecase just perfectly.
2. You might have needed a proper array of homogenous items. Python lists are not a good way to store arrays.

Python solves the need in arrays by NumPy, which, among other neat things, has a way to create an array of known size:

from numpy import *

l = zeros(10)

Code posted by you is correct and should have worked. But check exactly what you have in the char*. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL. Check what you have in the char* against maximum values that float and double can represent on your computer.

Check this page for strtod reference and this page for atof reference.

I have tried the example you provided in both Windows and Linux and it worked fine.

I'm having a problem with your script in Firefox. When I scroll down, the script continues to add a margin to the page and I never reach the bottom of the page. This occurs because the ActionBox is still part of the page elements. I posted a demo here.

• One solution would be to add a position: fixed to the CSS definition, but I see this won't work for you
• Another solution would be to position the ActionBox absolutely (to the document body) and adjust the top.
• Updated the code to fit with the solution found for others to benefit.

UPDATED:

CSS

#ActionBox {
 position: relative;
 float: right;
}

Script

var alert_top = 0;
var alert_margin_top = 0;

$(function() {
  alert_top = $("#ActionBox").offset().top;
  alert_margin_top = parseInt($("#ActionBox").css("margin-top"),10);

  $(window).scroll(function () {
    var scroll_top = $(window).scrollTop();
    if (scroll_top > alert_top) {
      $("#ActionBox").css("margin-top", ((scroll_top-alert_top)+(alert_margin_top*2)) + "px");
      console.log("Setting margin-top to " + $("#ActionBox").css("margin-top"));
    } else {
      $("#ActionBox").css("margin-top", alert_margin_top+"px");
    };
  });
});

Also it is important to add a base (10 in this case) to your parseInt(), e.g.

parseInt($("#ActionBox").css("top"),10);

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

If start can't find what it's looking for, it does what you describe.

Since what you're doing should work, it's very likely you're leaving out some quotes (or putting extras in).

am assuming that you want to know how to format numbers in SSRS

Just right click the TextBox on which you want to apply formatting, go to its expression.

suppose its expression is something like below

=Fields!myField.Value

then do this

=Format(Fields!myField.Value,"##.##") 

or

=Format(Fields!myFields.Value,"00.00")

difference between the two is that former one would make 4 as 4 and later one would make 4 as 04.00

this should give you an idea.

also: you might have to convert your field into a numerical one. i.e.

  =Format(CDbl(Fields!myFields.Value),"00.00")

so: 0 in format expression means, when no number is present, place a 0 there and # means when no number is present, leave it. Both of them works same when numbers are present ie. 45.6567 would be 45.65 for both of them:

UPDATE :

if you want to apply variable formatting on the same column based on row values i.e. you want myField to have no formatting when it has no decimal value but formatting with double precision when it has decimal then you can do it through logic. (though you should not be doing so)

Go to the appropriate textbox and go to its expression and do this:

=IIF((Fields!myField.Value - CInt(Fields!myField.Value)) > 0, 
    Format(Fields!myField.Value, "##.##"),Fields!myField.Value)

so basically you are using IIF(condition, true,false) operator of SSRS, ur condition is to check whether the number has decimal value, if it has, you apply the formatting and if no, you let it as it is.

this should give you an idea, how to handle variable formatting.

It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.

If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate and colMeans, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.

However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for loop.

> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > 

So in your case, if you just wanted to print the mean of your Tandem object 5 times:

for (ii in 1:5) {     Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL)     TandemMean <- mean(Tandem)     print(TandemMean) } 

As mentioned above, replicate is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.

set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) {     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) }  tandem[1] tandem[100] tandem[20:25] 

...creates this output:

> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { +     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } >  > tandem[1] [[1]] [1] 1.511923  > tandem[100] [[1]] [1] 1.496777  > tandem[20:25] [[1]] [1] 1.500669  [[2]] [1] 1.487552  [[3]] [1] 1.503409  [[4]] [1] 1.501362  [[5]] [1] 1.499728  [[6]] [1] 1.492798  >  

Why do you need to state both 'x' and 'y' before the ':'?

Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to

def f(x, y) : return x + y

just without binding it to a name like f.

Also how do you make it return multiple arguments?

The same way like with a function. Preferably, you return a tuple:

lambda x, y: (x+y, x-y)

Or a list, or a class, or whatever.

The thing with self.entry_1.bind should be answered by Demosthenex.

The simplest and most elegant way of understanding the two in my opinion is this. Concurrency allows interleaving of execution and so can give the illusion of parallelism. This means that a concurrent system can run your Youtube video alongside you writing up a document in Word, for example. The underlying OS, being a concurrent system, enables those tasks to interleave their execution. Because computers execute instructions so quickly, this gives the appearance of doing two things at once.

Parallelism is when such things really are in parallel. In the example above, you might find the video processing code is being executed on a single core, and the Word application is running on another. Note that this means that a concurrent program can also be in parallel! Structuring your application with threads and processes enables your program to exploit the underlying hardware and potentially be done in parallel.

Why not have everything be parallel then? One reason is because concurrency is a way of structuring programs and is a design decision to facilitate separation of concerns, whereas parallelism is often used in the name of performance. Another is that some things fundamentally cannot fully be done in parallel. An example of this would be adding two things to the back of a queue - you cannot insert both at the same time. Something must go first and the other behind it, or else you mess up the queue. Although we can interleave such execution (and so we get a concurrent queue), you cannot have it parallel.

Hope this helps!

Binds a handler to an event (like click) for all current - and future - matched element. Can also bind custom events.

link text

$(function(){
    $(".myclass").live("click", function() {
        // do something
    });
});

Solution is very simple. Find *.module.ts files and comment declarations. In your case find addevent.module.ts file and remove/comment one line below:

@NgModule({
  declarations: [
    // AddEvent, <-- Comment or Remove This Line
  ],
  imports: [
    IonicPageModule.forChild(AddEvent),
  ],
})

This solution worked in ionic 3 for pages that generated by ionic-cli and works in both ionic serve and ionic cordova build android --prod --release commands!

