In order to match a digit, you can use [0-9].

So you could use 5[0-9][0-9][0-9][0-9][0-9][0-9] and [0-9][0-9][0-9][0-9]7[0-9][0-9][0-9]. I do this a lot for zip codes.

This worked for me:

window.location.replace(window.location.pathname)

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

I know this question already has an accepted answer, but for me, a .NET beginner, there was a simple solution to what I was doing wrong and I thought I'd share.

I had been doing this:

@Html.HiddenFor(Model.Foo.Bar.ID)

What worked for me was changing to this:

@Html.HiddenFor(m => m.Foo.Bar.ID)

(where "m" is an arbitrary string to represent the model object)

You can use Expression.AndAlso / OrElse to combine logical expressions, but you have to make sure the ParameterExpressions are the same.

I was having trouble with EF and the PredicateBuilder so I made my own without resorting to Invoke, that I could use like this:

var filterC = filterA.And(filterb);

Source code for my PredicateBuilder:

public static class PredicateBuilder {

    public static Expression<Func<T, bool>> And<T>(this Expression<Func<T, bool>> a, Expression<Func<T, bool>> b) {    

        ParameterExpression p = a.Parameters[0];

        SubstExpressionVisitor visitor = new SubstExpressionVisitor();
        visitor.subst[b.Parameters[0]] = p;

        Expression body = Expression.AndAlso(a.Body, visitor.Visit(b.Body));
        return Expression.Lambda<Func<T, bool>>(body, p);
    }

    public static Expression<Func<T, bool>> Or<T>(this Expression<Func<T, bool>> a, Expression<Func<T, bool>> b) {    

        ParameterExpression p = a.Parameters[0];

        SubstExpressionVisitor visitor = new SubstExpressionVisitor();
        visitor.subst[b.Parameters[0]] = p;

        Expression body = Expression.OrElse(a.Body, visitor.Visit(b.Body));
        return Expression.Lambda<Func<T, bool>>(body, p);
    }   
}

And the utility class to substitute the parameters in a lambda:

internal class SubstExpressionVisitor : System.Linq.Expressions.ExpressionVisitor {
        public Dictionary<Expression, Expression> subst = new Dictionary<Expression, Expression>();

        protected override Expression VisitParameter(ParameterExpression node) {
            Expression newValue;
            if (subst.TryGetValue(node, out newValue)) {
                return newValue;
            }
            return node;
        }
    }

So we make a function that takes in a literal string, and the array we want to look through. it returns a new array with the matches found. We create a new regexp object inside this function and then execute a String.search on each element element in the array. If found, it pushes the string into a new array and returns.

// literal_string: a regex search, like /thisword/ig
// target_arr: the array you want to search /thisword/ig for.

function arr_grep(literal_string, target_arr) {
  var match_bin = [];
  // o_regex: a new regex object.
  var o_regex = new RegExp(literal_string);
  for (var i = 0; i < target_arr.length; i++) {
    //loop through array. regex search each element.
    var test = String(target_arr[i]).search(o_regex);
    if (test > -1) {
    // if found push the element@index into our matchbin.
    match_bin.push(target_arr[i]);
    }
  }
  return match_bin;
}

// arr_grep(/.*this_word.*/ig, someArray)

Select the text of all items under produce:

//produce/item/text()

Select all the manager nodes in all departments:

//department/*

I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans, not conditionals. If I need both conditional and boolean logic, I prefer to put in the conditional logic using ng-if as the first check, then add in an additional check for the boolean logic with ng-show and ng-hide

Howerver, if you want to use a conditional for ng-show or ng-hide, here is a link with some examples: Conditional Display using ng-if, ng-show, ng-hide, ng-include, ng-switch

To remove all non-ASCII characters, you can use following replacement: [^\x00-\x7F]+

To highlight characters, I recommend using the Mark function in the search window: this highlights non-ASCII characters and put a bookmark in the lines containing one of them

If you want to highlight and put a bookmark on the ASCII characters instead, you can use the regex [\x00-\x7F] to do so.

Cheers

A variation when using xpath in Java using count():

int numberofbodies = Integer.parseInt((String) xPath.evaluate("count(/html/body)", doc));
if( numberofbodies==0) {
    // body node missing
}

Expressions only contain identifiers, literals and operators, where operators include arithmetic and boolean operators, the function call operator () the subscription operator [] and similar, and can be reduced to some kind of "value", which can be any Python object. Examples:

3 + 5
map(lambda x: x*x, range(10))
[a.x for a in some_iterable]
yield 7

Statements (see 1, 2), on the other hand, are everything that can make up a line (or several lines) of Python code. Note that expressions are statements as well. Examples:

# all the above expressions
print 42
if x: do_y()
return
a = 7

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

List<AnalysisObject> analysisObjects = analysisObjectRepository

                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

Use this live online example to test your pattern:

Above screenshot taken from this live example: https://regex101.com/r/cU5lC2/1

Matching any whole word on the commandline.

I'll be using the phpsh interactive shell on Ubuntu 12.10 to demonstrate the PCRE regex engine through the method known as preg_match

Start phpsh, put some content into a variable, match on word.

el@apollo:~/foo$ phpsh

php> $content1 = 'badger'
php> $content2 = '1234'
php> $content3 = '$%^&'

php> echo preg_match('(\w+)', $content1);
1

php> echo preg_match('(\w+)', $content2);
1

php> echo preg_match('(\w+)', $content3);
0

The preg_match method used the PCRE engine within the PHP language to analyze variables: $content1, $content2 and $content3 with the (\w)+ pattern.

$content1 and $content2 contain at least one word, $content3 does not.

Match a specific words on the commandline without word bountaries

el@apollo:~/foo$ phpsh

php> $gun1 = 'dart gun';
php> $gun2 = 'fart gun';
php> $gun3 = 'darty gun';
php> $gun4 = 'unicorn gun';

php> echo preg_match('(dart|fart)', $gun1);
1

php> echo preg_match('(dart|fart)', $gun2);
1

php> echo preg_match('(dart|fart)', $gun3);
1

php> echo preg_match('(dart|fart)', $gun4);
0

Variables gun1 and gun2 contain the string dart or fart which is correct, but gun3 contains darty and still matches, that is the problem. So onto the next example.

Match specific words on the commandline with word boundaries:

Word Boundaries can be force matched with \b, see:

Regex Visual Image acquired from http://jex.im/regulex and https://github.com/JexCheng/regulex Example:

el@apollo:~/foo$ phpsh

php> $gun1 = 'dart gun';
php> $gun2 = 'fart gun';
php> $gun3 = 'darty gun';
php> $gun4 = 'unicorn gun';

php> echo preg_match('(\bdart\b|\bfart\b)', $gun1);
1

php> echo preg_match('(\bdart\b|\bfart\b)', $gun2);
1

php> echo preg_match('(\bdart\b|\bfart\b)', $gun3);
0

php> echo preg_match('(\bdart\b|\bfart\b)', $gun4);
0

The \b asserts that we have a word boundary, making sure " dart " is matched, but " darty " isn't.

Just use DateValue(Now) if you want the result to be of DateTime data type.

IMHO, the best explanation about its meaning gave us Stroustrup + take into account examples of Dániel Sándor and Mohan:

Stroustrup:

Now I was seriously worried. Clearly we were headed for an impasse or a mess or both. I spent the lunchtime doing an analysis to see which of the properties (of values) were independent. There were only two independent properties:

• has identity – i.e. and address, a pointer, the user can determine whether two copies are identical, etc.
• can be moved from – i.e. we are allowed to leave to source of a "copy" in some indeterminate, but valid state

This led me to the conclusion that there are exactly three kinds of values (using the regex notational trick of using a capital letter to indicate a negative – I was in a hurry):

• iM: has identity and cannot be moved from
• im: has identity and can be moved from (e.g. the result of casting an lvalue to a rvalue reference)

• Im: does not have identity and can be moved from.

  The fourth possibility, IM, (doesn’t have identity and cannot be moved) is not useful in C++ (or, I think) in any other language.

In addition to these three fundamental classifications of values, we have two obvious generalizations that correspond to the two independent properties:

• i: has identity
• m: can be moved from

This led me to put this diagram on the board:

Naming

I observed that we had only limited freedom to name: The two points to the left (labeled iM and i) are what people with more or less formality have called lvalues and the two points on the right (labeled m and Im) are what people with more or less formality have called rvalues. This must be reflected in our naming. That is, the left "leg" of the W should have names related to lvalue and the right "leg" of the W should have names related to rvalue. I note that this whole discussion/problem arise from the introduction of rvalue references and move semantics. These notions simply don’t exist in Strachey’s world consisting of just rvalues and lvalues. Someone observed that the ideas that

• Every value is either an lvalue or an rvalue
• An lvalue is not an rvalue and an rvalue is not an lvalue

are deeply embedded in our consciousness, very useful properties, and traces of this dichotomy can be found all over the draft standard. We all agreed that we ought to preserve those properties (and make them precise). This further constrained our naming choices. I observed that the standard library wording uses rvalue to mean m (the generalization), so that to preserve the expectation and text of the standard library the right-hand bottom point of the W should be named rvalue.

This led to a focused discussion of naming. First, we needed to decide on lvalue. Should lvalue mean iM or the generalization i? Led by Doug Gregor, we listed the places in the core language wording where the word lvalue was qualified to mean the one or the other. A list was made and in most cases and in the most tricky/brittle text lvalue currently means iM. This is the classical meaning of lvalue because "in the old days" nothing was moved; move is a novel notion in C++0x. Also, naming the topleft point of the W lvalue gives us the property that every value is an lvalue or an rvalue, but not both.

So, the top left point of the W is lvalue and the bottom right point is rvalue. What does that make the bottom left and top right points? The bottom left point is a generalization of the classical lvalue, allowing for move. So it is a generalized lvalue. We named it glvalue. You can quibble about the abbreviation, but (I think) not with the logic. We assumed that in serious use generalized lvalue would somehow be abbreviated anyway, so we had better do it immediately (or risk confusion). The top right point of the W is less general than the bottom right (now, as ever, called rvalue). That point represent the original pure notion of an object you can move from because it cannot be referred to again (except by a destructor). I liked the phrase specialized rvalue in contrast to generalized lvalue but pure rvalue abbreviated to prvalue won out (and probably rightly so). So, the left leg of the W is lvalue and glvalue and the right leg is prvalue and rvalue. Incidentally, every value is either a glvalue or a prvalue, but not both.

This leaves the top middle of the W: im; that is, values that have identity and can be moved. We really don’t have anything that guides us to a good name for those esoteric beasts. They are important to people working with the (draft) standard text, but are unlikely to become a household name. We didn’t find any real constraints on the naming to guide us, so we picked ‘x’ for the center, the unknown, the strange, the xpert only, or even x-rated.

But I need the match result to be ... not in a match group...

For what you are trying to do, this should work. \K resets the starting point of the match.

\bObject Name:\s+\K\S+

You can do the same for getting your Security ID matches.

\bSecurity ID:\s+\K\S+

You should be able to use

IIF(Fields!ExitReason.Value = 7, 1, 0)

The assignment expression operator := added in Python 3.8 supports assignment inside of lambda expressions. This operator can only appear within a parenthesized (...), bracketed [...], or braced {...} expression for syntactic reasons. For example, we will be able to write the following:

import sys
say_hello = lambda: (
    message := "Hello world",
    sys.stdout.write(message + "\n")
)[-1]
say_hello()

In Python 2, it was possible to perform local assignments as a side effect of list comprehensions.

import sys
say_hello = lambda: (
    [None for message in ["Hello world"]],
    sys.stdout.write(message + "\n")
)[-1]
say_hello()

However, it's not possible to use either of these in your example because your variable flag is in an outer scope, not the lambda's scope. This doesn't have to do with lambda, it's the general behaviour in Python 2. Python 3 lets you get around this with the nonlocal keyword inside of defs, but nonlocal can't be used inside lambdas.

