template <typename T>
const T to(const string& sval)
{
        T val;
        stringstream ss;
        ss << sval;
        ss >> val;
        if(ss.fail())
                throw runtime_error((string)typeid(T).name() + " type wanted: " + sval);
        return val;
}

And then you can use it like that:

double d = to<double>("4.3");

or

int i = to<int>("4123");

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.

???????

yourStringStream.str()

In this line:

const char* cstr2 = ss.str().c_str();

ss.str() will make a copy of the contents of the stringstream. When you call c_str() on the same line, you'll be referencing legitimate data, but after that line the string will be destroyed, leaving your char* to point to unowned memory.

You can create a MemoryStream from a String and use that in any third-party function that requires a stream. In this case, MemoryStream, with the help of UTF8.GetBytes, provides the functionality of Java's StringStream.

From String examples

String content = "stuff";
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(content)))
{
    Print(stream); //or whatever action you need to perform with the stream
    stream.Seek(0, SeekOrigin.Begin); //If you need to use the same stream again, don't forget to reset it.
    UseAgain(stream);
}

To String example

stream.Seek(0, SeekOrigin.Begin);
string s;
using (var readr = new StreamReader(stream))
{
    s = readr.ReadToEnd();
}
//and don't forget to dispose the stream if you created it

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

abc
def
ghi

You probably have a forward declaration of the class, but haven't included the header:

#include <sstream>

//...
QString Stats_Manager::convertInt(int num)
{
    std::stringstream ss;   // <-- also note namespace qualification
    ss << num;
    return ss.str();
}

An incomplete type error is when the compiler encounters the use of an identifier that it knows is a type, for instance because it has seen a forward-declaration of it (e.g. class stringstream;), but it hasn't seen a full definition for it (class stringstream { ... };).

This could happen for a type that you haven't used in your own code but is only present through included header files -- when you've included header files that use the type, but not the header file where the type is defined. It's unusual for a header to not itself include all the headers it needs, but not impossible.

For things from the standard library, such as the stringstream class, use the language standard or other reference documentation for the class or the individual functions (e.g. Unix man pages, MSDN library, etc.) to figure out what you need to #include to use it and what namespace to find it in if any. You may need to search for pages where the class name appears (e.g. man -k stringstream).

Actually it's a bug and nobody found a workaround so far. An issue has been created. The bug is still here in honeycomb.

Please star it if you think it's important : http://code.google.com/p/android/issues/detail?id=14749

If I had a script.sh and i wanted to execute it from bash and leave it running even when I want to close my bash session then I would combine nohup and & at the end.

example: nohup ./script.sh < inputFile.txt > ./logFile 2>&1 &

inputFile.txt can be any file. If your file has no input then we usually use /dev/null. So the command would be:

nohup ./script.sh < /dev/null > ./logFile 2>&1 &

After that close your bash session,open another terminal and execute: ps -aux | egrep "script.sh" and you will see that your script is still running at the background. Of cource,if you want to stop it then execute the same command (ps) and kill -9 <PID-OF-YOUR-SCRIPT>

In addition to Doug Kavendek answer. One could use the following approach to get closer to tz_database.

1. Download [Free Zip Code Latitude and Longitude Database]
2. Download [A shapefile of the TZ timezones of the world]
3. Use any free library for shapefile querying (e.g. .NET Easy GIS .NET, LGPL).

    var shapeFile = new ShapeFile(shapeFilePath);
    var shapeIndex = shapeFile.GetShapeIndexContainingPoint(new PointD(long, lat), 0D);
    var attrValues = shapeFile.GetAttributeFieldValues(shapeIndex);
    var timeZoneId = attrValues[0];

P.S. Can't insert all the links :( So please use search.

async methods are different than normal methods. Whatever you return from async methods are wrapped in a Task.

If you return no value(void) it will be wrapped in Task, If you return int it will be wrapped in Task<int> and so on.

If your async method needs to return int you'd mark the return type of the method as Task<int> and you'll return plain int not the Task<int>. Compiler will convert the int to Task<int> for you.

private async Task<int> MethodName()
{
    await SomethingAsync();
    return 42;//Note we return int not Task<int> and that compiles
}

Sameway, When you return Task<object> your method's return type should be Task<Task<object>>

public async Task<Task<object>> MethodName()
{
     return Task.FromResult<object>(null);//This will compile
}

Since your method is returning Task, it shouldn't return any value. Otherwise it won't compile.

public async Task MethodName()
{
     return;//This should work but return is redundant and also method is useless.
}

Keep in mind that async method without an await statement is not async.

innerHTML is not standard and may not work in some browsers. I have used html() in all browsers with no problem.