There's a 3 ways to access the scope inside of the 'setTimeout' function

First,

const self = this
setTimeout(function() {
  self.setState({position:1})
}, 3000)

Second is to use ES6 arrow function, cause arrow function didn't have itself scope(this)

setTimeout(()=> {
   this.setState({position:1})
}, 3000)

Third one is to bind the scope inside of the function

setTimeout(function(){
   this.setState({position:1})
}.bind(this), 3000)

@Cybernate, I was looking for the same script today thanks for your input. However I changed it just a bit for jQuery...

function clock(){
    $('body').prepend('<div id="clock"><label id="minutes">00</label>:<label id="seconds">00</label></div>');
         var totalSeconds = 0;
        setInterval(setTime, 1000);
        function setTime()
        {
            ++totalSeconds;
            $('#clock > #seconds').html(pad(totalSeconds%60));
            $('#clock > #minutes').html(pad(parseInt(totalSeconds/60)));
        }
        function pad(val)
        {
            var valString = val + "";
            if(valString.length < 2)
            {
                return "0" + valString;
            }
            else
            {
                return valString;
            }
        }
}
$(document).ready(function(){
    clock();
    });

the css part:

<style>
#clock {
    padding: 10px;
    position:absolute;
    top: 0px;
    right: 0px;
    color: black;
}
</style>

The problem is that flex: 1 sets flex-basis: 0. Instead, you need

  flex-grow: 1;
}

In this example, how do I specify the value of "constrArg" in MyBeanService with the @Autowire annotation? Is there any way to do this?

No, not in the way that you mean. The bean representing MyConstructorClass must be configurable without requiring any of its client beans, so MyBeanService doesn't get a say in how MyConstructorClass is configured.

This isn't an autowiring problem, the problem here is how does Spring instantiate MyConstructorClass, given that MyConstructorClass is a @Component (and you're using component-scanning, and therefore not specifying a MyConstructorClass explicitly in your config).

As @Sean said, one answer here is to use @Value on the constructor parameter, so that Spring will fetch the constructor value from a system property or properties file. The alternative is for MyBeanService to directly instantiate MyConstructorClass, but if you do that, then MyConstructorClass is no longer a Spring bean.

If you're trying to npm install on a folder that's being rsync'd from somewhere else, remember to add this to your rsync --exclude

Otherwise, NPM will try to add node_modules and rsync will remove it immediately, causing many npm WARN enoent ENOENT: no such file or directory, open errors.

Read HTML File and Use Ruby's CSV and nokogiri to Output to .csv.

Based on @audiodude's answer but modified in the following ways:

• Reads from a file to get the HTML. This is handy for long HTML tables, but easily modified to just use a static String if your HTML table is small.
• Uses CSV's built-in library for converting an Array into a CSV row.
• Outputs to a .csv file instead of just printing to STDOUT.
• Gets both the table headers (th) and the table body (td).

# Convert HTML table to CSV format.

require "nokogiri"

html_file_path = ""

html_string = File.read( html_file_path )

doc = Nokogiri::HTML( html_string )

CSV.open( Rails.root.join( Time.zone.now.to_s( :file ) + ".csv" ), "wb" ) do |csv|
  doc.xpath( "//table//tr" ).each do |row|
    csv << row.xpath( "th|td" ).collect( &:text ).collect( &:strip )
  end
end

I hope my encoding here is right ;D To make it faster just use the ugly getInstance() call of GregorianCalendar instead of constructor call:

import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class DateTest {

   public static void main(final String[] args) throws Exception {
      // do not forget the type cast :/
      GregorianCalendar gcal = (GregorianCalendar) GregorianCalendar.getInstance();
      XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gcal);
      System.out.println(xgcal);
   }

}

Suppose your hex string is something like

>>> hex_string = "deadbeef"

Convert it to a string (Python = 2.7):

>>> hex_data = hex_string.decode("hex")
>>> hex_data
"\xde\xad\xbe\xef"

or since Python 2.7 and Python 3.0:

>>> bytes.fromhex(hex_string)  # Python = 3
b'\xde\xad\xbe\xef'

>>> bytearray.fromhex(hex_string)
bytearray(b'\xde\xad\xbe\xef')

Note that bytes is an immutable version of bytearray.

If the list is in random order, you can just take the first 50.

Otherwise, use

import random
random.sample(the_list, 50)

random.sample help text:

sample(self, population, k) method of random.Random instance
    Chooses k unique random elements from a population sequence.

    Returns a new list containing elements from the population while
    leaving the original population unchanged.  The resulting list is
    in selection order so that all sub-slices will also be valid random
    samples.  This allows raffle winners (the sample) to be partitioned
    into grand prize and second place winners (the subslices).

    Members of the population need not be hashable or unique.  If the
    population contains repeats, then each occurrence is a possible
    selection in the sample.

    To choose a sample in a range of integers, use xrange as an argument.
    This is especially fast and space efficient for sampling from a
    large population:   sample(xrange(10000000), 60)

In a general sense, SQL Server does not support regular expressions and you cannot use them in the native T-SQL code.

You could write a CLR function to do that. See here, for example.

I think you should append .value in IF statement:

If Cells(i, "A").Value <> "Miami" And Cells(i, "D").Value <> "Florida" Then
    Cells(i, "C").Value = "BA"
End IF

People need to put down the gun, step away from the ledge, and think for a minute. It turns out there are objective, concrete, and undeniable advantages to DVCS that will make a HUGE difference in a team's productivity.

It all comes down to Branching and Merging.

Before DVCS, the guiding principle was "Pray to God that you don't have to get into branching and merging. And if you do, at least beg Him to let it be very, very simple."

Now, with DVCS, branching (and merging) is so much improved, the guiding principle is, "Do it at the drop of a hat. It will give you a ton of benefits and not cause you any problems."

And that is a HUGE productivity booster for any team.

The problem is, for people to understand what I just said and be convinced that it is true, they have to first invest in a little bit of a learning curve. They don't have to learn Git or any other DVCS itself ... they just need to learn how Git does branching and merging. Read and re-read some articles and blog posts, taking it slow, and working through it until you see it. That might take the better part of 2 or 3 full days.

But once you see that, you won't even consider choosing a non-DVCS. Because there really are clear, objective, concrete advantages to DVCS, and the biggest wins are in the area of branching and merging.

In my case the php module was not loaded. Try this:

1. Check which modules are loaded: apache2ctl -M. Look for module like php7_module (shared)
2. If no php module is listed, then try to load the module that corresponds to your php version. In my case the php packet is libapache2-mod-php7.3. So I did: a2enmod php7.3 and the problem was solved.