There's a workaround (see below), but while we're on the topic...

In some cases you can use this to do everything inside of a lambda:

(lambda: [
    ['def'
        for sys in [__import__('sys')]
        for math in [__import__('math')]

        for sub in [lambda *vals: None]
        for fun in [lambda *vals: vals[-1]]

        for echo in [lambda *vals: sub(
            sys.stdout.write(u" ".join(map(unicode, vals)) + u"\n"))]

        for Cylinder in [type('Cylinder', (object,), dict(
            __init__ = lambda self, radius, height: sub(
                setattr(self, 'radius', radius),
                setattr(self, 'height', height)),

            volume = property(lambda self: fun(
                ['def' for top_area in [math.pi * self.radius ** 2]],

                self.height * top_area))))]

        for main in [lambda: sub(
            ['loop' for factor in [1, 2, 3] if sub(
                ['def'
                    for my_radius, my_height in [[10 * factor, 20 * factor]]
                    for my_cylinder in [Cylinder(my_radius, my_height)]],

                echo(u"A cylinder with a radius of %.1fcm and a height "
                     u"of %.1fcm has a volume of %.1fcm³."
                     % (my_radius, my_height, my_cylinder.volume)))])]],

    main()])()

A cylinder with a radius of 10.0cm and a height of 20.0cm has a volume of 6283.2cm³.
A cylinder with a radius of 20.0cm and a height of 40.0cm has a volume of 50265.5cm³.
A cylinder with a radius of 30.0cm and a height of 60.0cm has a volume of 169646.0cm³.

Please don't.

...back to your original example: though you can't perform assignments to the flag variable in the outer scope, you can use functions to modify the previously-assigned value.

For example, flag could be an object whose .value we set using setattr:

flag = Object(value=True)
input = [Object(name=''), Object(name='fake_name'), Object(name='')] 
output = filter(lambda o: [
    flag.value or bool(o.name),
    setattr(flag, 'value', flag.value and bool(o.name))
][0], input)

[Object(name=''), Object(name='fake_name')]

If we wanted to fit the above theme, we could use a list comprehension instead of setattr:

    [None for flag.value in [bool(o.name)]]

But really, in serious code you should always use a regular function definition instead of a lambda if you're going to be doing outer assignment.

flag = Object(value=True)
def not_empty_except_first(o):
    result = flag.value or bool(o.name)
    flag.value = flag.value and bool(o.name)
    return result
input = [Object(name=""), Object(name="fake_name"), Object(name="")] 
output = filter(not_empty_except_first, input)

I believe it would be like this

takedata.match(/(\[.+\])/g);

the g at the end means global, so it doesn't stop at the first match.

This is the way I would do it : saying that "list" is a <List<t>> where t is a class with a Name and a Value field; but of course you can do it with any other class type.

    list = list.Where(c=>c.Name == "height")
        .Select( new t(){Name = c.Name, Value = 30})
        .Union(list.Where(c=> c.Name != "height"))
        .ToList();

This works perfectly ! It's a simple linq expression without any loop logic. The only thing you should be aware is that the order of the lines in the result dataset will be different from the order you had in the source dataset. So if sorting is important to you, just reproduce the same order by clauses in the final linq query.

Another trick not yet mentioned is to have the class which implements a property (e.g. Foo of type Bar) also define a delegate delegate void ActByRef<T1,T2>(ref T1 p1, ref T2 p2); and implement a method ActOnFoo<TX1>(ref Bar it, ActByRef<Bar,TX1> proc, ref TX1 extraParam1) (and possibly versions for two and three "extra parameters" as well) which will pass its internal representation of Foo to the supplied procedure as a ref parameter. This has a couple of big advantages over other methods of working with the property:

1. The property is updated "in place"; if the property is of a type that's compatible with `Interlocked` methods, or if it is a struct with exposed fields of such types, the `Interlocked` methods may be used to perform atomic updates to the property.
2. If the property is an exposed-field structure, the fields of the structure may be modified without having to make any redundant copies of it.
3. If the `ActByRef` method passes one or more `ref` parameters through from its caller to the supplied delegate, it may be possible to use a singleton or static delegate, thus avoiding the need to create closures or delegates at run-time.
4. The property knows when it is being "worked with". While it is always necessary to use caution executing external code while holding a lock, if one can trust callers not to do too do anything in their callback that might require another lock, it may be practical to have the method guard the property access with a lock, such that updates which aren't compatible with `CompareExchange` could still be performed quasi-atomically.

Passing things be ref is an excellent pattern; too bad it's not used more.

My experience of XmlReader is that it's very easy to accidentally read too much. I know you've said you want to read it as quickly as possible, but have you tried using a DOM model instead? I've found that LINQ to XML makes XML work much much easier.

If your document is particularly huge, you can combine XmlReader and LINQ to XML by creating an XElement from an XmlReader for each of your "outer" elements in a streaming manner: this lets you do most of the conversion work in LINQ to XML, but still only need a small portion of the document in memory at any one time. Here's some sample code (adapted slightly from this blog post):

static IEnumerable<XElement> SimpleStreamAxis(string inputUrl,
                                              string elementName)
{
  using (XmlReader reader = XmlReader.Create(inputUrl))
  {
    reader.MoveToContent();
    while (reader.Read())
    {
      if (reader.NodeType == XmlNodeType.Element)
      {
        if (reader.Name == elementName)
        {
          XElement el = XNode.ReadFrom(reader) as XElement;
          if (el != null)
          {
            yield return el;
          }
        }
      }
    }
  }
}

I've used this to convert the StackOverflow user data (which is enormous) into another format before - it works very well.

EDIT from radarbob, reformatted by Jon - although it's not quite clear which "read too far" problem is being referred to...

This should simplify the nesting and take care of the "a read too far" problem.

using (XmlReader reader = XmlReader.Create(inputUrl))
{
    reader.ReadStartElement("theRootElement");

    while (reader.Name == "TheNodeIWant")
    {
        XElement el = (XElement) XNode.ReadFrom(reader);
    }

    reader.ReadEndElement();
}

This takes care of "a read too far" problem because it implements the classic while loop pattern:

initial read;
(while "we're not at the end") {
    do stuff;
    read;
}

py2exe will make the EXE file you want, but you need to have the same version of MSVCR90.dll on the machine you're going to use your new EXE file.

See Tutorial for more information.

find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash

bash 4 (recursive)

shopt -s globstar
for xls in /path/**/*.xls
do
  xls2csv "$xls" "${xls%.xls}.csv"
done

You need to check for status 0 (as when loading files locally with XMLHttpRequest, you don't get a status and if it is from web server it returns the status)

function readTextFile(file) {
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
    if(rawFile.readyState === 4)
    {
        if(rawFile.status === 200 || rawFile.status == 0)
        {
            var allText = rawFile.responseText;
            alert(allText);
        }
    }
}
rawFile.send(null);

}

For device file readuing use this:

readTextFile("file:///C:/your/path/to/file.txt");

For file reading from server use:

readTextFile("http://test/file.txt");

ISO compliant dateString

If your dateString is RFC282 and ISO8601 compliant:
pass your string into the Date Constructor:

const dateString = "2020-10-30T12:52:27+05:30"; // ISO8601 compliant dateString
const D = new Date(dateString);                 // {object Date}

from here you can extract the desired values by using Date Getters:

D.getMonth() + 1  // 10 (PS: +1 since Month is 0-based)
D.getDate()       // 30
D.getFullYear()   // 2020

Non-standard date string

If you use a non standard date string:
destructure the string into known parts, and than pass the variables to the Date Constructor:

new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]])

const dateString = "30/10/2020 12:52:27";
const [d, M, y, h, m, s] = dateString.match(/\d+/g);

// PS: M-1 since Month is 0-based
const D = new Date(y, M-1, d, h, m, s);  // {object Date}


D.getMonth() + 1  // 10 (PS: +1 since Month is 0-based)
D.getDate()       // 30
D.getFullYear()   // 2020

For positive numbers:

    q = x/y + (x % y != 0);

In addition to doing the following, you may experience this issue if your app's Storyboard's files are localized. First, do each of these:

• Clean Build
• Reset Simulator

What finally worked for me was re-generating the storyboard localization files and deleting the English localization (which was unneeded because the Base Locale is English). To reload your Storyboard strings, see this answer on StackOverflow.

I had noticed that the non-text parts of my Storyboard were being updated, but not the localized text. If you have a localization in your app, I would recommend checking to make sure your localizations are updated (even if they're .strings files).

As others have said, you can't do that either using alert()or confirm().

You can, however, create an external HTML document containing your error message and an OK button, set its <title> element to whatever you want, then display it in a modal dialog box using showModalDialog().

You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

SQL Books Online should contain lots of information about the records it returns.

For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job

• msdb.dbo.SysJobs
• msdb.dbo.SysJobSteps
• msdb.dbo.SysJobSchedules
• msdb.dbo.SysJobServers
• msdb.dbo.SysJobHistory

Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).

Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs

Try

let str ="554,20";_x000D_
let float = +str.replace(',','.');_x000D_
let int = str.split(',').map(x=>+x);_x000D_
_x000D_
console.log({float,int});

start xxx.py

You can use this for some other file types.

Answer is NO. You might have seen an example where somebody would have set something like :

-DArguments=a=1,b=2,c=3,d=4,e=cow

Then the application would parse value of Arguments property string to get individual values. In your main you can get the key values as(Assuming input format is guaranteed):

String line = System.getProperty("Arguments");
if(line != null) {
  String str[] = line.split(",");
    for(int i=1;i<str.length;i++){
        String arr[] = str[i].split("=");
        System.out.println("Key = " + arr[0]);
        System.out.println("Value = " +  arr[1]);
    }
}

Also, the -D should be before the main class or the jar file in the java command line. Example : java -DArguments=a=1,b=2,c=3,d=4,e=cow MainClass

You can define a jar artifact in the module settings (or project structure).

• Right click the module > Open module settings > Artifacts > + > JAR > from modules with dependencies.
• Set the main class.

Making a jar is then as easy as clicking "Build artifact..." from the Build menu. As a bonus, you can package all the dependencies into a single jar.

Limit the length of characters in a regular expression? ^[a-z]{6,15}$'

Limit length of characters or Numbers in a regular expression? ^[a-z | 0-9]{6,15}$'

DazWorrall's answer is spot on. Here's a variation that might be useful if your code is structured differently than the OP's:

num_rows_deleted = db.session.query(Model).delete()

Also, don't forget that the deletion won't take effect until you commit, as in this snippet:

try:
    num_rows_deleted = db.session.query(Model).delete()
    db.session.commit()
except:
    db.session.rollback()

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

Do this, it will work.

trim(replace(ntwk_slctor_key_txt, chr(0), ''))

I solved this by choosing 'SansSerif' or 'Serif' only and not 'Arial' or 'Times New Roman'.