I'd prefer mapping after making sure the value is available

private String getStringIfObjectIsPresent(Optional<Object> object) {
   Object ob = object.orElseThrow(MyCustomException::new);
    // do your mapping with ob
   String result = your-map-function(ob);
  return result;
}

or one liner

private String getStringIfObjectIsPresent(Optional<Object> object) {
   return your-map-function(object.orElseThrow(MyCustomException::new));
}

As a noobie I was confused by this until I realized that the so called "path" is the path relative to the MyClass.class file in the file system and not the MyClass.java file. My IDE copies the resources (like xx.jpg, xx.xml) to a directory local to the MyClass.class. For example, inside a pkg directory called "target/classes/pkg. The class-file location may be different for different IDE's and depending on how the build is structured for your application. You should first explore the file system and find the location of the MyClass.class file and the copied location of the associated resource you are seeking to extract. Then determine the path relative to the MyClass.class file and write that as a string value with "dots" and "slashes".

For example, here is how I make an app1.fxml file available to my javafx application where the relevant "MyClass.class" is implicitly "Main.class". The Main.java file is where this line of resource-calling code is contained. In my specific case the resources are copied to a location at the same level as the enclosing package folder. That is: /target/classes/pkg/Main.class and /target/classes/app1.fxml. So paraphrasing...the relative reference "../app1.fxml" is "start from Main.class, go up one directory level, now you can see the resource".

FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("../app1.fxml"));

Note that in this relative-path string "../app1.fxml", the first two dots reference the directory enclosing Main.class and the single "." indicates a file extension to follow. After these details become second nature, you will forget why it was confusing.

My answer refers to a special case of the general problem the OP describes, but I'll add it just in case it helps somebody out.

When using @EnableOAuth2Sso, Spring puts an OAuth2RestTemplate on the application context, and this component happens to assume thread-bound servlet-related stuff.

My code has a scheduled async method that uses an autowired RestTemplate. This isn't running inside DispatcherServlet, but Spring was injecting the OAuth2RestTemplate, which produced the error the OP describes.

The solution was to do name-based injection. In the Java config:

@Bean
public RestTemplate pingRestTemplate() {
    return new RestTemplate();
}

and in the class that uses it:

@Autowired
@Qualifier("pingRestTemplate")
private RestTemplate restTemplate;

Now Spring injects the intended, servlet-free RestTemplate.

It's available in the HTTP referer header. You can get it in a servlet as follows:

String referrer = request.getHeader("referer"); // Yes, with the legendary misspelling.

You, however, need to realize that this is a client-controlled value and can thus be spoofed to something entirely different or even removed. Thus, whatever value it returns, you should not use it for any critical business processes in the backend, but only for presentation control (e.g. hiding/showing/changing certain pure layout parts) and/or statistics.

For the interested, background about the misspelling can be found in Wikipedia.

If the string is from a trusted source, you could use eval then JSON.stringify the result. Like this:

var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }";
var json = JSON.stringify(eval("(" + str + ")"));

Note that when you eval an object literal, it has to be wrapped in parentheses, otherwise the braces are parsed as a block instead of an object.

I also agree with the comments under the question that it would be much better to just encode the object in valid JSON to begin with and avoid having to parse, encode, then presumably parse it again. HTML supports single-quoted attributes (just be sure to HTML-encode any single quotes inside strings).

I'm not sure I have followed your question- are you trying to attach a child view to the RelativeLayout? If so you want to do something along the lines of:

RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, null);
item.addView(child);

Or one can simply use: $('#myElem').valid()

if ($('#myElem').valid()){
   // will also trigger unobtrusive validation only for this element if in place 
   // add your extra logic here to execute only when element is valid
}

Note that validate() needs to be called on the form before checking it using this method.

Documentation link: https://jqueryvalidation.org/valid/

Generally speaking the way to center a black level element (like a <ul>) is using the margin:auto; property.

To align text and inline level elements within a block level element use text-align:center;. So all together something like...

ul {
    margin:auto;
}
ul li {
    text-align:center;
    list-style-position:inside; /* so that the bullet points are also centered */
}
ul li div {
    display:inline; /* so that the bullet points aren't above the content */
}

... should work.

The fringe case is Internet Explorer6... or even other IEs when not using a <!DOCTYPE>. IE6 incorrectly aligns block level elemnts using text-align. So if you're looking to support IE6 (or not using a <!DOCTYPE>) your full solution is...

div.topmenu-design {
    text-align:center;
}
div.topmenu-design ul {
    margin:auto;
}
div.topmenu-design ul li {
    text-align:center;
    list-style-position:inside; /* so that the bullet points are also centered */
}
div.topmenu-design ul li div {
    display:inline; /* so that the bullet points aren't above the content */
}

As a footnote, I think id="topmenu firstlevel" is invalid as an id attribute can't contain spaces... ? Indeed the w3c recommendation defines the id attribute as a 'name' type...

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

The problem shall have solved if you specify your path.

e.g.

"require 'st.rb'" --> "require './st.rb'"

See if your problem get solved or not.