First, Identify the user you are logged in as:

 select user();
 select current_user();

The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as root@localhost in mysql.

Grant_priv to root@localhost. Here is how you can check.

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host      | user             | password                                  | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root             | ***************************************** | N          | Y          |
| localhost | debian-sys-maint | ***************************************** | Y          | Y          |
| localhost | staging          | ***************************************** | N          | N          |
+-----------+------------------+-------------------------------------------+------------+------------+

You can see that the Grant_priv is set to N for root@localhost. This needs to be Y. Below is how to fixed this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

I logged back in, it was fine.

I'm going to guess you aren't getting errors or you would've mentioned them. If that's the case, try removing the href attribute value so the page doesn't navigate away before your code is executed. In Angular it's perfectly acceptable to leave href attributes blank.

<a href="" data-router="article" ng-click="changeListName('metro')">

Also I don't know what data-router is doing but if you still aren't getting the proper result, that could be why.

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

After looking in the windows event log I saw an error coming from the System.ServiceModel.Activation.TcpWorkerProcess class.

Are you hosting your wcf service in IIS with netTcpBinding and port sharing?

It seems there is a bug in IIS port sharing feature, check the fix:

My solution is to host your WCF service in a Windows Service.

Look at the picture, it's a result set of a query select * from employee

and the next() method of ResultSet class help to move the cursor to the next row of a returned result set which is rs in your example.

:)

I got the same error in this case:

var result = Db.SystemLog
.Where(log =>
    eventTypeValues.Contains(log.EventType)
    && (
        search.Contains(log.Id.ToString())
        || log.Message.Contains(search)
        || log.PayLoad.Contains(search)
        || log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
    )
)
.OrderByDescending(log => log.Id)
.Select(r => r);

After spending way too much time debugging, I figured out that error appeared in the logic expression.

The first line search.Contains(log.Id.ToString()) does work fine, but the last line that deals with a DateTime object made it fail miserably:

|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)

Remove the problematic line and problem solved.

I do not fully understand why, but it seems as ToString() is a LINQ expression for strings, but not for Entities. LINQ for Entities deals with database queries like SQL, and SQL has no notion of ToString(). As such, we can not throw ToString() into a .Where() clause.

But how then does the first line work? Instead of ToString(), SQL have CAST and CONVERT, so my best guess so far is that linq for entities uses that in some simple cases. DateTime objects are not always found to be so simple...

100vh works for me, but at first I had used javascript (actually jQuery, but you can adapt it), to tackle a similar problw.

HTML

<body>
  <div id="wrapper">
    <div id="header">header</div>
    <div id="content">content</div>
  </div>
</body>

js/jQuery

var innerWindowHeight = $(window).height();
var headerHeight = $("#header").height();
var contentHeight = innerWindowHeight - headerHeight;
$(".content").height(contentHeight + "px");

Alternately, you can just use 111px if you don't want to calculate headerHeight.

Also, you may want to put this in a window resize event, to rerun the script if the window height increases for example.

For the sake of bandwidth saving, we shouldn't include <div> for each of <label> and <input> pair

This solution may serve you better and may increase readability

<div class="form">
            <label for="product_name">Name</label>
            <input id="product_name" name="product[name]" size="30" type="text" value="4">
            <label for="product_stock">Stock</label>
            <input id="product_stock" name="product[stock]" size="30" type="text" value="-1">
            <label for="price_amount">Amount</label>
            <input id="price_amount" name="price[amount]" size="30" type="text" value="6.0">
</div>

The css for above form would be

.form > label
{
  float: left;
  clear: right;
}

.form > input
{
  float: right;
}

I believe the output would be as following:

can gridmove be of any assistance?

very handy tool on larger screens...

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

You can also override settings, particularly useful in tests:

from django.test import override_settings

with override_settings(USE_TZ=False):
    # Insert your code that causes the warning here
    pass

This will prevent you from seeing the warning, at the same time anything in your code that requires a timezone aware datetime may give you problems. If this is the case, see kravietz answer.

To access field or method of an object use dot .:

user = User()
print user.fullName

If a name of the field will be defined at run time, use buildin getattr function:

field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName

You can use DropDownButton class in order to create drop down list :

...
...
String dropdownValue = 'One';
...
...
Widget build(BuildContext context) {
return Scaffold(
  body: Center(
    child: DropdownButton<String>(
      value: dropdownValue,
      onChanged: (String newValue) {
        setState(() {
          dropdownValue = newValue;
        });
      },
      items: <String>['One', 'Two', 'Free', 'Four']
          .map<DropdownMenuItem<String>>((String value) {
        return DropdownMenuItem<String>(
          value: value,
          child: Text(value),
        );
      }).toList(),
    ),
  ),
);
...
...

please refer to this flutter web page

ActiveCell.Offset(0, -1).Select

You need to enclose that in <%! %> as follows:

<%!

public String getQuarter(int i){
String quarter;
switch(i){
        case 1: quarter = "Winter";
        break;

        case 2: quarter = "Spring";
        break;

        case 3: quarter = "Summer I";
        break;

        case 4: quarter = "Summer II";
        break;

        case 5: quarter = "Fall";
        break;

        default: quarter = "ERROR";
}

return quarter;
}

%>

You can then invoke the function within scriptlets or expressions:

<%
     out.print(getQuarter(4));
%>

or

<%= getQuarter(17) %>

In C/C++ a string is an array of char terminated with a NULL byte ('\0');

1. Your string str has not been initialized.
2. You must concatenate strings and you are trying to concatenate a single char (without the null byte so it's not a string) to a string.

The code should look like this:

char str[1024] = "Hello World"; //this will add all characters and a NULL byte to the array
char tmp[2] = "."; //this is a string with the dot 
strcat(str, tmp);  //here you concatenate the two strings

Note that you can assign a string literal to an array only during its declaration.
For example the following code is not permitted:

char str[1024];
str = "Hello World"; //FORBIDDEN

and should be replaced with

char str[1024];
strcpy(str, "Hello World"); //here you copy "Hello World" inside the src array 

just and another class to jumbotron

It will work perfectly

This is nowhere definied in the JDBC API contract, but if you're lucky, the JDBC driver in question may return the complete SQL by just calling PreparedStatement#toString(). I.e.