Hi i am same problem and resolve this ways.

windows user and vs cant'create .bowerrc file.

in cmd go any folder

install any packages which is contains .bowerrc file forexample

bower install angular-local-storage

this plugin contains .bowerrc file. copy that and go to your project and paste this file.

and in visual studio - solution explorer - show all files and include project seen .bowerrc file

i resolve this ways :)

Here's a video that will show you, step-by-step, how to export data to Excel. It's a great solution for 'one-off' problems where you need to export to Excel:
Ad-Hoc Reporting

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

i faced the same issue under IIS 8.5. A working solution for me was changing the IIS to display detailled errors. See answer from sna2stha. But i think it is not a good idea to forward detailed error messages to browsers in production enviroments. I added/changed the existingResponse attribute in the httpErrors-Section, so the IIS not handled any extisting Asp.net Response:

<system.webServer>
   <httpErrors existingResponse="PassThrough" />
</system.webServer>

This works for me.

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

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

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

Example:

Entity class (for completeness):

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

Repository interface:

package myapp.domain.myentity;

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

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

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

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

}

Custom methods implementation bean:

package myapp.infrastructure.myentity;

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

    @PersistenceContext
    private EntityManager entityManager;

    @Autowired
    private MyEntityRepository myEntityRepository;

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

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

}

Usage:

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

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

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

The only possible drawbacks I identified are:

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

Then the last class attribute (class="current") goes in the hyper-link code of the link in the page that you want the active current link to correspond to.

Example: You want the link tab to stay active or highlighted when it's correspondent page is whats currently in view, go to that page itself and place the class="current" attribute by it's link's html code. Only in the page that corresponds to the link so that when ever that page is at view, the tab will stay highlighted or stand out different from the rest of the tabs.

For the Home page, go to the home page and place the class in it. example: <a href="http://Yourhomepage-url.com/" class="current" target="_parent">

For the About page, go to the about page and place the class in it. example: <a href="http://Yourhomepage-url.com/youraboutpage-url.php_or_.html" class="current" target="_parent">

For the Contact page, go to the contact page and place the class in it. example: <a href="http://Yourhomepage-url.com/youraboutpage-url.php_or_.html" class="current" target="_parent">

etc ......

Notice the example Table above;- Lets assume this was the Home page, so on this page, only the Home url link section has the class="current"

Sorry for any meaning-less error, am not a prof. but this worked for me and displays fine in almost all the browsers tested, including ipad, and smart phones. Hope this will help some-one out here because is very frustrating to want to and not able to. I had tried so had to get to this, and so far it's good for me.

git rebase origin means "rebase from the tracking branch of origin", while git rebase origin/master means "rebase from the branch master of origin"

You must have a tracking branch in ~/Desktop/test, which means that git rebase origin knows which branch of origin to rebase with. If no tracking branch exists (in the case of ~/Desktop/fallstudie), git doesn't know which branch of origin it must take, and fails.

To fix this, you can make the branch track origin/master with:

git branch --set-upstream-to=origin/master 

Or, if master isn't the currently checked-out branch:

git branch --set-upstream-to=origin/master master

To invoke the procedure from the SQLPlus command line, try one of these:

CALL test_sp_1();
EXEC test_sp_1

A solution using mutate_all from dplyr in case you want to add that to your dplyr pipeline:

library(dplyr)
df %>%
  mutate_all(funs(ifelse(is.na(.), 0, .)))

Result:

   A B C
1  0 0 0
2  1 0 0
3  2 0 2
4  3 0 5
5  0 0 2
6  0 0 1
7  1 0 1
8  2 0 5
9  3 0 2
10 0 0 4
11 0 0 3
12 1 0 5
13 2 0 5
14 3 0 0
15 0 0 1

If in any case you only want to replace the NA's in numeric columns, which I assume it might be the case in modeling, you can use mutate_if:

library(dplyr)
df %>%
  mutate_if(is.numeric, funs(ifelse(is.na(.), 0, .)))

or in base R:

replace(is.na(df), 0)

Result:

   A    B C
1  0    0 0
2  1 <NA> 0
3  2    0 2
4  3 <NA> 5
5  0    0 2
6  0 <NA> 1
7  1    0 1
8  2 <NA> 5
9  3    0 2
10 0 <NA> 4
11 0    0 3
12 1 <NA> 5
13 2    0 5
14 3 <NA> 0
15 0    0 1

Update

with dplyr 1.0.0, across is introduced:

library(dplyr)
# Replace `NA` for all columns
df %>%
  mutate(across(everything(), ~ ifelse(is.na(.), 0, .)))

# Replace `NA` for numeric columns
df %>%
  mutate(across(where(is.numeric), ~ ifelse(is.na(.), 0, .)))

Data:

set.seed(123)
df <- data.frame(A=rep(c(0:3, NA), 3), 
                 B=rep(c("0", NA), length.out = 15), 
                 C=sample(c(0:5, NA), 15, replace = TRUE))

It's as easy as:

delete object.keyname;

or

delete object["keyname"];

There is no jquery needed:

var matchedPosition = str.search(/[a-z]/i);
if(matchedPosition != -1) {
    alert('found');
}

"SELECT *
  INTO 
    @TempCustomer 
FROM 
    Customer
WHERE 
    CustomerId = @CustomerId"

Which means creating a new @tempCustomer tablevariable and inserting data FROM Customer. You had already declared it above so no need of again declaring. Better to go with

INSERT INTO @tempCustomer SELECT * FROM Customer

You could create a database for x conversations which contains all messages of these conversations. This would allow you to add a new Database (or server) each time x exceeds. X is the number conversations your infrastructure supports (depending on your hardware,...).

The problem is still, that there may be big conversations (with a lot of messages) on the same database. e.g. you have database A and database B an each stores e.g. 1000 conversations. It my be possible that there are far more "big" conversations on server A than on server B (since this is user created content). You could add a "master" database that contains a lookup, on which database/server the single conversations can be found (or you have a schema to assign a database from hash/modulo or something).

Maybe you can find real world architectures that deal with the same problems (you may not be the first one), and that have already been solved.

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)
2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'

Acutally, it gives several examples of compile commands used for pthreads codes are listed in the table below, if you continue reading the following tutorial:

https://computing.llnl.gov/tutorials/pthreads/#Compiling

Use $# to grab the number of arguments, if it is unequal to 2 there are not enough arguments provided:

if [ $# -ne 2 ]; then
   usage;
fi

Next, check if $1 equals -t, otherwise an unknown flag was used:

if [ "$1" != "-t" ]; then
  usage;
fi

Finally store $2 in FLAG:

FLAG=$2

Note: usage() is some function showing the syntax. For example:

function usage {
   cat << EOF
Usage: script.sh -t <application>

Performs some activity
EOF
   exit 1
}

Click settings and search for "Repositories", then select the local repo and click "Update". That's all. This action meets my need.

Using C++11 there is a nice version for a manually defined byte type:

enum class byte : std::uint8_t {};

That's at least what the GSL does.

Starting with C++17 (almost) this very version is defined in the standard as std::byte (thanks Neil Macintosh for both).

I had similar issues. I work on a Windows tool chain with a shared repository with Linux guys, and they happily create files with the same (except for case) names in a given folder.

The effect is that I can clone the repository and immediately have dozens of 'modified' files that, if I checked in, would create havoc.

I have Windows set to case sensitive and Git to not ignore case, but it still fails (in the Win32 API calls apparently).

If I gitignore the files then I have to remember to not track the .gitignore file.

But I found a good answer here:

http://archive.robwilkerson.org/2010/03/02/git-tip-ignore-changes-to-tracked-files/index.html

I'm hoping your problem has been solved by now. If not, try this... It looks like you have server=y for both your app and IDEA. IDEA should probably be server=n. Also, the (IDEA) client should have an address that includes both the host name and the port, e.g., address=127.0.0.1:9009.

I have a case where I am transforming a legacy DB2 z/os database timestamp (formatted as: "yyyy-MM-dd'T'HH:mm:ss.SSSZ") into a SqlServer 2016 datetime2 (formatted as: "yyyy-MM-dd HH:mm:ss.SSS) field that is handled by our Spring/Hibernate Entity Manager instance (in this case, the OldRevision Table). In the Class, I define the date as the java.util type, and write the setter and getter in the normal way. Then, When handling the data, the code I have handling the data related to this question looks like this:

OldRevision revision = new OldRevision();
String oldRevisionDateString= oldRevisionData.getString("originalRevisionDate", "");
Date oldDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
oldDateFormat.parse(oldRevisionDateString);
SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
Date finalFormattedDate= newDateFormat.parse(newDateFormat.format(oldDateFormat));
revision.setOriginalRevisionDate(finalFormattedDate);
em.persist(revision);

A simpler way to do the same case is:

SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
revision.setOriginalRevisionDate(
        newDateFormat.parse(newDateFormat.format(
                new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ")
                        .parse(rs.getString("originalRevisionDate", "")))));

var origParseFloat = parseFloat;
parseFloat = function(str) {
     alert("And I'm in your floats!");
     return origParseFloat(str);
}

It may be possible to make your Enum implement Serializable then you can pass it via the Intent, as there is a method for passing it as a serializable. The advice to use int instead of enum is bogus. Enums are used to make your code easier to read and easier to maintain. It would a large step backwards into the dark ages to not be able to use Enums.

Not quite, although generally you can usually use some workaround on one of the forms

• [^abc], which is character by character not a or b or c,
• or negative lookahead: a(?!b), which is a not followed by b
• or negative lookbehind: (?<!a)b, which is b not preceeded by a

This article have very good explanation and it solved my problem.

To get the ASCII code of a character, you can use the ord() function.

Here is an example code:

value = input("Your value here: ")
list=[ord(ch) for ch in value]
print(list)

Output:

Your value here: qwerty
[113, 119, 101, 114, 116, 121]

You can just change one attribute for you Cars car property from XmlArrayItem to XmlElment. That is, from

[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
    [XmlArrayItem(typeof(Car))]
    public Car[] Car { get; set; }
}

to

[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
    [XmlElement("Car")]
    public Car[] Car { get; set; }
}

In current releases of nmap you can use:

sudo nmap -sn 192.168.0.*

This will print the MAC addresses of all available hosts. Of course provide your own network, subnet and host id's.

Further explanation can be found here.

the refer link is like this:

exports = module.exports = function(){
    //....
}

the properties of exports or module.exports ,such as functions or variables , will be exposed outside

there is something you must pay more attention : don't override exports .

why ?

because exports just the reference of module.exports , you can add the properties onto the exports ,but if you override the exports , the reference link will be broken .

good example :

exports.name = 'william';

exports.getName = function(){
   console.log(this.name);
}

bad example :

exports = 'william';

exports = function(){
     //...
}

If you just want to exposed only one function or variable , like this:

// test.js
var name = 'william';

module.exports = function(){
    console.log(name);
}   

// index.js
var test = require('./test');
test();

this module only exposed one function and the property of name is private for the outside .

I have to add that bundles are used by activities to pass data to themselves in the future.

When the screen rotates, or when another activity is started, the method protected void onSaveInstanceState(Bundle outState) is invoked, and the activity is destroyed. Later, another instance of the activity is created, and public void onCreate(Bundle savedInstanceState) is called. When the first instance of activity is created, the bundle is null; and if the bundle is not null, the activity continues some business started by its predecessor.

Android automatically saves the text in text fields, but it does not save everything, and subtle bugs sometimes appear.

The most common anti-pattern, though, is assuming that onCreate() does just initialization. It is wrong, because it also must restore the state.

There is an option to disable this "re-create activity on rotation" behavior, but it will not prevent restart-related bugs, it will just make them more difficult to mention.

Note also that the only method whose call is guaranteed when the activity is going to be destroyed is onPause(). (See the activity life cycle graph in the docs.)

The jsqrcode library by Lazarsoft is now working perfectly using just HTML5, i.e. getUserMedia (WebRTC). You can find it on GitHub.