In Go, you can multiply variables of same type, so you need to have both parts of the expression the same type.

The simplest thing you can do is casting an integer to duration before multiplying, but that would violate unit semantics. What would be multiplication of duration by duration in term of units?

I'd rather convert time.Millisecond to an int64, and then multiply it by the number of milliseconds, then cast to time.Duration:

time.Duration(int64(time.Millisecond) * int64(rand.Int31n(1000)))

This way any part of the expression can be said to have a meaningful value according to its type. int64(time.Millisecond) part is just a dimensionless value - the number of smallest units of time in the original value.

If walk a slightly simpler path:

time.Duration(rand.Int31n(1000)) * time.Millisecond

The left part of multiplication is nonsense - a value of type "time.Duration", holding something irrelevant to its type:

numberOfMilliseconds := 100
// just can't come up with a name for following:
someLHS := time.Duration(numberOfMilliseconds)
fmt.Println(someLHS)
fmt.Println(someLHS*time.Millisecond)

And it's not just semantics, there is actual functionality associated with types. This code prints:

100ns
100ms

Interestingly, the code sample here uses the simplest code, with the same misleading semantics of Duration conversion: https://golang.org/pkg/time/#Duration

seconds := 10

fmt.Print(time.Duration(seconds)*time.Second) // prints 10s

Couldn't find any solution that had good syntax highlighting for the console, so here's my 2p

Install & Add cli-highlight dependency

npm install cli-highlight --save

Define logjson globally

const highlight = require('cli-highlight').highlight
console.logjson = (obj) => console.log(
                               highlight( JSON.stringify(obj, null, 4), 
                                          { language: 'json', ignoreIllegals: true } ));

Use

console.logjson({foo: "bar", someArray: ["string1", "string2"]});

I resolved a similar issue in my getClass function like this:

import { ApiGateway } from './api-gateway.class';
import { AppSync } from './app-sync.class';
import { Cognito } from './cognito.class';

export type stackInstances = typeof ApiGateway | typeof  AppSync | typeof Cognito

export const classes = {
  ApiGateway,
  AppSync,
  Cognito
} as {
  [key: string]: stackInstances
};

export function getClass(name: string) {
  return classes[name];
}

Typing my classes const with my union type made typescript happy and it makes sense to me.

On the realisation that you're unfamiliar with colspan, I presumed you're also unfamiliar with rowspan, so I thought I'd throw that in for free.

One important point to note, when using rowspan: the following tr elements must contain fewer td elements, because of the cells using rowspan in the previous row (or previous rows).

table {_x000D_
  border: 1px solid #000;_x000D_
  border-collapse: collapse;_x000D_
}_x000D_
_x000D_
th,_x000D_
td {_x000D_
  border: 1px solid #000;_x000D_
}

<table>_x000D_
  <thead>_x000D_
    <tr>_x000D_
      <th colspan="2">Column one and two</th>_x000D_
      <th>Column three</th>_x000D_
    </tr>_x000D_
  </thead>_x000D_
  <tbody>_x000D_
    <tr>_x000D_
      <td rowspan="2" colspan="2">A large cell</td>_x000D_
      <td>a smaller cell</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
      <!-- note that this row only has _one_ td, since the preceding row_x000D_
                     takes up some of this row -->_x000D_
      <td>Another small cell</td>_x000D_
    </tr>_x000D_
  </tbody>_x000D_
</table>

Install Pillow from Command Line:

python -m pip install pillow

There is a ToArray() function on Values:

Foo[] arr = new Foo[dict.Count];    
dict.Values.CopyTo(arr, 0);

But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:

IEnumerable<Foo> foos = dict.Values;

Basically you have two ways to iterate over all elements:

1. Using recursion (the most common way I think):

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
        .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));
    doSomething(document.getDocumentElement());
}

public static void doSomething(Node node) {
    // do something with the current node instead of System.out
    System.out.println(node.getNodeName());

    NodeList nodeList = node.getChildNodes();
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentNode = nodeList.item(i);
        if (currentNode.getNodeType() == Node.ELEMENT_NODE) {
            //calls this method for all the children which is Element
            doSomething(currentNode);
        }
    }
}

2. Avoiding recursion using getElementsByTagName() method with * as parameter:

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
            .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));

    NodeList nodeList = document.getElementsByTagName("*");
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node node = nodeList.item(i);
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            // do something with the current element
            System.out.println(node.getNodeName());
        }
    }
}

I think these ways are both efficient.
Hope this helps.