System.out.println(preparedStatement);

To my experience, the ones which do so are at least the PostgreSQL 8.x and MySQL 5.x JDBC drivers. For the case your JDBC driver doesn't support it, your best bet is using a statement wrapper which logs all setXxx() methods and finally populates a SQL string on toString() based on the logged information. For example Log4jdbc or P6Spy.

From the bash man page:

Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard.

So you can do this:

echo $'hello\tworld'

If you have a custom template and view you may exclude the field and use {{ modelform.instance.field }} to get the value.

also you may prefer to use in the view:

form.fields['field_name'].widget = forms.HiddenInput()

but I'm not sure it will protect save method on post.

Hope it helps.

You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close() method:

>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor

The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.

Since the implementation of os.system() does not create any Python file objects, it does not seem likely that the system() call is the origin of the error. Maybe you could show a bit more code?

Based on ArsenMkrt's reply, but this one allows you to capture a control in your form (I'm writing a tool for example that has a WebBrowser control in it and want to capture just its display). Note the use of PointToScreen method:

Having the Bitmap object you can just call Save on it

private void btnCapture_Click(object sender, EventArgs e)
{
  webBrowser.GetScreenshot().Save("C://test.jpg", ImageFormat.Jpeg);
}

The above assumes the GC will grab the bitmap, but maybe it's better to assign the result of someControl.getScreenshot() to a Bitmap variable, then dispose that variable manually when finished with each image, especially if you're doing this grabbing often (say you have a list of webpages you want to load and save screenshots of them):

private void btnCapture_Click(object sender, EventArgs e)
{
  Bitmap bitmap = webBrowser.GetScreenshot();
  bitmap.ShowSaveFileDialog();
  bitmap.Dispose(); //release bitmap resources
}

Even better, could employ a using clause, which has the added benefit of releasing the bitmap resources even in case of an exception occuring inside the using (child) block:

private void btnCapture_Click(object sender, EventArgs e)
{
  using(Bitmap bitmap = webBrowser.GetScreenshot())
    bitmap.ShowSaveFileDialog();
  //exit from using block will release bitmap resources even if exception occured
}

Update:

Now WebCapture tool is ClickOnce-deployed (http://gallery.clipflair.net/WebCapture) from the web (also has nice autoupdate support thanks to ClickOnce) and you can find its source code at https://github.com/Zoomicon/ClipFlair/tree/master/Server/Tools/WebCapture

PixlUI project allows you to use textAllCaps in any textview or subclass of textview including: Button, EditText AutoCompleteEditText Checkbox RadioButton and several others.

You will need to create your textviews using the pixlui version rather than the ones from the android source, meaning you have to do this:

<com.neopixl.pixlui.components.textview.TextView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world"
        pixlui:textAllCaps="true" />

PixlUI also allows you to set a custom typeface/font which you put in your assets folder.

I'm working on a Gradle fork of the PixlUI framework which uses gradle and allows one to specify textAllCaps as well as the typeface from styles rather than requiring them inline as the original project does.

Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.

Linux Crontab Format

MIN HOUR DOM MON DOW CMD

Example::Scheduling a Job For a Specific Time

The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.

Please note that the time field uses 24 hours format. So, for 8 AM use 8, and for 8 PM use 20.

30 08 10 06 * /home/yourname/full-backup

• 30 – 30th Minute
• 08 – 08 AM
• 10 – 10th Day
• 06 – 6th Month (June)
• *– Every day of the week

In your case, for 2.30PM,

30 14 * * * YOURCMD

1. 30 – 30th Minute
2. 14 – 2PM
3. *– Every day
4. *– Every month
5. *– Every day of the week

Simply call window.frameElement from your framed page. If the page is not in a frame then frameElement will be null.

The other way (getting the window element inside a frame is less trivial) but for sake of completeness:

/**
 * @param f, iframe or frame element
 * @return Window object inside the given frame
 * @effect will append f to document.body if f not yet part of the DOM
 * @see Window.frameElement
 * @usage myFrame.document = getFramedWindow(myFrame).document;
 */
function getFramedWindow(f)
{
    if(f.parentNode == null)
        f = document.body.appendChild(f);
    var w = (f.contentWindow || f.contentDocument);
    if(w && w.nodeType && w.nodeType==9)
        w = (w.defaultView || w.parentWindow);
    return w;
}

Set This in OkHttpClient.Builder() Object

val httpClient = OkHttpClient.Builder()
        httpClient.connectTimeout(5, TimeUnit.MINUTES) // connect timeout

Try changing the name of the Activity in your AndroidManifest.xml file.

Right now it says:

<activity android:name="LandingActivity" >

Try either adding a period to the beginning of the Activity's name:

<activity android:name=".LandingActivity" >

Or adding the package name to the beginning of the Activity's name:

<activity android:name="com.trackingeng.LandingActivity" >

It also may be a problem that your package name has only two components separated by periods (your package name is "com.trackingeng"; a more standard package name would be "com.trackingeng.app")

The standard streams have a boolalpha flag that determines what gets displayed -- when it's false, they'll display as 0 and 1. When it's true, they'll display as false and true.

There's also an std::boolalpha manipulator to set the flag, so this:

#include <iostream>
#include <iomanip>

int main() {
    std::cout<<false<<"\n";
    std::cout << std::boolalpha;   
    std::cout<<false<<"\n";
    return 0;
}

...produces output like:

0
false

For what it's worth, the actual word produced when boolalpha is set to true is localized--that is, <locale> has a num_put category that handles numeric conversions, so if you imbue a stream with the right locale, it can/will print out true and false as they're represented in that locale. For example,

#include <iostream>
#include <iomanip>
#include <locale>

int main() {
    std::cout.imbue(std::locale("fr"));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

...and at least in theory (assuming your compiler/standard library accept "fr" as an identifier for "French") it might print out faux instead of false. I should add, however, that real support for this is uneven at best--even the Dinkumware/Microsoft library (usually quite good in this respect) prints false for every language I've checked.

The names that get used are defined in a numpunct facet though, so if you really want them to print out correctly for particular language, you can create a numpunct facet to do that. For example, one that (I believe) is at least reasonably accurate for French would look like this:

#include <array>
#include <string>
#include <locale>
#include <ios>
#include <iostream>

class my_fr : public std::numpunct< char > {
protected:
    char do_decimal_point() const { return ','; }
    char do_thousands_sep() const { return '.'; }
    std::string do_grouping() const { return "\3"; }
    std::string do_truename() const { return "vrai";  }
    std::string do_falsename() const { return "faux"; }
};

int main() {
    std::cout.imbue(std::locale(std::locale(), new my_fr));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

And the result is (as you'd probably expect):

0
faux

You cannot really change the whole URL in the location bar without redirecting (think of the security issues!).