I also found a great fork which is much simplified. Just one file (plus jQuery) and one call of a method: see html5-qrcode on GitHub.

it clears stdin buffer before reading. From the man page:

For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.

Note: This is Linux-specific, using fflush() on input streams is undefined by the standard, however, most implementations behave the same as in Linux.

$(document).ready(function() {
       scope.$apply(function() {
                applyHeight();
            });
});

This also ensures that all the scripts have been loaded before the execution of the statements. If you dont need that you can use

$(window).load(function() {
       scope.$apply(function() {
                applyHeight();
            });
});

If you don't want to send the full modal structure you can replicate the old behaviour doing something like this:

// this is just an example, remember to adapt the selectors to your code!
$('.modal-link').click(function(e) {
    var modal = $('#modal'), modalBody = $('#modal .modal-body');

    modal
        .on('show.bs.modal', function () {
            modalBody.load(e.currentTarget.href)
        })
        .modal();
    e.preventDefault();
});

If we encapsulate that in a function we could use recursion and state clearly the purpose by naming the function properly (not sure if getAny is actually a good name):

def getAny(dic, keys, default=None):
    return (keys or default) and dic.get(keys[0], 
                                         getAny( dic, keys[1:], default=default))

or even better, without recursion and more clear:

def getAny(dic, keys, default=None):
    for k in keys: 
        if k in dic:
           return dic[k]
    return default

Then that could be used in a way similar to the dict.get method, like:

getAny(myDict, keySet)

and even have a default result in case of no keys found at all:

getAny(myDict, keySet, "not found")

Expanding on the definitions given, the most important thing you need to know as a web-developer is that NO STATE IS SAVED between postbacks. There are ways to retain state, such as the Session or Viewstate collections in ASP.NET, but as a rule of thumb write your programs where you can recreate your state on every postback.

This is probably the biggest difference between desktop and web-based application programming, and took me months to learn to the point where I was instinctively writing this way.

$sql = "select column_name from information_schema.columns where table_name = 'myTable'";

PHP function credits : http://www.sitepoint.com/forums/php-application-design-147/get-pdo-column-name-easy-way-559336.html

    function getColumnNames(){ 

    $sql = "select column_name from information_schema.columns where table_name = 'myTable'";
    #$sql = 'SHOW COLUMNS FROM ' . $this->table; 

    $stmt = $this->connection->prepare($sql); 

    try {     
        if($stmt->execute()){ 
            $raw_column_data = $stmt->fetchAll(PDO::FETCH_ASSOC); 

            foreach($raw_column_data as $outer_key => $array){ 
                foreach($array as $inner_key => $value){ 
                            if (!(int)$inner_key){ 
                                $this->column_names[] = $value; 
                            } 
                } 
            } 
            } 
            return $this->column_names; 
        } catch (Exception $e){ 
                return $e->getMessage(); //return exception 
        }         
    }  

Another good approach not mentioned in other posts is to use PropertyOverrideConfigurer in case you just want to override properties of some beans.

For example if you want to override the datasource for testing (i.e. use an in-memory database) in another xml config, you just need to use <context:property-override ..."/> in new config and a .properties file containing key-values taking the format beanName.property=newvalue overriding the main props.

application-mainConfig.xml:

<bean id="dataSource" 
    class="org.apache.commons.dbcp.BasicDataSource" 
    p:driverClassName="org.postgresql.Driver"
    p:url="jdbc:postgresql://localhost:5432/MyAppDB" 
    p:username="myusername" 
    p:password="mypassword"
    destroy-method="close" />

application-testConfig.xml:

<import resource="classpath:path/to/file/application-mainConfig.xml"/>

<!-- override bean props -->
<context:property-override location="classpath:path/to/file/beanOverride.properties"/>

beanOverride.properties:

dataSource.driverClassName=org.h2.Driver
dataSource.url=jdbc:h2:mem:MyTestDB

Indeed SET TEST_VARIABLE=value works for current process only, so SETX is required. A quick example for permanently storing an environment variable at user level.

1. In cmd, SETX TEST_VARIABLE etc. Not applied yet (echo %TEST_VARIABLE% shows %TEST_VARIABLE%,
2. Quick check: open cmd, echo %TEST_VARIABLE% shows etc.
3. GUI check: System Properties -> Advanced -> Environment variables -> User variables for -> you should see Varible TEST_VARIABLE with value etc.

You could use cursor up to delete a line, and erase text, or simply overwrite with the old text with new text.

int count = 1; 
System.out.print(String.format("\033[%dA",count)); // Move up
System.out.print("\033[2K"); // Erase line content

or clear screen

System.out.print(String.format("\033[2J"));

This is standard, but according to wikipedia the Windows console don't follow it.

Today March 6, 2013, Microsoft released SQL Server Data Tools – Business Intelligence for Visual Studio 2012 (SSDT BI) templates. With SSDT BI for Visual Studio 2012 you can develop and deploy SQL Server Business intelligence projects. Projects created in Visual Studio 2010 can be opened in Visual Studio 2012 and the other way around without upgrading or downgrading – it just works.

The download/install is named to ensure you get the SSDT templates that contain the Business Intelligence projects. The setup for these tools is now available from the web and can be downloaded in multiple languages right here: http://www.microsoft.com/download/details.aspx?id=36843

For people that are using PDO statements

$query = $db->prepare('show tables');
$query->execute();

while($rows = $query->fetch(PDO::FETCH_ASSOC)){
     var_dump($rows);
}

this happened again around last quarter of 2017 . greasemonkey firing too late . after domcontentloaded event already been fired.

what to do:

• i used @run-at document-start instead of document-end
• updated firefox to 57.

from : https://github.com/greasemonkey/greasemonkey/issues/2769

Even as a (private) script writer I'm confused why my script isn't working.

The most likely problem is that the 'DOMContentLoaded' event is fired before the script is run. Now before you come back and say @run-at document-start is set, that directive isn't fully supported at the moment. Due to the very asynchronous nature of WebExtensions there's little guarantee on when something will be executed. When FF59 rolls around we'll have #2663 which will help. It'll actually help a lot of things, debugging too.

From Microsoft:

These uses for DateTimeOffset values are much more common than those for DateTime values. As a result, DateTimeOffset should be considered the default date and time type for application development.

_{source: "Choosing Between DateTime, DateTimeOffset, TimeSpan, and TimeZoneInfo", MSDN}

We use DateTimeOffset for nearly everything as our application deals with particular points in time (e.g. when a record was created/updated). As a side note, we use DATETIMEOFFSET in SQL Server 2008 as well.

I see DateTime as being useful when you want to deal with dates only, times only, or deal with either in a generic sense. For example, if you have an alarm that you want to go off every day at 7 am, you could store that in a DateTime utilizing a DateTimeKind of Unspecified because you want it to go off at 7am regardless of DST. But if you want to represent the history of alarm occurrences, you would use DateTimeOffset.

Use caution when using a mix of DateTimeOffset and DateTime especially when assigning and comparing between the types. Also, only compare DateTime instances that are the same DateTimeKind because DateTime ignores timezone offset when comparing.

The -expandproperty does not work with more than 1 object. You can use this one :

Select-Object Name | ForEach-Object {$_.Name}

If there is more than one value then :

Select-Object Name, Country | ForEach-Object {$_.Name + " " + $Country}

you can also use the following:

s.concat("world")

Don't pass db models directly to your views. You're lucky enough to be using MVC, so encapsulate using view models.

Create a view model class like this:

public class EmployeeAddViewModel
{
    public Employee employee { get; set; }
    public Dictionary<int, string> staffTypes { get; set; }
    // really? a 1-to-many for genders
    public Dictionary<int, string> genderTypes { get; set; }

    public EmployeeAddViewModel() { }
    public EmployeeAddViewModel(int id)
    {
        employee = someEntityContext.Employees
            .Where(e => e.ID == id).SingleOrDefault();

        // instantiate your dictionaries

        foreach(var staffType in someEntityContext.StaffTypes)
        {
            staffTypes.Add(staffType.ID, staffType.Type);
        }

        // repeat similar loop for gender types
    }
}

Controller:

[HttpGet]
public ActionResult Add()
{
    return View(new EmployeeAddViewModel());
}

[HttpPost]
public ActionResult Add(EmployeeAddViewModel vm)
{
    if(ModelState.IsValid)
    {
        Employee.Add(vm.Employee);
        return View("Index"); // or wherever you go after successful add
    }

    return View(vm);
}

Then, finally in your view (which you can use Visual Studio to scaffold it first), change the inherited type to ShadowVenue.Models.EmployeeAddViewModel. Also, where the drop down lists go, use:

@Html.DropDownListFor(model => model.employee.staffTypeID,
    new SelectList(model.staffTypes, "ID", "Type"))

and similarly for the gender dropdown

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(model.genderTypes, "ID", "Gender"))

Update per comments

For gender, you could also do this if you can be without the genderTypes in the above suggested view model (though, on second thought, maybe I'd generate this server side in the view model as IEnumerable). So, in place of new SelectList... below, you would use your IEnumerable.

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(new SelectList()
    {
        new { ID = 1, Gender = "Male" },
        new { ID = 2, Gender = "Female" }
    }, "ID", "Gender"))

Finally, another option is a Lookup table. Basically, you keep key-value pairs associated with a Lookup type. One example of a type may be gender, while another may be State, etc. I like to structure mine like this:

ID | LookupType | LookupKey | LookupValue | LookupDescription | Active
1  | Gender     | 1         | Male        | male gender       | 1
2  | State      | 50        | Hawaii      | 50th state        | 1
3  | Gender     | 2         | Female      | female gender     | 1
4  | State      | 49        | Alaska      | 49th state        | 1
5  | OrderType  | 1         | Web         | online order      | 1

I like to use these tables when a set of data doesn't change very often, but still needs to be enumerated from time to time.

Hope this helps!

I have found this small library that encapsulates what you need.

npm install zip-a-folder

const zip-a-folder = require('zip-a-folder');
await zip-a-folder.zip('/path/to/the/folder', '/path/to/archive.zip');

https://www.npmjs.com/package/zip-a-folder

ah, the beauty of ternaries:

const now = new Date();
const expiry = now.getMonth() == 11 ? new Date(now.getFullYear()+1, 0 , 1) : new Date(now.getFullYear(), now.getMonth() + 1, 1);

just a simpler version of the solution provided by @paxdiablo and @Tom

To pull a remote branch locally, I do the following:

git checkout -b branchname // creates a local branch with the same name and checks out on it

git pull origin branchname // pulls the remote one onto your local one

The only time I did this and it didn't work, I deleted the repo, cloned it again and repeated the above 2 steps; it worked.

      $imgReload.data('self', $self);
            $imgReload.click(function (e) {
                var $p = $(this).data('self');
                $p._reloadTable();
            });

Set javaScript object to onclick element:

 $imgReload.data('self', $self);

get Object from "this" element:

 var $p = $(this).data('self');

In my case, none of the above worked, however, replacing 5.2.3.0 with 4.0.0.0 did solve the problem.

in my .net core 3.1 applications I am getting two problem where inner cause was timeout exception. 1, one is i am getting aggregate exception and in it's inner exception was timeout exception 2, other case was Task canceled exception

My solution is

catch (Exception ex)
            {
                if (ex.InnerException is TimeoutException)
                {
                    ex = ex.InnerException;
                }
                else if (ex is TaskCanceledException)
                {
                    if ((ex as TaskCanceledException).CancellationToken == null || (ex as TaskCanceledException).CancellationToken.IsCancellationRequested == false)
                    {
                        ex = new TimeoutException("Timeout occurred");
                    }
                }                
                Logger.Fatal(string.Format("Exception at calling {0} :{1}", url, ex.Message), ex);
            }

If you use io.js, it has support for multi-line strings as they are in ECMAScript 6.

var a =
`this is
a multi-line
string`;

See "New String Methods" at http://davidwalsh.name/es6-io for details and "template strings" at http://kangax.github.io/compat-table/es6/ for tracking compatibility.