I know that its late but it might be helpful for people who need to change the Bundle Identifier of the app. In the finder go to the project folder:

the project file --> Right click on your project file '*.xcodeproj' 

--> choose 'Show Package Contents' 
--> Double click to open 'project.pbxproj' file 

--> find 'productName = NAME_YOU_WANT_TO_CHANGE' in the 
    '/* Begin PBXNativeTarget section */'

The ${PRODUCT_NAME:rfc1034identifier} variable will be replaced with the name you have entered and new Bundle Identifier will be updated to what you need it to be.

formatter = new SimpleDateFormat("dd-MMM-yy");

Here's a transcription of another answer I gave to a similar question:

If you apply utf8_encode() to an already UTF8 string it will return a garbled UTF8 output.

I made a function that addresses all this issues. It´s called Encoding::toUTF8().

You dont need to know what the encoding of your strings is. It can be Latin1 (iso 8859-1), Windows-1252 or UTF8, or the string can have a mix of them. Encoding::toUTF8() will convert everything to UTF8.

I did it because a service was giving me a feed of data all messed up, mixing UTF8 and Latin1 in the same string.

Usage:

$utf8_string = Encoding::toUTF8($utf8_or_latin1_or_mixed_string);

$latin1_string = Encoding::toLatin1($utf8_or_latin1_or_mixed_string);

Download:

https://github.com/neitanod/forceutf8

Update:

I've included another function, Encoding::fixUFT8(), wich will fix every UTF8 string that looks garbled.

Usage:

$utf8_string = Encoding::fixUTF8($garbled_utf8_string);

Examples:

echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂédÃÂération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");

will output:

Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football

Update: I've transformed the function (forceUTF8) into a family of static functions on a class called Encoding. The new function is Encoding::toUTF8().

GSON is easy to use and has relatively small memory footprint. If you loke to have even smaller footprint, you can grab:

https://github.com/ko5tik/jsonserializer

Which is tiny wrapper around stripped down GSON libraries for just POJOs

You can easily do so with SASS pre-processor by using @extend.

someDiv {
    @extend .opacity;
    @extend .radius;
}

Ohterwise, you could use JavaScript (jQuery) as well:

$('someDiv').addClass('opacity radius')

The easiest is of course to add multiple classes right in the HTML

<div class="opacity radius">

.example.com TRUE / FALSE 1560211200 MY_VARIABLE MY_VALUE

The cookies file format apparently consists of a line per cookie and each line consists of the following seven tab-delimited fields:

• domain - The domain that created AND that can read the variable.
• flag - A TRUE/FALSE value indicating if all machines within a given domain can access the variable. This value is set automatically by the browser, depending on the value you set for domain.
• path - The path within the domain that the variable is valid for.
• secure - A TRUE/FALSE value indicating if a secure connection with the domain is needed to access the variable.
• expiration - The UNIX time that the variable will expire on. UNIX time is defined as the number of seconds since Jan 1, 1970 00:00:00 GMT.
• name - The name of the variable.
• value - The value of the variable.

Currently you can't access the arrays named name and country, because they are member variables of your Athelete class.

Based on what it looks like you're trying to do, this will not work.

These arrays belong in your main class.

The reader acts like a generator. On a file with some fake data:

>>> import sys, csv
>>> data = csv.reader(open('data.csv'),delimiter=';')
>>> data
<_csv.reader object at 0x1004a11a0>
>>> data.next()
['a', ' b', ' c']
>>> data.next()
['x', ' y', ' z']
>>> data.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

Using operator.itemgetter as Ignacio suggests:

>>> data = csv.reader(open('data.csv'),delimiter=';')
>>> import operator
>>> sortedlist = sorted(data, key=operator.itemgetter(2), reverse=True)
>>> sortedlist
[['x', ' y', ' z'], ['a', ' b', ' c']]

Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:

public class CtorTest {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }
    }

    private static class Sub extends Base {
        public Sub() {
            System.err.println("In Sub ctor");
        }
    }
}

If you want to explicitly call a constructor from a super class, you need to do something like this:

public class Ctor2Test {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }

        public Base(final String toPrint) {
            System.err.println("In Base ctor.  To Print: " + toPrint);
        }
    }

    private static class Sub extends Base {
        public Sub() {
            super("Hello World!");
            System.err.println("In Sub ctor");
        }
    }
}

The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

The followed works on ubuntu 12.04:

pip uninstall PIL
apt-get install libjpeg-dev
apt-get install libfreetype6-dev
apt-get install zlib1g-dev
apt-get install libpng12-dev
pip install PIL --upgrade

when your see "-- JPEG support avaliable" that means it works.

But, if it still doesn't work when your edit your jpeg image, check the python path !! my python path missed /usr/local/lib/python2.7/dist-packages/PIL-1.1.7-py2.7-linux-x86_64.egg/, so I edit the ~/.bashrc add the following code to this file:

Edit: export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages/PIL-1.1.7-py2.7-linux-x86_64.egg/

then, finally, it works!!

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

As you may have already figured, Asp.Net MVC is a different paradigm than Asp.Net (webforms). Accessing form elements between the server and client take a different approach in Asp.Net MVC.