However you can change the hash part (whats after the #) and read that: location.hash

ps. prevent the default onclick redirect of a link by something like:

$("#link").bind("click",function(e){
  doRedirectFunction();
  e.preventDefault();
})

You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.

This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:
tutsme-webdesign.info/bootstrap-3-toggable-tabs-and-pills

Note that you can also set the title directly with javascript, i.e.,

$window.document.title = someTitleYouCreated;

This does not have data binding, but it suffices when putting ng-app in the <html> tag is problematic. (For example, using JSP templates where <head> is defined in exactly one place, yet you have more than one app.)

Look at this code, it can help you to get out of the loop fast!

foreach (var name in parent.names)
{
   if (name.lastname == null)
   {
      Violated = true;
      this.message = "lastname reqd";
      break;
   }
   else if (name.firstname == null)
   {
      Violated = true;
      this.message = "firstname reqd";
      break;
   }
}

(You should you as Else-If statement to check the for the three different state (positive, negative, 0)

Here is a simple example (excludes the possibility of non-integer values)

  import java.util.Scanner;

  public class Compare {

   public static void main(String[] args) { 

    Scanner input = new Scanner(System.in);

    System.out.print("Enter a number: ");
    int number = input.nextInt();

    if( number == 0)
    { System.out.println("Number is equal to zero"); }
    else if (number > 0)
    { System.out.println("Number is positive"); }
    else 
    { System.out.println("Number is negative"); }


  }
 }

To alter the password expiry policy for a certain user profile in Oracle first check which profile the user is using:

select profile from DBA_USERS where username = '<username>';

Then you can change the limit to never expire using:

alter profile <profile_name> limit password_life_time UNLIMITED;

If you want to previously check the limit you may use:

select resource_name,limit from dba_profiles where profile='<profile_name>';

The make uses the $ for its own variable expansions. E.g. single character variable $A or variable with a long name - ${VAR} and $(VAR).

To put the $ into a command, use the $$, for example:

all:
  @echo "Please execute next commands:"
  @echo 'setenv PATH /usr/local/greenhills/mips5/linux86:$$PATH'

Also note that to make the "" and '' (double and single quoting) do not play any role and they are passed verbatim to the shell. (Remove the @ sign to see what make sends to shell.) To prevent the shell from expanding $PATH, second line uses the ''.

The most straight forward, and most efficient, would be to simply loop through the characters in the string:

int cnt = 0;
foreach (char c in test) {
  if (c == '&') cnt++;
}

You can use Linq extensions to make a simpler, and almost as efficient version. There is a bit more overhead, but it's still surprisingly close to the loop in performance:

int cnt = test.Count(c => c == '&');

Then there is the old Replace trick, however that is better suited for languages where looping is awkward (SQL) or slow (VBScript):

int cnt = test.Length - test.Replace("&", "").Length;

Note: see the warning in the comments about how this can affect Electron applications.

As of v8.0 shipped August 2017, the NODE_OPTIONS environment variable exposes this configuration (see NODE_OPTIONS has landed in 8.x!). Per the article, only options whitelisted in the source (note: not an up-to-date-link!) are permitted, which includes "--max_old_space_size". Note that this article's title seems a bit misleading - it seems NODE_OPTIONS had already existed, but I'm not sure it exposed this option.

So I put in my .bashrc:
export NODE_OPTIONS=--max_old_space_size=4096

I use the old PHP way..It unsets all session variables and doesn't require to specify each one of them in an array. And after unsetting the variables we destroy the session.

session_unset();
session_destroy();

You can get all the IP addresses with GetHostAddresses like this:

$ips = [System.Net.Dns]::GetHostAddresses("yourhosthere")

You can iterate over them like so:

[System.Net.Dns]::GetHostAddresses("yourhosthere") | foreach {echo $_.IPAddressToString }

A server may have more than one IP, so this will return an array of IPs.

Here's some more detailed information on what Client, Resource, and Session are all about.

Client:

• low-level AWS service access
• generated from AWS service description
• exposes botocore client to the developer
• typically maps 1:1 with the AWS service API
• all AWS service operations are supported by clients
• snake-cased method names (e.g. ListBuckets API => list_buckets method)

Here's an example of client-level access to an S3 bucket's objects (at most 1000**):

import boto3

client = boto3.client('s3')
response = client.list_objects_v2(Bucket='mybucket')
for content in response['Contents']:
    obj_dict = client.get_object(Bucket='mybucket', Key=content['Key'])
    print(content['Key'], obj_dict['LastModified'])

** you would have to use a paginator, or implement your own loop, calling list_objects() repeatedly with a continuation marker if there were more than 1000.

Resource:

• higher-level, object-oriented API
• generated from resource description
• uses identifiers and attributes
• has actions (operations on resources)
• exposes subresources and collections of AWS resources
• does not provide 100% API coverage of AWS services

Here's the equivalent example using resource-level access to an S3 bucket's objects (all):

import boto3

s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
for obj in bucket.objects.all():
    print(obj.key, obj.last_modified)

Note that in this case you do not have to make a second API call to get the objects; they're available to you as a collection on the bucket. These collections of subresources are lazily-loaded.

You can see that the Resource version of the code is much simpler, more compact, and has more capability (it does pagination for you). The Client version of the code would actually be more complicated than shown above if you wanted to include pagination.

Session:

• stores configuration information (primarily credentials and selected region)
• allows you to create service clients and resources
• boto3 creates a default session for you when needed

A useful resource to learn more about these boto3 concepts is the introductory re:Invent video.

You can try progress bar instead of seek bar

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_marginBottom="35dp"
    />

There is one common answer I haven't see here yet, which is the Window Function. It is an alternative to the correlated sub-query, if your DB supports it.