In Insert mode 
<C-A>   - Increments the number under cursor 
<C-X>   - Decrements the number under cursor

It will be very useful if we want to generate sequential numbers in vim
Lets say if we want to insert lines 1-10 with numbers from 1 to 10 [like "1" on 1st line,"2" on 2nd line..]
insert "0" on the first line and copy the line and past 9 times So that all lines will show "0".

Run the following Ex command

:g/^/exe "norm " . line(".") . "\<C-A>"

Go to the script and click "Raw"

Then copy the link and download it with the aria2c link.

Eg: aria2c https://raw.githubusercontent.com/kodamail/gscript/master/color.gsf

Trick: the file I wanted to download is, https://github.com/kodamail/gscript*/blob*/master/color.gsf

just modify the link into https://raw.githubusercontent.com/kodamail/gscript/master/color.gsf

Remove the italic texts and add bold texts in the same format, it will give you the right link.

which can be used with aria2c,wget or with curl, I used aria2c here.

The extension below will allow you to load a Storyboard and it's associated UIViewController. Example: If you have a UIViewController named ModalAlertViewController and a storyboard named "ModalAlert" e.g.

let vc: ModalAlertViewController = UIViewController.loadStoryboard("ModalAlert")

Will load both the Storyboard and UIViewController and vc will be of type ModalAlertViewController. Note Assumes that the storyboard's Storyboard ID has the same name as the storyboard and that the storyboard has been marked as Is Initial View Controller.

extension UIViewController {
    /// Loads a `UIViewController` of type `T` with storyboard. Assumes that the storyboards Storyboard ID has the same name as the storyboard and that the storyboard has been marked as Is Initial View Controller.
    /// - Parameter storyboardName: Name of the storyboard without .xib/nib suffix.
    static func loadStoryboard<T: UIViewController>(_ storyboardName: String) -> T? {
        let storyboard = UIStoryboard(name: storyboardName, bundle: nil)
        if let vc = storyboard.instantiateViewController(withIdentifier: storyboardName) as? T {
            vc.loadViewIfNeeded() // ensures vc.view is loaded before returning
            return vc
        }
        return nil
    }
}

This is an alternative solution, but one could argue it doesn't add enough value to make it worth it:

import com.google.common.collect.Iterables;
...
Iterator<String> iter = Iterables.cycle(list).iterator();
if(iter.hasNext()) {
    str = iter.next();
}

Calling hasNext() will reset the iterator cursor to the beginning if it's a the end.

It all depends on what you are trying to achieve with "saving locally". Do you want to allow the user to download the file? then <a download> is the way to go. Do you want to save it locally, so you can restore your application state? Then you might want to look into the various options of WebStorage. Specifically localStorage or IndexedDB. The FilesystemAPI allows you to create local virtual file systems you can store arbitrary data in.

This is a better approach without using any String function.

public static String ReverseCases(String str) {
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < str.length(); i++) {
      char temp;
      if (str.charAt(i) >= 'a' && str.charAt(i) <= 'z') {
        temp = (char)(str.charAt(i) - 32);
      }
      else if (str.charAt(i) >= 'A' && str.charAt(i) <= 'Z'){
        temp = (char)(str.charAt(i) + 32);
      }
      else {
        temp = str.charAt(i);
      }

      sb.append(temp);
    }
    return sb.toString();
  }

I had (have) a similar problem in a Java application. I wrote a JDBC driver wrapper around the Oracle driver so all output is sent to a log file.

Use

$route.reload();

remember to inject $route to your controller.

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

I knew that SQL was bad at string manipulation, but I didn't think it would be this difficult. Here's a simple function to strip out all the numbers from a string. There would be better ways to do this, but this is a start.

My challenge to readers: Can you make this more efficient? What about using recursion?

If using ES6, you could use a for loop to achieve this:

for (let i = 1; i < 10; i++) {
  setTimeout(function timer() {
    console.log("hello world");
  }, i * 3000);
}

It declares i for each iteration, meaning the timeout is what it was before + 1000. This way, what is passed to setTimeout is exactly what we want.

This works fine on LG Android phones. It prevents ENTER and other special characters to be interpreted as normal character. Next or Done button appears automatically and ENTER works as expected.

edit.setInputType(InputType.TYPE_CLASS_TEXT);

I never tried using formArray, I have always worked with FormGroup, and you can remove all controls using:

Object.keys(this.formGroup.controls).forEach(key => {
          this.formGroup.removeControl(key);
        });

being formGroup an instance of FormGroup.

Try this:

<input type="button" value="Reload" onClick="history.go(0)">

Use the noinline attribute:

int func(int arg) __attribute__((noinline))
{
}

You should probably use it both when you declare the function for external use and when you write the function.

One option is to use a ranking variable, such as the following:

SELECT    first_name,
          age,
          gender,
          @curRank := @curRank + 1 AS rank
FROM      person p, (SELECT @curRank := 0) r
ORDER BY  age;

The (SELECT @curRank := 0) part allows the variable initialization without requiring a separate SET command.

Test case:

CREATE TABLE person (id int, first_name varchar(20), age int, gender char(1));

INSERT INTO person VALUES (1, 'Bob', 25, 'M');
INSERT INTO person VALUES (2, 'Jane', 20, 'F');
INSERT INTO person VALUES (3, 'Jack', 30, 'M');
INSERT INTO person VALUES (4, 'Bill', 32, 'M');
INSERT INTO person VALUES (5, 'Nick', 22, 'M');
INSERT INTO person VALUES (6, 'Kathy', 18, 'F');
INSERT INTO person VALUES (7, 'Steve', 36, 'M');
INSERT INTO person VALUES (8, 'Anne', 25, 'F');

Result:

+------------+------+--------+------+
| first_name | age  | gender | rank |
+------------+------+--------+------+
| Kathy      |   18 | F      |    1 |
| Jane       |   20 | F      |    2 |

To enable Event Tracing for Windows for your website/application

1. Go to Logging and ensure either ETW event only or Both log file and ETW event ...is selected.

2. Enable the desired Recycle logs in the Advanced Settings for the Application Pool:

3. Go to the default Custom View: WebServer filters IIS logs:

Custom Views > ServerRoles > Web Server

4. ... or System logs:

Windows Logs > System

There are a number of ways that you could do this, but the fastest might be to use IndexOf to find the index position of the letter you want to replace and then substring out the text before and after what you want to replace.

when you select run configuration, there is a JRE tap up next the main tap, select "Workspace default JRE(JDK1.7)".

Be sure to use the jdk in Prefs->Java->Installed JREs ->Execution Environment

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

Read the paper: Porikli, Fatih, Oncel Tuzel, and Peter Meer. “Covariance Tracking Using Model Update Based on Means on Riemannian Manifolds”. (2006) IEEE Computer Vision and Pattern Recognition.

I was successfully able to detect overlapping regions in images captured from adjacent webcams using the technique presented in this paper. My covariance matrix was composed of Sobel, canny and SUSAN aspect/edge detection outputs, as well as the original greyscale pixels.

The ODP.Net provider from oracle uses bind by position as default. To change the behavior to bind by name. Set property BindByName to true. Than you can dismiss the double definition of parameters.

using(OracleCommand cmd = con.CreateCommand()) {
    ...
    cmd.BindByName = true;
    ...
}

If you want all the CSS thats on your webpage in your IFrame, try this:

var headClone, iFrameHead;

// Create a clone of the web-page head
headClone = $('head').clone();

// Find the head of the the iFrame we are looking for
iFrameHead = $('#iframe').contents().find('head');

// Replace 'iFrameHead with your Web page 'head'
iFrameHead.replaceWith(headClone);

// You should now have all the Web page CSS in the Iframe

Good Luck.

There should be a line in your postgresql.conf file that says:

port = 1486

Change that.

The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/

On Windows it is C:\Program Files\PostgreSQL\9.3\data

Don't forget to sudo service postgresql restart for changes to take effect.

Add to the main __init__.py in YourClassParentDir, e.g.:

from .YourClass import YourClass

Then, you will have an instance of your class ready when you import it into another script:

from YourClassParentDir import YourClass

The maximum length of the table and column name is 128 bytes or 128 characters. This limit is for using sybase database users. I verified this answer thoroughly, so that I have posted this answer confidently.

Try this:
add in html following

<input type="text" id="datepicker"/>

Add in js file

$(function() {
   $( "#datepicker" ).datepicker({dateFormat: 'yy',  changeYear: true,  changeMonth: false});
});

Add in css

.ui-datepicker-calendar {
       display: none;
    }
    .ui-datepicker-month {
       display: none;
    }
    .ui-datepicker-prev{
       display: none;

Working Demo

The issue pointed in the comment is valid, so here is a different revision that's immune to that:

function show_alert() {
  if(!confirm("Do you really want to do this?")) {
    return false;
  }
  this.form.submit();
}

I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.

If provider & "" <> "" Then 
    url = url & "&provider=" & provider 
End if

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

I am working on a MVC5/Web API project and needed to be able to get authorization for the Web Api methods. When my index view is first loaded I make a call to the 'token' Web API method which I believe is created automatically.

The client side code (CoffeeScript) to get the token is:

getAuthenticationToken = (username, password) ->
    dataToSend = "username=" + username + "&password=" + password
    dataToSend += "&grant_type=password"
    $.post("/token", dataToSend).success saveAccessToken

If successful the following is called, which saves the authentication token locally:

saveAccessToken = (response) ->
    window.authenticationToken = response.access_token

Then if I need to make an Ajax call to a Web API method that has the [Authorize] tag I simply add the following header to my Ajax call:

{ "Authorization": "Bearer " + window.authenticationToken }

You can instanciate LocalReport

You need to either transpile/compile that JSX code to javascript or use the in-browser transformator

Look at http://facebook.github.io/react/docs/getting-started.html and take note of the <script> tags, you need those included for JSX to work in the browser.

If #box is empty, nothing, but if it's not these do very different things. The former will add a div as the last child node of #box. The latter completely replaces the contents of #box with a single empty div, text and all.

tigeravatar and Jean-François Corbett suggested to use this formula to generate the string right of the last occurrence of the "\" character

=TRIM(RIGHT(SUBSTITUTE(A1,"\",REPT(" ",LEN(A1))),LEN(A1)))

If the character used as separator is space, " ", then the formula has to be changed to:

=SUBSTITUTE(RIGHT(SUBSTITUTE(A1," ",REPT("{",LEN(A1))),LEN(A1)),"{","")

No need to mention, the "{" character can be replaced with any character that would not "normally" occur in the text to process.

You are searching/reading the file "fiel.txt" in the execution directory (where the class are stored, i think).

If you whish to read the file in a given directory, you have to says so :

File file = new File(System.getProperty("user.dir")+"/"+"file.txt");

You could also give the directory with a relative path, eg "./images/photo.gif) for a subdirecory for example.

Note that there is also a property for the separator (hard-coded to "/" in my exemple)

The standard mathematical way for positive integers is to use the uniqueness of prime factorization.

f( x, y ) -> 2^x * 3^y

The downside is that the image tends to span quite a large range of integers so when it comes to expressing the mapping in a computer algorithm you may have issues with choosing an appropriate type for the result.