You can google more reading material on this on the web. For now, I would suggest using Ajax to get or post data to the server. You can still employ input type="hidden", but initialize it with a value from the ViewData or for Razor, ViewBag.

For example, your controller may look like this:

public ActionResult Index()
{
     ViewBag.MyInitialValue = true;
     return View();
} 

In your view, you can have an input elemet that is initialized by the value in your ViewBag:

<input type="hidden" name="myHiddenInput" id="myHiddenInput" value="@ViewBag.MyInitialValue" />

Then you can pass data between the client and server via ajax. For example, using jQuery:

$.get('GetMyNewValue?oldValue=' + $('#myHiddenInput').val(), function (e) {
   // blah
});

You can alternatively use $.ajax, $.getJSON, $.post depending on your requirement.

I was looking for a just a numeric value = 6.84 - using the other answers here I was able to limit my search to this

Declare @sourceTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000), column_name varchar(1000))
Declare @resultsTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000))

Insert into @sourceTable(table_name, column_name)
select schema_name(t.schema_id) + '.' + t.name as[table], c.name as column_name
from sys.columns c
join sys.tables t
on t.object_id = c.object_id
where type_name(user_type_id) in ('decimal', 'numeric', 'smallmoney', 'money', 'float', 'real')
order by[table], c.column_id;

DECLARE db_cursor CURSOR FOR
Select table_name, column_name from @sourceTable
DECLARE @mytablename VARCHAR(1000);
DECLARE @mycolumnname VARCHAR(1000);

OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname

WHILE @ @FETCH_STATUS = 0
BEGIN
    Insert into @ResultsTable(table_name)
    EXEC('SELECT ''' + @mytablename + '.' + @mycolumnname + '''  FROM ' + @mytablename + ' (NOLOCK) ' +
    ' WHERE ' + @mycolumnname + '=6.84')
    FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname  
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
Select Distinct(table_name) from @ResultsTable

The answer is:

gcc --version

Rather than searching on forums, for any possible option you can always type:

gcc --help

haha! :)

Double click and open the server. Go to 'Arguments'. -Dcatalina.base= .. something. Go to that something. Your logs are there.

Be careful using SqlDependency class - it has problems with memory leaks.

Just use a cross-platform, .NET 3.5, .NET Core compatible and open source solution - SqlDependencyEx. You can get notifications as well as data that was changed (you can access it through properties in notification event object). You can also tack DELETE\UPDATE\INSERT operations separately or together.

Here is an example of how easy it is to use SqlDependencyEx:

int changesReceived = 0;
using (SqlDependencyEx sqlDependency = new SqlDependencyEx(
          TEST_CONNECTION_STRING, TEST_DATABASE_NAME, TEST_TABLE_NAME)) 
{
    sqlDependency.TableChanged += (o, e) => changesReceived++;
    sqlDependency.Start();

    // Make table changes.
    MakeTableInsertDeleteChanges(changesCount);

    // Wait a little bit to receive all changes.
    Thread.Sleep(1000);
}

Assert.AreEqual(changesCount, changesReceived);

Please follow the links for details. This component was tested in many enterprise-level applications and proven to be reliable. Hope this helps.

You can use String.Remove to delete from a specified position to the end of the string.

myString = myString.Remove(myString.Length - 3);

This could be one solution.

Groovy can import other groovy classes exactly like Java does. Just be sure the extension of the library file is .groovy.

    $ cat lib/Lib.groovy
    package lib
    class Lib {
       static saySomething() { println 'something' }
       def sum(a,b) { a+b }
    }

    $ cat app.gvy
    import lib.Lib
    Lib.saySomething();
    println new Lib().sum(37,5)

    $ groovy app
    something
    42

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

A simple return statement will 'stop' or return the function; in precise terms, it 'returns' function execution to the point at which the function was called - the function is terminated without further action.

That means you could have a number of places throughout your function where it might return. Like this:

def player():
    # do something here
    check_winner_variable = check_winner()  # check something 
    if check_winner_variable == '1': 
        return
    second_test_variable = second_test()
    if second_test_variable == '1': 
        return
       
    # let the computer do something
    computer()

You can call window.focus();

but moving or losing the focus is bound to interfere with anyone using the tab key to get around the page.

you could listen for keycode 13, and forego the effect if the tab key is pressed.

editText.setFocusable(false);
editText.setClickable(false);

$('#checkbox').prop('checked', true);

When you want it unchecked:

$('#checkbox').prop('checked', false);

In math, ? means FOR ALL.

Unicode character (\u2200, ?).

1. Add a key in your info.plist file UIViewControllerBasedStatusBarAppearance and set it to YES.

2. In viewDidLoad method of your ViewController add a method call:

   [self setNeedsStatusBarAppearanceUpdate];
   

3. Then paste the following method in viewController file:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

TRY:

SELECT EXTRACT(YEAR FROM (STR_TO_DATE(subdateshow, '%d/%m/%Y')));

Maybe you want more simple and short approach. This will clear all TextBoxes too. (Except TextBoxes inside Panel or GroupBox).

 foreach (TextBox textBox in Controls.OfType<TextBox>())
    textBox.Text = "";

Here is an option with only a single comparison.