SELECT sensorID,timestamp,sensorField1,sensorField2 
FROM (
    SELECT sensorID,timestamp,sensorField1,sensorField2
        , ROW_NUMBER() OVER(
            PARTITION BY sensorID
            ORDER BY timestamp
        ) AS rn
    FROM sensorTable s1
WHERE rn = 1
ORDER BY sensorID, timestamp;

I acually use this more than correlated sub-queries. Feel free to bust me in the comments over effeciancy, I'm not too sure how it stacks up in that regard.

const log = chrome.extension.getBackgroundPage().console.log;
log('something')

Open log:

• Open: chrome://extensions/
• Details > Background page

document.getElementById("id").innerHTML == "" || null

or

$("element").html() == "" || null

You can use the is_cart() conditional tag:

if (! is_cart() ) {
  // Do something.
}

Html5 also recommend to use <html lang="es-ES"> The small letter lang tag only specifies: language code The large letter specifies: country code

This is really useful for ie.Chrome, when the browser is proposing to translate web content(ie google translate)

Last insert id means you can get inserted auto increment id by using this method in active record,

$this->db->insert_id() 
// it can be return insert id it is 
// similar to the mysql_insert_id in core PHP

You can refer this link you can find some more stuff.

Information from executing a query

Here's a more general technique for left-padding to any desired width:

declare @x     int     = 123 -- value to be padded
declare @width int     = 25  -- desired width
declare @pad   char(1) = '0' -- pad character

select right_justified = replicate(
                           @pad ,
                           @width-len(convert(varchar(100),@x))
                           )
                       + convert(varchar(100),@x)

However, if you're dealing with negative values, and padding with leading zeroes, neither this, nor other suggested technique will work. You'll get something that looks like this:

00-123

[Probably not what you wanted]

So … you'll have to jump through some additional hoops Here's one approach that will properly format negative numbers:

declare @x     float   = -1.234
declare @width int     = 20
declare @pad   char(1) = '0'

select right_justified = stuff(
         convert(varchar(99),@x) ,                            -- source string (converted from numeric value)
         case when @x < 0 then 2 else 1 end ,                 -- insert position
         0 ,                                                  -- count of characters to remove from source string
         replicate(@pad,@width-len(convert(varchar(99),@x)) ) -- text to be inserted
         )

One should note that the convert() calls should specify an [n]varchar of sufficient length to hold the converted result with truncation.

You can use the ast module and write a NodeVisitor that verifies that the type of each node is part of a whitelist.

import ast, math

locals =  {key: value for (key,value) in vars(math).items() if key[0] != '_'}
locals.update({"abs": abs, "complex": complex, "min": min, "max": max, "pow": pow, "round": round})

class Visitor(ast.NodeVisitor):
    def visit(self, node):
       if not isinstance(node, self.whitelist):
           raise ValueError(node)
       return super().visit(node)

    whitelist = (ast.Module, ast.Expr, ast.Load, ast.Expression, ast.Add, ast.Sub, ast.UnaryOp, ast.Num, ast.BinOp,
            ast.Mult, ast.Div, ast.Pow, ast.BitOr, ast.BitAnd, ast.BitXor, ast.USub, ast.UAdd, ast.FloorDiv, ast.Mod,
            ast.LShift, ast.RShift, ast.Invert, ast.Call, ast.Name)

def evaluate(expr, locals = {}):
    if any(elem in expr for elem in '\n#') : raise ValueError(expr)
    try:
        node = ast.parse(expr.strip(), mode='eval')
        Visitor().visit(node)
        return eval(compile(node, "<string>", "eval"), {'__builtins__': None}, locals)
    except Exception: raise ValueError(expr)

Because it works via a whitelist rather than a blacklist, it is safe. The only functions and variables it can access are those you explicitly give it access to. I populated a dict with math-related functions so you can easily provide access to those if you want, but you have to explicitly use it.

If the string attempts to call functions that haven't been provided, or invoke any methods, an exception will be raised, and it will not be executed.

Because this uses Python's built in parser and evaluator, it also inherits Python's precedence and promotion rules as well.

>>> evaluate("7 + 9 * (2 << 2)")
79
>>> evaluate("6 // 2 + 0.0")
3.0

The above code has only been tested on Python 3.

If desired, you can add a timeout decorator on this function.

In my somewhat checkered experience, applying -O3 to an entire program almost always makes it slower (relative to -O2), because it turns on aggressive loop unrolling and inlining that make the program no longer fit in the instruction cache. For larger programs, this can also be true for -O2 relative to -Os!

The intended use pattern for -O3 is, after profiling your program, you manually apply it to a small handful of files containing critical inner loops that actually benefit from these aggressive space-for-speed tradeoffs. Newer versions of GCC have a profile-guided optimization mode that can (IIUC) selectively apply the -O3 optimizations to hot functions -- effectively automating this process.

If you really don't want to change your structure, or at least create a copy of it containing the same data (e.g. make a class property with a setter and getter that read from/write to that string behind the scenes), then you can use a regular expression to check if an item is in that "list" at any given time, and if not, append it to the "list" as a separate element.

if not re.match("\b{}\b".format(348521), some_list[0]): some_list.append(348521)

This is probably faster than converting it to a set every time you want to check if an item is in it. But using set as others have suggested here is a million times better.

If it returns "this.state is undefined" - bind timer function:

constructor(props){
    super(props);
    this.state = {currentCount: 10}
    this.timer = this.timer.bind(this)
}

On most POSIX systems, it is ignored. But, check your system to be sure.

The mode string can also include the letter 'b' either as last character or as a character between the characters in any of the two-character strings described above. This is strictly for compatibility with ISO/IEC 9899:1990 ('ISO C90') and has no effect; the 'b' is ignored.

Linux

The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two- character strings described above. This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux. (Other systems may treat text files and binary files differently, and adding the 'b' may be a good idea if you do I/O to a binary file and expect that your program may be ported to non-UNIX environments.)

If you right-click on your "Computer" (or "My Computer") icon and select "Manage" from the pop-up menu, that'll take you to the Computer Management console.

In there, under System Tools\Shared Folders, you'll find "Open Files". This is probably close to what you want, but if the file is on a network share then you'd need to do the same thing on the server on which the file lives.

Since you rarely need sorting, as per your problem statement, this is probably more efficient than it needs to be.