You could modify this to deal with negative x and y by encoding a flags with powers of 5 and 7 terms.

e.g.

f( x, y ) -> 2^|x| * 3^|y| * 5^(x<0) * 7^(y<0)

In SQL you can not have a variable array.
However, the best alternative solution is to use a temporary table.

You can always do something shell-scripty like:

#!/usr/bin/node

var header = "Content-type: text/plain\n";
var hi = "Hello World from nodetest!";
console.log(header);
console.log(hi);

exit;

Another one-liner, without counting hyper-threaded cores:

lscpu | awk -F ":" '/Core/ { c=$2; }; /Socket/ { print c*$2 }' 

The include path is set against the server configuration (PHP.ini) but the include path you specify is relative to that path so in your case the include path is (actual path in windows):

C:\xampp\php\PEAR\initcontrols\header_myworks.php

providing the path you pasted in the subject is correct. Make sure your file is located there.

For more info you can get and set the include path programmatically.

1. Open MySQL Workbench. In the home screen click 'Create EER Model From Existing Database'. We are doing this for the case that we have already made the data base and now we want to make an ER diagram of that database.

2. Then you will see the 'Reverse Engineer Database' dialouge. Here if you are asked for the password, provided the admin password. Do not get confused here with the windows password. Here you need to provide the MySQL admin password. Then click on Next.

3. In the next dialouge box, you'll see that the connection to DBMS is started and schema is revrieved from Database. Go next.

4. Now Select the Schema you created earlier. It is the table you want to create the ER diagram of.

5. Click Next and go to Select Objects menu. Here you can click on 'Show Filter' to use the selected Table Objects in the diagram. You can both add and remove tables here.Then click on Execute.

6.When you go Next and Finish, the required ER diagram is on the screen.

You can put your column name in bracket like:

Select  [from] from < ur_tablename>

Or

Put in a temprary table then use as you like.
Example:

Declare @temp_table table(temp_from varchar(max))

Insert into @temp_table
Select * from your_tablename

Here I just assume that your_tablename contains only one column (i.e. from).

Please check this:

import webbrowser

webbrowser.get(chrome_path).open('http://docs.python.org/')

You probably need to use reflection to get the types of them to check. To get the type of the List: Get generic type of java.util.List

Basically what you do is correct. Looking at redmine docs you linked to, it seems that suffix after the dot in the url denotes type of posted data (.json for JSON, .xml for XML), which agrees with the response you get - Processing by AttachmentsController#upload as XML. I guess maybe there's a bug in docs and to post binary data you should try using http://redmine/uploads url instead of http://redmine/uploads.xml.

Btw, I highly recommend very good and very popular Requests library for http in Python. It's much better than what's in the standard lib (urllib2). It supports authentication as well but I skipped it for brevity here.

import requests
with open('./x.png', 'rb') as f:
    data = f.read()
res = requests.post(url='http://httpbin.org/post',
                    data=data,
                    headers={'Content-Type': 'application/octet-stream'})

# let's check if what we sent is what we intended to send...
import json
import base64

assert base64.b64decode(res.json()['data'][len('data:application/octet-stream;base64,'):]) == data

UPDATE

To find out why this works with Requests but not with urllib2 we have to examine the difference in what's being sent. To see this I'm sending traffic to http proxy (Fiddler) running on port 8888:

Using Requests

import requests

data = 'test data'
res = requests.post(url='http://localhost:8888',
                    data=data,
                    headers={'Content-Type': 'application/octet-stream'})

we see

POST http://localhost:8888/ HTTP/1.1
Host: localhost:8888
Content-Length: 9
Content-Type: application/octet-stream
Accept-Encoding: gzip, deflate, compress
Accept: */*
User-Agent: python-requests/1.0.4 CPython/2.7.3 Windows/Vista

test data

and using urllib2

import urllib2

data = 'test data'    
req = urllib2.Request('http://localhost:8888', data)
req.add_header('Content-Length', '%d' % len(data))
req.add_header('Content-Type', 'application/octet-stream')
res = urllib2.urlopen(req)

we get

POST http://localhost:8888/ HTTP/1.1
Accept-Encoding: identity
Content-Length: 9
Host: localhost:8888
Content-Type: application/octet-stream
Connection: close
User-Agent: Python-urllib/2.7

test data

I don't see any differences which would warrant different behavior you observe. Having said that it's not uncommon for http servers to inspect User-Agent header and vary behavior based on its value. Try to change headers sent by Requests one by one making them the same as those being sent by urllib2 and see when it stops working.

easiest by far is to return nil, or "" in func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? for a section where you do not wish to display header.

This will find the second occurrence of substring in string.

def find_2nd(string, substring):
   return string.find(substring, string.find(substring) + 1)

Edit: I haven't thought much about the performance, but a quick recursion can help with finding the nth occurrence:

def find_nth(string, substring, n):
   if (n == 1):
       return string.find(substring)
   else:
       return string.find(substring, find_nth(string, substring, n - 1) + 1)

"Both" has been stated above, and is the obvious answer...but IMO, white box testing goes far beyond developer unit testing (althoughI suppose it could depend on where you draw the line between white and black). For example, code coverage analysis is a common white box approach - i.e. run some scenarios or tests, and examine the results looking for holes in testing. Even if unit tests have 100% cc, measuring cc on common user scenarios can reveal code that may potentially need even more testing.

Another place where white box testing helps is examining data types, constants and other information to look for boundaries, special values, etc. For example, if an application has an input that takes a numeric input, a bb only approach could require the tester to "guess" at what values would be good for testing, whereas a wb approach may reveal that all values between 1-256 are treated one way, while larger values are treated another way...and perhaps the number 42 has yet another code path.

So, to answer the original question - both bb and wb are essential for good testing.

You can retrieve all the keys of the $_POST array using array_keys(), then construct an email messages with the values of those keys.

var_dump($_POST) will also dump information about all of the information in $_POST for you.

I find the below RE working fine for Date in the following format;

1. 14-11-2017
2. 14.11.2017
3. 14|11|2017

It can accept year from 2000-2099

Please do not forget to add $ at the end,if not it accept 14-11-201 or 20177

date="13-11-2017"

x=re.search("^([1-9] |1[0-9]| 2[0-9]|3[0-1])(.|-)([1-9] |1[0-2])(.|-|)20[0-9][0-9]$",date)

x.group()

output = '13-11-2017'

Why does it give me that error?

Because your first parameter you pass to the loop function is None but your function is expecting an callable object, which None object isn't.

Therefore you have to pass the callable-object which is in your case the hi function object.

def hi():     
  print 'hi'

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)

echo -e $lines | while read line 
    ...
done

The while loop is executed in a subshell. So any changes you do to the variable will not be available once the subshell exits.

Instead you can use a here string to re-write the while loop to be in the main shell process; only echo -e $lines will run in a subshell:

while read line
do
    if [[ "$line" == "second line" ]]
    then
        foo=2
        echo "Variable \$foo updated to $foo inside if inside while loop"
    fi
    echo "Value of \$foo in while loop body: $foo"
done <<< "$(echo -e "$lines")"

You can get rid of the rather ugly echo in the here-string above by expanding the backslash sequences immediately when assigning lines. The $'...' form of quoting can be used there:

lines=$'first line\nsecond line\nthird line'
while read line; do
    ...
done <<< "$lines"

Done after lots of R&D:

Ok, sorry for my previous answer, I had never seen that Overview screen before.

Here is how I did it:

1. Right click on my tomcat server in "Servers" view, select "Properties…"
2. In the "General" panel, click on the "Switch Location" button
3. The "Location: [workspace metadata]" bit should have been replaced by something else.
4. Open (or close and reopen) the Overview screen for the server.

You can try below code to solve your problem:

By default, first option select: jQuery('.select').find('option')[0].selected=true;

Thanks, Ketan T

The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:

Working Demo of select-ng-files Directive that Works with ng-model¹

angular.module("app",[]);

angular.module("app").directive("selectNgFiles", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" select-ng-files ng-model="fileList" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileList">
      {{file.name}}
    </div>
  </body>

$http.post from a FileList

$scope.upload = function(url, fileList) {
    var config = { headers: { 'Content-Type': undefined },
                   transformResponse: angular.identity
                 };
    var promises = fileList.map(function(file) {
        return $http.post(url, file, config);
    });
    return $q.all(promises);
};

When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.

With the advent of Django 1.7, there is now a new update_or_create QuerySet method, which should do exactly what you want. Just be careful of potential race conditions if uniqueness is not enforced at the database level.

Example from the documentation:

obj, created = Person.objects.update_or_create(
    first_name='John', last_name='Lennon',
    defaults={'first_name': 'Bob'},
)

The update_or_create method tries to fetch an object from database based on the given kwargs. If a match is found, it updates the fields passed in the defaults dictionary.

Pre-Django 1.7:

Change the model field values as appropriate, then call .save() to persist the changes:

try:
    obj = Model.objects.get(field=value)
    obj.field = new_value
    obj.save()
except Model.DoesNotExist:
    obj = Model.objects.create(field=new_value)
# do something else with obj if need be

In proto3, all fields are "optional" (in that it is not an error if the sender fails to set them). But, fields are no longer "nullable", in that there's no way to tell the difference between a field being explicitly set to its default value vs. not having been set at all.

If you need a "null" state (and there is no out-of-range value that you can use for this) then you will instead need to encode this as a separate field. For instance, you could do:

message Foo {
  bool has_baz = 1;  // always set this to "true" when using baz
  int32 baz = 2;
}

Alternatively, you could use oneof:

message Foo {
  oneof baz {
    bool baz_null = 1;  // always set this to "true" when null
    int32 baz_value = 2;
  }
}

The oneof version is more explicit and more efficient on the wire but requires understanding how oneof values work.

Finally, another perfectly reasonable option is to stick with proto2. Proto2 is not deprecated, and in fact many projects (including inside Google) very much depend on proto2 features which are removed in proto3, hence they will likely never switch. So, it's safe to keep using it for the foreseeable future.

This might sound like a really basic "DUH" answer, but make sure that the column you're using to Lookup from on the merging file is actually full of unique values!

I noticed earlier today that PowerQuery won't throw you an error (like in PowerPivot) and will happily allow you to run a Many-Many merge. This will result in multiple rows being produced for each record that matches with a non-unique value.

A simple solution to get a transparent background in a windows form is to overwrite the OnPaintBackground method like this:

protected override void OnPaintBackground(PaintEventArgs e)
{
    //empty implementation
}

(Notice that the base.OnpaintBackground(e) is removed from the function)

Here is what I use.

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

POSIX SED:

'${/^$/d}'

$ - match last line


{ COMMANDS } - A group of commands may be enclosed between { and } characters. This is particularly useful when you want a group of commands to be triggered by a single address (or address-range) match.

You start recording by q<letter> and you can end it by typing q again.

Recording is a really useful feature of Vim.

It records everything you type. You can then replay it simply by typing @<letter>. Record search, movement, replacement...

One of the best feature of Vim IMHO.

Not sure about your specific scenario, but you have three options:

1.) use Dictionary<..,..>
2.) create a wrapper class around your values and then you can use List
3.) use Tuple

You can coalesce your NULLs in the ORDER BY statement:

select * from tablename
where <conditions>
order by
    coalesce(position, 0) ASC, 
    id DESC

If you want the NULLs to sort on the bottom, try coalesce(position, 100000). (Make the second number bigger than all of the other position's in the db.)