// return true if in range, otherwise false
function inRange(x, min, max) {
    return ((x-min)*(x-max) <= 0);
}

console.log(inRange(5, 1, 10));     // true
console.log(inRange(-5, 1, 10));    // false
console.log(inRange(20, 1, 10));    // false

my two cents about logic:

syntax is "old date" - :"new date", so:

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')

gives 30,

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')

gives: -40

Using no messy concatenations and padding :

'{:0{width}x}'.format(int(temp,2)), width=4)

Will give a hex representation with padding preserved

Here's an update for Swift 4 if you're simply looking to open up the mail client via a URL:

let email = "[email protected]"
if let url = URL(string: "mailto:\(email)") {
   UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

This worked perfectly fine for me :)

xmlns refers to the XML namespace

When using prefixes in XML, a so-called namespace for the prefix must be defined. The namespace is defined by the xmlns attribute in the start tag of an element. The namespace declaration has the following syntax. xmlns:prefix="URI".

Note: The namespace URI is not used by the parser to look up information.

The purpose is to give the namespace a unique name. However, often companies use the namespace as a pointer to a web page containing namespace information.

Our issue was simply the port number on the endpoint was incorrectly set to 8080. Changed it to 8443 and it worked.

yes i have done that on several rooted machines i set a debian linux on a sdcard by dd. i copy this script http://jeanmichel.gens.free.fr/etc/install on /system/bin

It's better not to .select anything in Excel, it is usually never necessary and slows down your code.

I think you might be looking for an "anchor" given the example you have.

<a href="#jump">This link will jump to the anchor named jump</a>
<a name="jump">This is where the link will jump to</a>

The focus jQuery method does something different from what you're trying to achieve.

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

usually i don't use for loop in R, but here is my solution using for loops and two packages : plyr and dostats

plyr is on cran and you can download dostats on https://github.com/halpo/dostats (may be using install_github from Hadley devtools package)

Assuming that i have your first two data.frame (Df.1 and Df.2) in csv files, you can do something like this.

require(plyr)
require(dostats)

files <- list.files(pattern = ".csv")


for (i in seq_along(files)) {

    assign(paste("Df", i, sep = "."), read.csv(files[i]))

    assign(paste(paste("Df", i, sep = ""), "summary", sep = "."), 
           ldply(get(paste("Df", i, sep = ".")), dostats, sum, min, mean, median, max))

}

Here is the output

R> Df1.summary
  .id sum min   mean median max
1   A  34   4 5.6667    5.5   8
2   B  22   1 3.6667    3.0   9
R> Df2.summary
  .id sum min   mean median max
1   A  21   1 3.5000    3.5   6
2   B  16   1 2.6667    2.5   5

Alexander's answer is great, but lacks the handling of proxies that sometimes return multiple IP's in the HTTP_X_FORWARDED_FOR header.

The real IP is usually at the end of the list, as explained here: http://en.wikipedia.org/wiki/X-Forwarded-For

The solution is a simple modification of Alexander's code:

def get_client_ip(request):
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        ip = x_forwarded_for.split(',')[-1].strip()
    else:
        ip = request.META.get('REMOTE_ADDR')
    return ip

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

   extend = function(destination, source) {   
          for (var property in source) {
            destination[property] = source[property];
          }
          return destination;
    };

Extending JavaScript

You could also add filters into the for loop.

You can resolve it by using org.springframework.web.servlet.mvc.support.RedirectAttributes.

Here is my controller sample.

@RequestMapping(method = RequestMethod.POST)
    public String eligibilityPost(
            @ModelAttribute("form") @Valid EligibiltyForm form,
            Model model,
            RedirectAttributes redirectAttributes) {
        if(eligibilityService.validateEligibility(form)){
            redirectAttributes.addFlashAttribute("form", form);
            return "redirect:<redirect to your page>";
        }
       return "eligibility";
    }

For all solutions instead of ".keyup" ".change" should be used or else the submit button wont be disabled when someone just selects data stored in cookies for any of the text fields.

I feel the most elegant these days is:

arr1.push(...arr2);

The MDN article on the spread operator mentions this nice sugary way in ES2015 (ES6):

A better push

Example: push is often used to push an array to the end of an existing array. In ES5 this is often done as:

var arr1 = [0, 1, 2];
var arr2 = [3, 4, 5];
// Append all items from arr2 onto arr1
Array.prototype.push.apply(arr1, arr2);

In ES6 with spread this becomes:

var arr1 = [0, 1, 2];
var arr2 = [3, 4, 5];
arr1.push(...arr2);

Do note that arr2 can't be huge (keep it under about 100 000 items), because the call stack overflows, as per jcdude's answer.