Use a loop on the split values

string values = "0,1,2,3,4,5,6,7,8,9";

foreach(string value in values.split(','))
{
    //do something with individual value
}

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

create div with id name

var divCreator=function (id){
newElement=document.createElement("div");
newNode=document.body.appendChild(newElement);
newNode.setAttribute("id",id);
}

add text to div

var textAdder = function(id, text) {
target = document.getElementById(id)
target.appendChild(document.createTextNode(text));
}

test code

divCreator("div1");
textAdder("div1", "this is paragraph 1");

output

this is paragraph 1

For MongoDB shell version 3.0.5 insert the following command in the shell:

db.adminCommand('listDatabases')

or alternatively:

db.getMongo().getDBNames()

There's parameter substitution, though it may be un-PC as well ...like indirection.

#!/bin/bash

# Array pretending to be a Pythonic dictionary
ARRAY=( "cow:moo"
        "dinosaur:roar"
        "bird:chirp"
        "bash:rock" )

for animal in "${ARRAY[@]}" ; do
    KEY="${animal%%:*}"
    VALUE="${animal##*:}"
    printf "%s likes to %s.\n" "$KEY" "$VALUE"
done

printf "%s is an extinct animal which likes to %s\n" "${ARRAY[1]%%:*}" "${ARRAY[1]##*:}"

The BASH 4 way is better of course, but if you need a hack ...only a hack will do. You could search the array/hash with similar techniques.

What is this for and why would I use @":\" instead of ":\"?

Because when you have a long string with many \ you don't need to escape them all and the \n, \r and \f won't work too.

Simple workaround - just use hidden field as placeholder for select, checkbox and radio.

From this code to -

<form action="/Media/Add">
    <input type="hidden" name="Id" value="123" />

    <!-- this does not appear in request -->
    <input type="textbox" name="Percentage" value="100" disabled="disabled" /> 
    <select name="gender" disabled="disabled">
          <option value="male">Male</option>
          <option value="female" selected>Female</option>
    </select>

</form>

that code -

<form action="/Media/Add">
    <input type="hidden" name="Id" value="123" />

    <input type="textbox" value="100" readonly /> 

    <input type="hidden" name="gender" value="female" />
    <select name="gender" disabled="disabled">
          <option value="male">Male</option>
          <option value="female" selected>Female</option>
    </select>
</form>

From the official Swift programming guide:

Global variables are variables that are defined outside of any function, method, closure, or type context. Global constants and variables are always computed lazily.

You can define it in any file and can access it in current module anywhere. So you can define it somewhere in the file outside of any scope. There is no need for static and all global variables are computed lazily.

 var yourVariable = "someString"

You can access this from anywhere in the current module.

However you should avoid this as Global variables are not good for application state and mainly reason of bugs.

As shown in this answer, in Swift you can encapsulate them in struct and can access anywhere. You can define static variables or constant in Swift also. Encapsulate in struct

struct MyVariables {
    static var yourVariable = "someString"
}

You can use this variable in any class or anywhere

let string = MyVariables.yourVariable
println("Global variable:\(string)")

//Changing value of it
MyVariables.yourVariable = "anotherString"

Give your radiobutton a custom style:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:button">@drawable/custom_btn_radio</item>
</style>

custom_btn_radio.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
          android:drawable="@drawable/btn_radio_on" />
    <item android:state_checked="false" android:state_window_focused="false"
          android:drawable="@drawable/btn_radio_off" />

    <item android:state_checked="true" android:state_pressed="true"
          android:drawable="@drawable/btn_radio_on_pressed" />
    <item android:state_checked="false" android:state_pressed="true"
          android:drawable="@drawable/btn_radio_off_pressed" />

    <item android:state_checked="true" android:state_focused="true"
          android:drawable="@drawable/btn_radio_on_selected" />
    <item android:state_checked="false" android:state_focused="true"
          android:drawable="@drawable/btn_radio_off_selected" />

    <item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />
    <item android:state_checked="true" android:drawable="@drawable/btn_radio_on" />
</selector>

Replace the drawables with your own.

As promised, I'm putting an example for how to use annotations to serialize/deserialize polymorphic objects, I based this example in the Animal class from the tutorial you were reading.

First of all your Animal class with the Json Annotations for the subclasses.

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY)
@JsonSubTypes({
    @JsonSubTypes.Type(value = Dog.class, name = "Dog"),

    @JsonSubTypes.Type(value = Cat.class, name = "Cat") }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

Then your subclasses, Dog and Cat.

public class Dog extends Animal {

    private String breed;

    public Dog() {

    }

    public Dog(String name, String breed) {
        setName(name);
        setBreed(breed);
    }

    public String getBreed() {
        return breed;
    }

    public void setBreed(String breed) {
        this.breed = breed;
    }
}

public class Cat extends Animal {

    public String getFavoriteToy() {
        return favoriteToy;
    }

    public Cat() {}

    public Cat(String name, String favoriteToy) {
        setName(name);
        setFavoriteToy(favoriteToy);
    }

    public void setFavoriteToy(String favoriteToy) {
        this.favoriteToy = favoriteToy;
    }

    private String favoriteToy;

}

As you can see, there is nothing special for Cat and Dog, the only one that know about them is the abstract class Animal, so when deserializing, you'll target to Animal and the ObjectMapper will return the actual instance as you can see in the following test:

public class Test {

    public static void main(String[] args) {

        ObjectMapper objectMapper = new ObjectMapper();

        Animal myDog = new Dog("ruffus","english shepherd");

        Animal myCat = new Cat("goya", "mice");

        try {
            String dogJson = objectMapper.writeValueAsString(myDog);

            System.out.println(dogJson);

            Animal deserializedDog = objectMapper.readValue(dogJson, Animal.class);

            System.out.println("Deserialized dogJson Class: " + deserializedDog.getClass().getSimpleName());

            String catJson = objectMapper.writeValueAsString(myCat);

            Animal deseriliazedCat = objectMapper.readValue(catJson, Animal.class);

            System.out.println("Deserialized catJson Class: " + deseriliazedCat.getClass().getSimpleName());



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

    }
}

Output after running the Test class:

{"@type":"Dog","name":"ruffus","breed":"english shepherd"}

Deserialized dogJson Class: Dog

{"@type":"Cat","name":"goya","favoriteToy":"mice"}

Deserialized catJson Class: Cat

Hope this helps,

I ran into this while building for Tests. Build to Run works fine. Xcode 7/Swift 2 didn't like the way a variable was initialized. This code ran fine in Xcode 6.4. Here's the line that caused the seg fault:

var lineWidth: CGFloat = (UIScreen.mainScreen().scale == 1.0) ? 1.0 : 0.5

Changing it to this solved the problem:

var lineWidth: CGFloat {
    return (UIScreen.mainScreen().scale == 1.0) ? 1.0 : 0.5
}

strcat attempts to append the second parameter to the first. This won't work since you are assigning implicitly sized constant strings.