Get all views of a view plus its children recursively in Kotlin:

private fun View.getAllViews(): List<View> {
    if (this !is ViewGroup || childCount == 0) return listOf(this)

    return children
            .toList()
            .flatMap { it.getAllViews() }
            .plus(this as View)
}

The problem in your code is xml.LoadXml(filePath);

LoadXml method take parameter as xml data not the xml file path

Try this code

   string xmlFile = File.ReadAllText(@"D:\Work_Time_Calculator\10-07-2013.xml");
                XmlDocument xmldoc = new XmlDocument();
                xmldoc.LoadXml(xmlFile);
                XmlNodeList nodeList = xmldoc.GetElementsByTagName("Short_Fall");
                string Short_Fall=string.Empty;
                foreach (XmlNode node in nodeList)
                {
                    Short_Fall = node.InnerText;
                }

Edit

Seeing the last edit of your question i found the solution,

Just replace the below 2 lines

XmlNode node = xml.SelectSingleNode("/Data[@*]/Short_Fall");
string id = node["Short_Fall"].InnerText; // Exception occurs here ("Object reference not set to an instance of an object.")

with

string id = xml.SelectSingleNode("Data/Short_Fall").InnerText;

It should solve your problem or you can use the solution i provided earlier.

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

To change into another directory use WORKDIR. All the RUN, CMD and ENTRYPOINT commands after WORKDIR will be executed from that directory.

RUN git clone XYZ 
WORKDIR "/XYZ"
RUN make

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

An often-used metaphor to describe Traits is Traits are interfaces with implementation.

This is a good way of thinking about it in most circumstances, but there are a number of subtle differences between the two.

For a start, the instanceof operator will not work with traits (ie, a trait is not a real object), therefore you can't use that to see if a class has a certain trait (or to see if two otherwise unrelated classes share a trait). That's what they mean by it being a construct for horizontal code re-use.

There are functions now in PHP that will let you get a list of all the traits a class uses, but trait-inheritance means you'll need to do recursive checks to reliably check if a class at some point has a specific trait (there's example code on the PHP doco pages). But yeah, it's certainly not as simple and clean as instanceof is, and IMHO it's a feature that would make PHP better.

Also, abstract classes are still classes, so they don't solve multiple-inheritance related code re-use problems. Remember you can only extend one class (real or abstract) but implement multiple interfaces.

I've found traits and interfaces are really good to use hand in hand to create pseudo multiple inheritance. Eg:

class SlidingDoor extends Door implements IKeyed  
{  
    use KeyedTrait;  
    [...] // Generally not a lot else goes here since it's all in the trait  
}

Doing this means you can use instanceof to determine if the particular Door object is Keyed or not, you know you'll get a consistent set of methods, etc, and all the code is in one place across all the classes that use the KeyedTrait.

Try escaping the slash: someString.replace(/\//g, "-");

By the way - / is a (forward-)slash; \ is a backslash.

you'd better off modifying server roles, which was designed for security privileges. add sysadmin server role to your user. for better security you may have your custom server roles. but this approach will give you what you want for now.

1. Object Explorer -> Server -> Security -> Logins
2. Right click on your desired user
3. Go to Server Roles on left hand side
4. Make sure sysadmin is checked
5. Hit OK and restart your SQL server

Good luck

If you just want to check the value is in Range, use this:

   MIN_VALUE = 1;
   MAX_VALUE = 100;
   $customValue = min(MAX_VALUE,max(MIN_VALUE,$customValue)));

The artifactId for all the dependencies that failed to download are incorrect - for some reason they are prefixed with com.springsource. Cut/paste issue?

You can try replacing them as follows.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>jta</artifactId>
    <version>1.1.0</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.5.6</version>
</dependency>

You may also want to add the maven central repository for these artifacts in case they are not available in the specified repositories.

<repository>
    <id>maven2</id>
    <url>http://repo1.maven.org/maven2</url>
</repository>

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

If you can change this line:

host    all        all         192.168.0.1/32        md5

With this:

host    all        all         all                   md5

You can see if this solves the problem.

But another consideration is your postgresql port(5432) is very open to password attacks with hackers (maybe they can brute force the password). You can change your postgresql port 5432 to '33333' or another value, so they can't know this configuration.

If supported by your browser, you may use CSS3 :read-only selector:

input[type="text"]:read-only {
    cursor: normal;
    background-color: #f8f8f8;
    color: #999;
}

In Windows 10, similar steps can be followed in other versions of windows.

Right Click on "My Computer" select Properties, Goto Advanced System Settings -> Advanced -> Select "Environment Variables.." .

Find "Path" select it and choose edit option -> Click on New and add "C:\MinGW\bin" (or the location of gcc.exe, if you have installed at some other location) -> Save and restart command prompt. Gcc should work.

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

Swift 3:

let escapedString = originalString.addingPercentEncoding(withAllowedCharacters:NSCharacterSet.urlQueryAllowed)

Try to use this free way to this, https://freenetexcel.codeplex.com

 Workbook workbook = new Workbook();

 workbook.LoadFromFile(@"..\..\parts.xls",ExcelVersion.Version97to2003);
 //Initialize worksheet
 Worksheet sheet = workbook.Worksheets[0];

 DataTable dataTable = sheet.ExportDataTable();

Basically, O(1) means its computation time is constant, while O(n) means it will depend lineally on the size of input - i.e. looping through an array has O(n) - just looping -, because it depends on the number of items, while calculating the maximum between to ordinary numbers has O(1).

[UPDATED] For Xcode 10+ & Swift 4.2+

This is the preferred method for iOS 7 and higher

In your application's Info.plist, set View controller-based status bar appearance to YES.

Override preferredStatusBarStyle (Apple docs) in each of your view controllers. For example:

override var preferredStatusBarStyle: UIStatusBarStyle {     
      return .lightContent
}

If you have preferredStatusBarStyle returning a different preferred status bar style based on something that changes inside of your view controller (for example, whether the scroll position or whether a displayed image is dark), then you will want to call setNeedsStatusBarAppearanceUpdate() when that state changes.

iOS before version 7, deprecated method

Apple has deprecated this, so it will be removed in the future. Use the above method so that you don't have to rewrite it when the next iOS version is released.

If your application will support In your application's Info.plist, set View controller-based status bar appearance to NO.

In appDelegate.swift, the didFinishLaunchingWithOptions function, add:

UIApplication.shared.statusBarStyle = .lightContent

For Navigation Controller

If you use a navigation controller and you want the preferred status bar style of each view controller to be used and set View controller-based status bar appearance to YES in your application's info.plist

extension UINavigationController {
   open override var preferredStatusBarStyle: UIStatusBarStyle {
      return topViewController?.preferredStatusBarStyle ?? .default
   }
}

The easiest way is to use sshpass. This is available in Ubuntu/Debian repositories and you don't have to deal with integrating expect with Bash.

An example:

sshpass -p<password> ssh <arguments>
sshpass -ptest1324 ssh [email protected] ls -l /tmp

The above command can be easily integrated with a Bash script.

Note: Please read the Security Considerations section in man sshpass for a full understanding of the security implications.

ToggleButton inherits from TextView so you can set drawables to be displayed at the 4 borders of the text. You can use that to display the icon you want on top of the text and hide the actual text

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableTop="@android:drawable/ic_menu_info_details"
    android:gravity="center"
    android:textOff=""
    android:textOn=""
    android:textSize="0dp" />

The result compared to regular ToggleButton looks like

The seconds option is to use an ImageSpan to actually replace the text with an image. Looks slightly better since the icon is at the correct position but can't be done with layout xml directly.

You create a plain ToggleButton

<ToggleButton
    android:id="@+id/toggleButton3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="false" />

Then set the "text" programmatially

ToggleButton button = (ToggleButton) findViewById(R.id.toggleButton3);
ImageSpan imageSpan = new ImageSpan(this, android.R.drawable.ic_menu_info_details);
SpannableString content = new SpannableString("X");
content.setSpan(imageSpan, 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(content);
button.setTextOn(content);
button.setTextOff(content);

The result here in the middle - icon is placed slightly lower since it takes the place of the text.

Is this what you are looking for?

Option Explicit

Public Sub addDataToTable(ByVal strTableName As String, ByVal strData As String, ByVal col As Integer)
    Dim lLastRow As Long
    Dim iHeader As Integer

    With ActiveSheet.ListObjects(strTableName)
        'find the last row of the list
        lLastRow = ActiveSheet.ListObjects(strTableName).ListRows.Count
        'shift from an extra row if list has header
        If .Sort.Header = xlYes Then
            iHeader = 1
        Else
            iHeader = 0
        End If
    End With
    'add the data a row after the end of the list
    ActiveSheet.Cells(lLastRow + 1 + iHeader, col).Value = strData
End Sub

It handles both cases whether you have header or not.

You have to escape the backslash, so try this:

str = "Hello\\nWorld";

Here are more escaped characters in Javascript.

This does not sound like a good idea.

You should abstract out the function to include in the rest of your JavaScript code from the data returned by Ajax methods.

For what it's worth, though, (and I don't understand why you're inserting a script block in a div?) even inline script methods written in a script block will be accessible.

Single liner works

df['Name'] = 'abc'

Creates a Name column and sets all rows to abc value

Fiddle

 .row-seperator{
   border-top: solid transparent 50px;
 }

<table>
   <tr><td>Section 1</td></tr>
   <tr><td>row1 1</td></tr>
   <tr><td>row1 2</td></tr>
   <tr>
      <td class="row-seperator">Section 2</td>
   </tr>
   <tr><td>row2 1</td></tr>
   <tr><td>row2 2</td></tr>
</table>


#Outline
Section 1
row1 1
row1 2


Section 2
row2 1
row2 2

this can be another solution

Just put your data into an Object like this:

var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];

Afterwards stringify it via:

var myString = JSON.stringify(myObject);

You don't need jQuery for this. It's pure JS.

This fixed my problem but it crashed unless I changed

action:@selector(switchToNewsDetails:event:)                 

to

action:@selector(switchToNewsDetails: forEvent:)              

If another part of your code has already made a connection with the same socket and UUID, you get this error.

pip install -r requirements.txt for python 2.x

You could use HTML's indeterminate IDL attribute on input elements.

You can use string.punctuation with built-in NLTK stopwords list:

from nltk.tokenize import word_tokenize, sent_tokenize
from nltk.corpus import stopwords
from string import punctuation

words = tokenize(text)
wordsWOStopwords = removeStopWords(words)

def tokenize(text):
        sents = sent_tokenize(text)
        return [word_tokenize(sent) for sent in sents]

def removeStopWords(words):
        customStopWords = set(stopwords.words('english')+list(punctuation))
        return [word for word in words if word not in customStopWords]

NLTK stopwords complete list

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

Your query contains columns which could be present with the same name in more than one table you are referencing, hence the not unique error. It's best if you make the references explicit and/or use table aliases when joining.

Try

    SELECT pa.ProjectID, p.Project_Title, a.Account_ID, a.Username, a.Access_Type, c.First_Name, c.Last_Name
      FROM Project_Assigned pa
INNER JOIN Account a
        ON pa.AccountID = a.Account_ID
INNER JOIN Project p
        ON pa.ProjectID = p.Project_ID
INNER JOIN Clients c
        ON a.Account_ID = c.Account_ID
     WHERE a.Access_Type = 'Client';

it seams that your ending quote comes too early. It should be after the last parameter.

This trick worked for me.

I noticed something interesting: when I start my application using the following command line:

java -Dcom.sun.management.jmxremote.port=9999
     -Dcom.sun.management.jmxremote.authenticate=false
     -Dcom.sun.management.jmxremote.ssl=false

If I try to connect to this port from a remote machine using jconsole, the TCP connection succeeds, some data is exchanged between remote jconsole and local jmx agent where my MBean is deployed, and then, jconsole displays a connect error message. I performed a wireshark capture, and it shows data exchange coming from both agent and jconsole.