Okay... so i know that i'm answering to a decade question, but wanted to add something! I wanted to add a google calendar with special iframe parameters. Problem is that the calendar didn't work without it. 30 seconds is a bit short for my use, so i changed that in my own file to 15 minutes This worked for me.

<script>
window.setInterval("reloadIFrame();", 30000);
function reloadIFrame() {
 document.getElementById("calendar").src=calendar.src;

You could add it:

public static IEnumerable<T> OrderBy( this IEnumerable<T> input, string queryString) {
    //parse the string into property names
    //Use reflection to get and sort by properties
    //something like

    foreach( string propname in queryString.Split(','))
        input.OrderBy( x => GetPropertyValue( x, propname ) );

    // I used Kjetil Watnedal's reflection example
}

The GetPropertyValue function is from Kjetil Watnedal's answer

The issue would be why? Any such sort would throw exceptions at run-time, rather than compile time (like D2VIANT's answer).

If you're dealing with Linq to Sql and the orderby is an expression tree it will be converted into SQL for execution anyway.

Use MyISAM for very unimportant data or if you really need those minimal performance advantages. The read performance is not better in every case for MyISAM.

I would personally never use MyISAM at all anymore. Choose InnoDB and throw a bit more hardware if you need more performance. Another idea is to look at database systems with more features like PostgreSQL if applicable.

EDIT: For the read-performance, this link shows that innoDB often is actually not slower than MyISAM: https://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1/

Just add the following attribute to your current theme:

For example:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/orange</item>
    <item name="colorPrimaryDark">@android:color/holo_orange_dark</item>

UPDATE 23/Dec/2015: Since this answer seems to be getting a lot of upvotes, I've updated it to fix silly bugs and to generally improve the code based upon comments and feedback. See the end of the post for a list of specific improvements.

As other people have said, Cryptography is not simple so it's best to avoid "rolling your own" encryption algorithm.

You can, however, "roll your own" wrapper class around something like the built-in RijndaelManaged cryptography class.

Rijndael is the algorithmic name of the current Advanced Encryption Standard, so you're certainly using an algorithm that could be considered "best practice".

The RijndaelManaged class does indeed normally require you to "muck about" with byte arrays, salts, keys, initialization vectors etc. but this is precisely the kind of detail that can be somewhat abstracted away within your "wrapper" class.

The following class is one I wrote a while ago to perform exactly the kind of thing you're after, a simple single method call to allow some string-based plaintext to be encrypted with a string-based password, with the resulting encrypted string also being represented as a string. Of course, there's an equivalent method to decrypt the encrypted string with the same password.

Unlike the first version of this code, which used the exact same salt and IV values every time, this newer version will generate random salt and IV values each time. Since salt and IV must be the same between the encryption and decryption of a given string, the salt and IV is prepended to the cipher text upon encryption and extracted from it again in order to perform the decryption. The result of this is that encrypting the exact same plaintext with the exact same password gives and entirely different ciphertext result each time.

The "strength" of using this comes from using the RijndaelManaged class to perform the encryption for you, along with using the Rfc2898DeriveBytes function of the System.Security.Cryptography namespace which will generate your encryption key using a standard and secure algorithm (specifically, PBKDF2) based upon the string-based password you supply. (Note this is an improvement of the first version's use of the older PBKDF1 algorithm).

Finally, it's important to note that this is still unauthenticated encryption. Encryption alone provides only privacy (i.e. message is unknown to 3rd parties), whilst authenticated encryption aims to provide both privacy and authenticity (i.e. recipient knows message was sent by the sender).

Without knowing your exact requirements, it's difficult to say whether the code here is sufficiently secure for your needs, however, it has been produced to deliver a good balance between relative simplicity of implementation vs "quality". For example, if your "receiver" of an encrypted string is receiving the string directly from a trusted "sender", then authentication may not even be necessary.

If you require something more complex, and which offers authenticated encryption, check out this post for an implementation.

Here's the code:

using System;
using System.Text;
using System.Security.Cryptography;
using System.IO;
using System.Linq;

namespace EncryptStringSample
{
    public static class StringCipher
    {
        // This constant is used to determine the keysize of the encryption algorithm in bits.
        // We divide this by 8 within the code below to get the equivalent number of bytes.
        private const int Keysize = 256;