If all you want to do is print two strings out

printf("%s%s",str1,str2);

Would do.

You could do something like

char *str1 = calloc(sizeof("SSSS")+sizeof("KKKK")+1,sizeof *str1);
strcpy(str1,"SSSS");
strcat(str1,str2);

to create a concatenated string; however strongly consider using strncat/strncpy instead. And read the man pages carefully for the above. (oh and don't forget to free str1 at the end).

In order to avoid having to fully specify the git push command you could alternatively modify your git config file:

[remote "gerrit"]
    url = https://your.gerrit.repo:44444/repo
    fetch = +refs/heads/master:refs/remotes/origin/master
    push = refs/heads/master:refs/for/master

Now you can simply:

git fetch gerrit
git push gerrit

This is according to Gerrit

By doing so you'd be able to control any action of the framed page, which you cannot. Same-domain origin policy applies.

Thank you for your help. At last I could draw a line on the map. This is how I done it:

/** Called when the activity is first created. */
private List<Overlay> mapOverlays;

private Projection projection;  

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    linearLayout = (LinearLayout) findViewById(R.id.zoomview);
    mapView = (MapView) findViewById(R.id.mapview);
    mapView.setBuiltInZoomControls(true);

    mapOverlays = mapView.getOverlays();        
    projection = mapView.getProjection();
    mapOverlays.add(new MyOverlay());        

}

@Override
protected boolean isRouteDisplayed() {
    return false;
}

class MyOverlay extends Overlay{

    public MyOverlay(){

    }   

    public void draw(Canvas canvas, MapView mapv, boolean shadow){
        super.draw(canvas, mapv, shadow);

        Paint   mPaint = new Paint();
        mPaint.setDither(true);
        mPaint.setColor(Color.RED);
        mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
        mPaint.setStrokeJoin(Paint.Join.ROUND);
        mPaint.setStrokeCap(Paint.Cap.ROUND);
        mPaint.setStrokeWidth(2);

        GeoPoint gP1 = new GeoPoint(19240000,-99120000);
        GeoPoint gP2 = new GeoPoint(37423157, -122085008);

        Point p1 = new Point();
        Point p2 = new Point();
        Path path = new Path();

        Projection projection=mapv.getProjection();
        projection.toPixels(gP1, p1);
        projection.toPixels(gP2, p2);

        path.moveTo(p2.x, p2.y);
        path.lineTo(p1.x,p1.y);

        canvas.drawPath(path, mPaint);
    }

To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.

SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC

If you care for it to be in the same order as before you can use a common table expression for that:

;WITH CTE AS (
    SELECT TOP 1000 *
    FROM [SomeTable]
    ORDER BY MySortColumn DESC
)

SELECT * 
FROM CTE

For completeness these are the cmap choices I encountered so far:

Now on the Smartgit webpage (I don't know since when) there is the possibility to download directly the .deb package. Once installed, it will upgrade automagically itself when a new version is released.

If you use fragments you can prepare XML layout and than stratch critical elements programmatically

int thirdScreenWidth = (int)(screenWidth *0.33);

View view = inflater.inflate(R.layout.fragment_second, null);
View _container = view.findViewById(R.id.rim1container);
_container.getLayoutParams().width = thirdScreenWidth * 2;

_container = view.findViewById(R.id.rim2container);
_container.getLayoutParams().width = screenWidth - thirdScreenWidth * 2;

_container = view.findViewById(R.id.rim3container);
_container.getLayoutParams().width = screenWidth - thirdScreenWidth * 2;

This layout for 3 equal columns. First element takes 2x2 Result in the picture

The question mark is the conditional operator. The code means that if f==r then 1 is returned, otherwise, return 0. The code could be rewritten as

int qempty()
{
  if(f==r)
    return 1;
  else
    return 0;
}

which is probably not the cleanest way to do it, but hopefully helps your understanding.

Objects are instances of classes. Classes are just the blueprints for objects. So given your class definition -

# Note the added (object) - this is the preferred way of creating new classes
class Student(object):
    name = "Unknown name"
    age = 0
    major = "Unknown major"

You can create a make_student function by explicitly assigning the attributes to a new instance of Student -

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    return student

But it probably makes more sense to do this in a constructor (__init__) -

class Student(object):
    def __init__(self, name="Unknown name", age=0, major="Unknown major"):
        self.name = name
        self.age = age
        self.major = major

The constructor is called when you use Student(). It will take the arguments defined in the __init__ method. The constructor signature would now essentially be Student(name, age, major).

If you use that, then a make_student function is trivial (and superfluous) -

def make_student(name, age, major):
    return Student(name, age, major)

For fun, here is an example of how to create a make_student function without defining a class. Please do not try this at home.

def make_student(name, age, major):
    return type('Student', (object,),
                {'name': name, 'age': age, 'major': major})()

I know it's an old question, but maybe it helps someone to call stored procedures without adding DTOs as DbSets.

To: Killercam Thanks for your solutions. I tried the first solution for an hour, but didn't work for me.

I used scripts generate method to move data from SQL Server 2012 to SQL Server 2008 R2 as steps bellow:

In the 2012 SQL Management Studio

1. Tasks -> Generate Scripts (in first wizard screen, click Next - may not show)
2. Choose Script entire database and all database objects -> Next
3. Click [Advanced] button 3.1 Change [Types of data to script] from "Schema only" to "Schema and data" 3.2 Change [Script for Server Version] "2012" to "2008"
4. Finish next wizard steps for creating script file
5. Use sqlcmd to import the exported script file to your SQL Server 2008 R2 5.1 Open windows command line 5.2 Type [sqlcmd -S -i Path to your file] (Ex: [sqlcmd -S localhost -i C:\mydatabase.sql])

It works for me.

Recently I started using the Mac Pc for android development. When I go to

Android Studio => File => Other setting => Preference for New Projects..

I was not able to find plugin option in the setting page.

Later while clicking option on the toolbar, I clicked on "SDK Manager" it prompted the Settings where the Plugin option was visible and I was able to add the plugins from here.

After this, it opens the following setting