Thus, this is not a network issue, if I perform a netstat -an with or without java.rmi.server.hostname system property, I have the following bindings:

 TCP    0.0.0.0:9999           0.0.0.0:0              LISTENING
 TCP    [::]:9999              [::]:0                 LISTENING

It means that in both cases the socket created on port 9999 accepts connections from any host on any address.

I think the content of this system property is used somewhere at connection and compared with the actual IP address used by agent to communicate with jconsole. And if those address do not match, connection fails.

I did not have this problem while connecting from the same host using jconsole, only from real physical remote hosts. So, I suppose that this check is done only when connection is coming from the "outside".

To get a pure hex value this might be useful. It's based on Joe's answer:

def gethex(decimal):
    return hex(decimal)[2:]

Please call trigger function any where and button will click.

<a href="#" id="myBtn" title="" >Button click </a>

function trigger(){
    document.getElementById("myBtn").click();
}

The other answers are entirely correct, but this answer provides some extra detalis, I think.

Consider this example:

using System;

static class Program {
  static void Main() {
    try {
      ThrowTest();
    } catch (Exception e) {
      Console.WriteLine("Your stack trace:");
      Console.WriteLine(e.StackTrace);
      Console.WriteLine();
      if (e.InnerException == null) {
        Console.WriteLine("No inner exception.");
      } else {
        Console.WriteLine("Stack trace of your inner exception:");
        Console.WriteLine(e.InnerException.StackTrace);
      }
    }
  }

  static void ThrowTest() {
    decimal a = 1m;
    decimal b = 0m;
    try {
      Mult(a, b);  // line 34
      Div(a, b);   // line 35
      Mult(b, a);  // line 36
      Div(b, a);   // line 37
    } catch (ArithmeticException arithExc) {
      Console.WriteLine("Handling a {0}.", arithExc.GetType().Name);

      //   uncomment EITHER
      //throw arithExc;
      //   OR
      //throw;
      //   OR
      //throw new Exception("We handled and wrapped your exception", arithExc);
    }
  }

  static void Mult(decimal x, decimal y) {
    decimal.Multiply(x, y);
  }
  static void Div(decimal x, decimal y) {
    decimal.Divide(x, y);
  }
}

If you uncomment the throw arithExc; line, your output is:

Handling a DivideByZeroException.
Your stack trace:
   at Program.ThrowTest() in c:\somepath\Program.cs:line 44
   at Program.Main() in c:\somepath\Program.cs:line 9

No inner exception.

Certainly, you have lost information about where that exception happened. If instead you use the throw; line, this is what you get:

Handling a DivideByZeroException.
Your stack trace:
   at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
   at System.Decimal.Divide(Decimal d1, Decimal d2)
   at Program.Div(Decimal x, Decimal y) in c:\somepath\Program.cs:line 58
   at Program.ThrowTest() in c:\somepath\Program.cs:line 46
   at Program.Main() in c:\somepath\Program.cs:line 9

No inner exception.

This is a lot better, because now you see that it was the Program.Div method that caused you problems. But it's still hard to see if this problem comes from line 35 or line 37 in the try block.

If you use the third alternative, wrapping in an outer exception, you lose no information:

Handling a DivideByZeroException.
Your stack trace:
   at Program.ThrowTest() in c:\somepath\Program.cs:line 48
   at Program.Main() in c:\somepath\Program.cs:line 9

Stack trace of your inner exception:
   at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
   at System.Decimal.Divide(Decimal d1, Decimal d2)

In particular you can see that it's line 35 that leads to the problem. However, this requires people to search the InnerException, and it feels somewhat indirect to use inner exceptions in simple cases.

In this blog post they preserve the line number (line of the try block) by calling (through reflection) the internal intance method InternalPreserveStackTrace() on the Exception object. But it's not nice to use reflection like that (the .NET Framework might change their internal members some day without warning).

If you are using SolrSharp, it does not support negative queries.

You need to change QueryParameter.cs (Create a new parameter)

private bool _negativeQuery = false;

public QueryParameter(string field, string value, ParameterJoin parameterJoin = ParameterJoin.AND, bool negativeQuery = false)
{
    this._field = field;
    this._value = value.Trim();
    this._parameterJoin = parameterJoin;
    this._negativeQuery = negativeQuery;
}

public bool NegativeQuery
{
    get { return _negativeQuery; }
    set { _negativeQuery = value; }
}

And in QueryParameterCollection.cs class, the ToString() override, looks if the Negative parameter is true

arQ[x] = (qp.NegativeQuery ? "-(" : "(") + qp.ToString() + ")" + (qp.Boost != 1 ? "^" + qp.Boost.ToString() : "");

When you call the parameter creator, if it's a negative value. Simple change the propertie

List<QueryParameter> QueryParameters = new List<QueryParameter>();
QueryParameters.Add(new QueryParameter("PartnerList", "[* TO *]", ParameterJoin.AND, true));

Try this:

#include <stdio.h>
#include <unistd.h>
#include <string.h> /* for strncpy */

#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netinet/in.h>
#include <net/if.h>
#include <arpa/inet.h>

int
main()
{
 int fd;
 struct ifreq ifr;

 fd = socket(AF_INET, SOCK_DGRAM, 0);

 /* I want to get an IPv4 IP address */
 ifr.ifr_addr.sa_family = AF_INET;

 /* I want IP address attached to "eth0" */
 strncpy(ifr.ifr_name, "eth0", IFNAMSIZ-1);

 ioctl(fd, SIOCGIFADDR, &ifr);

 close(fd);

 /* display result */
 printf("%s\n", inet_ntoa(((struct sockaddr_in *)&ifr.ifr_addr)->sin_addr));

 return 0;
}

The code sample is taken from here.

Here's something I quickly just made and it should perform far better than File.getName().endsWith(".xxxx");

import java.io.File;
import java.io.FileFilter;

public class ExtensionsFilter implements FileFilter 
{
    private char[][] extensions;

    private ExtensionsFilter(String[] extensions)
    {
        int length = extensions.length;
        this.extensions = new char[length][];
        for (String s : extensions)
        {
            this.extensions[--length] = s.toCharArray();
        }
    }

    @Override
    public boolean accept(File file)
    {
        char[] path = file.getPath().toCharArray();
        for (char[] extension : extensions)
        {
            if (extension.length > path.length)
            {
                continue;
            }
            int pStart = path.length - 1;
            int eStart = extension.length - 1;
            boolean success = true;
            for (int i = 0; i <= eStart; i++)
            {
                if ((path[pStart - i] | 0x20) != (extension[eStart - i] | 0x20))
                {
                    success = false;
                    break;
                }
            }
            if (success)
                return true;
        }
        return false;
    }
}

Here's an example for various images formats.

private static final ExtensionsFilter IMAGE_FILTER = 
      new ExtensionsFilter(new String[] {".png", ".jpg", ".bmp"});

int iInt = 10;
Integer iInteger = new Integer(iInt);

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

Swift 3.0 and Swift 4.1

1- Register the notification in the viewWillAppear method:

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: .UIKeyboardWillShow, object: nil)

2- Method to be called:

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        let keyboardHeight = keyboardSize.height
        print(keyboardHeight)
    }
}

For performance this might help:

    private static Dictionary<Type, Dictionary<string, object>> dicEnum = new Dictionary<Type, Dictionary<string, object>>();
    public static T ToEnum<T>(this string value, T defaultValue)
    {
        var t = typeof(T);
        Dictionary<string, object> dic;
        if (!dicEnum.ContainsKey(t))
        {
            dic = new Dictionary<string, object>();
            dicEnum.Add(t, dic);
            foreach (var en in Enum.GetValues(t))
                dic.Add(en.ToString(), en);
        }
        else
            dic = dicEnum[t];
        if (!dic.ContainsKey(value))
            return defaultValue;
        else
            return (T)dic[value];
    }

create-react-app and react-scripts

react-scripts is a set of scripts from the create-react-app starter pack. create-react-app helps you kick off projects without configuring, so you do not have to setup your project by yourself.

react-scripts start sets up the development environment and starts a server, as well as hot module reloading. You can read here to see what everything it does for you.

with create-react-app you have following features out of the box.

• React, JSX, ES6, and Flow syntax support.
• Language extras beyond ES6 like the object spread operator.
• Autoprefixed CSS, so you don’t need -webkit- or other prefixes.
• A fast interactive unit test runner with built-in support for coverage reporting.
• A live development server that warns about common mistakes.
• A build script to bundle JS, CSS, and images for production, with hashes and sourcemaps.
• An offline-first service worker and a web app manifest, meeting all the Progressive Web App criteria.
• Hassle-free updates for the above tools with a single dependency.

npm scripts

npm start is a shortcut for npm run start.

npm run is used to run scripts that you define in the scripts object of your package.json

if there is no start key in the scripts object, it will default to node server.js

Sometimes you want to do more than the react scripts gives you, in this case you can do react-scripts eject. This will transform your project from a "managed" state into a not managed state, where you have full control over dependencies, build scripts and other configurations.

I use [^\t\r\n\x20-\x7E]+ and that seems to be working fine.

The better pattern is to create a standalone BroadcastReceiver. This insures that your app can respond to the broadcast, whether or not the Service is running. In fact, using this pattern may remove the need for a constant-running Service altogether.

Register the BroadcastReceiver in your Manifest, and create a separate class/file for it.

Eg:

<receiver android:name=".FooReceiver" >
    <intent-filter >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

When the receiver runs, you simply pass an Intent (Bundle) to the Service, and respond to it in onStartCommand().

Eg:

public class FooReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // do your work quickly!
        // then call context.startService();
    }   
}

When you assign your variables "first_number" and "second_number", you need to change "document.getElementsById" to the singular "document.getElementById".

    var myObj = [];
    myObj['Base'] = [];
    myObj['Base']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['Base']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };

    myObj['SC1'] = [];
    myObj['SC1']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['SC1']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };


    console.log(myObj);

    if ('Base' in myObj) {
      console.log('Base found');

      if ('Base.panel.panel_base' in myObj['Base'])  {
        console.log('Base.panel.panel_base found'); 


      console.log('old value: ' + myObj['Base']['Base.panel.panel_base'].Context);  
      myObj['Base']['Base.panel.panel_base'] = 'new Value';
      console.log('new value: ' + myObj['Base']['Base.panel.panel_base']);
      }
    }

Output:

• Base found
• Base.panel.panel_base found
• old value: Base
• new value: new Value

The array operation works. There is no problem.

Iteration:

     Object.keys(myObj['Base']).forEach(function(key, index) {            
        var value = objcons['Base'][key];                   
      }, myObj);

There are 3 ways to do this:

1. Define the Series names directly

Right-click on the Chart and click Select Data then edit the series names directly as shown below.

You can either specify the values directly e.g. Series 1 or specify a range e.g. =A2

2. Create a chart defining upfront the series and axis labels

Simply select your data range (in similar format as I specified) and create a simple bar chart. The labels should be defined automatically.

3. Define the legend (series names) using VBA

Similarly you can define the series names dynamically using VBA. A simple example below:

ActiveChart.ChartArea.Select
ActiveChart.FullSeriesCollection(1).Name = "=""Hello"""

This will redefine the first series name. Just change the index from (1) to e.g. (2) and so on to change the following series names. What does the VBA above do? It sets the series name to Hello as "=""Hello""" translates to ="Hello" (" have to be escaped by a preceding ").