        // This constant determines the number of iterations for the password bytes generation function.
        private const int DerivationIterations = 1000;

        public static string Encrypt(string plainText, string passPhrase)
        {
            // Salt and IV is randomly generated each time, but is preprended to encrypted cipher text
            // so that the same Salt and IV values can be used when decrypting.  
            var saltStringBytes = Generate256BitsOfRandomEntropy();
            var ivStringBytes = Generate256BitsOfRandomEntropy();
            var plainTextBytes = Encoding.UTF8.GetBytes(plainText);
            using (var password = new Rfc2898DeriveBytes(passPhrase, saltStringBytes, DerivationIterations))
            {
                var keyBytes = password.GetBytes(Keysize / 8);
                using (var symmetricKey = new RijndaelManaged())
                {
                    symmetricKey.BlockSize = 256;
                    symmetricKey.Mode = CipherMode.CBC;
                    symmetricKey.Padding = PaddingMode.PKCS7;
                    using (var encryptor = symmetricKey.CreateEncryptor(keyBytes, ivStringBytes))
                    {
                        using (var memoryStream = new MemoryStream())
                        {
                            using (var cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write))
                            {
                                cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
                                cryptoStream.FlushFinalBlock();
                                // Create the final bytes as a concatenation of the random salt bytes, the random iv bytes and the cipher bytes.
                                var cipherTextBytes = saltStringBytes;
                                cipherTextBytes = cipherTextBytes.Concat(ivStringBytes).ToArray();
                                cipherTextBytes = cipherTextBytes.Concat(memoryStream.ToArray()).ToArray();
                                memoryStream.Close();
                                cryptoStream.Close();
                                return Convert.ToBase64String(cipherTextBytes);
                            }
                        }
                    }
                }
            }
        }

        public static string Decrypt(string cipherText, string passPhrase)
        {
            // Get the complete stream of bytes that represent:
            // [32 bytes of Salt] + [32 bytes of IV] + [n bytes of CipherText]
            var cipherTextBytesWithSaltAndIv = Convert.FromBase64String(cipherText);
            // Get the saltbytes by extracting the first 32 bytes from the supplied cipherText bytes.
            var saltStringBytes = cipherTextBytesWithSaltAndIv.Take(Keysize / 8).ToArray();
            // Get the IV bytes by extracting the next 32 bytes from the supplied cipherText bytes.
            var ivStringBytes = cipherTextBytesWithSaltAndIv.Skip(Keysize / 8).Take(Keysize / 8).ToArray();
            // Get the actual cipher text bytes by removing the first 64 bytes from the cipherText string.
            var cipherTextBytes = cipherTextBytesWithSaltAndIv.Skip((Keysize / 8) * 2).Take(cipherTextBytesWithSaltAndIv.Length - ((Keysize / 8) * 2)).ToArray();

            using (var password = new Rfc2898DeriveBytes(passPhrase, saltStringBytes, DerivationIterations))
            {
                var keyBytes = password.GetBytes(Keysize / 8);
                using (var symmetricKey = new RijndaelManaged())
                {
                    symmetricKey.BlockSize = 256;
                    symmetricKey.Mode = CipherMode.CBC;
                    symmetricKey.Padding = PaddingMode.PKCS7;
                    using (var decryptor = symmetricKey.CreateDecryptor(keyBytes, ivStringBytes))
                    {
                        using (var memoryStream = new MemoryStream(cipherTextBytes))
                        {
                            using (var cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read))
                            {
                                var plainTextBytes = new byte[cipherTextBytes.Length];
                                var decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length);
                                memoryStream.Close();
                                cryptoStream.Close();
                                return Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount);
                            }
                        }
                    }
                }
            }
        }

        private static byte[] Generate256BitsOfRandomEntropy()
        {
            var randomBytes = new byte[32]; // 32 Bytes will give us 256 bits.
            using (var rngCsp = new RNGCryptoServiceProvider())
            {
                // Fill the array with cryptographically secure random bytes.
                rngCsp.GetBytes(randomBytes);
            }
            return randomBytes;
        }
    }
}

The above class can be used quite simply with code similar to the following:

using System;

namespace EncryptStringSample
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Please enter a password to use:");
            string password = Console.ReadLine();
            Console.WriteLine("Please enter a string to encrypt:");
            string plaintext = Console.ReadLine();
            Console.WriteLine("");

            Console.WriteLine("Your encrypted string is:");
            string encryptedstring = StringCipher.Encrypt(plaintext, password);
            Console.WriteLine(encryptedstring);
            Console.WriteLine("");

            Console.WriteLine("Your decrypted string is:");
            string decryptedstring = StringCipher.Decrypt(encryptedstring, password);
            Console.WriteLine(decryptedstring);
            Console.WriteLine("");

            Console.WriteLine("Press any key to exit...");
            Console.ReadLine();
        }
    }
}

(You can download a simple VS2013 sample solution (which includes a few unit tests) here).

UPDATE 23/Dec/2015: The list of specific improvements to the code are:

• Fixed a silly bug where encoding was different between encrypting and decrypting. As the mechanism by which salt & IV values are generated has changed, encoding is no longer necessary.
• Due to the salt/IV change, the previous code comment that incorrectly indicated that UTF8 encoding a 16 character string produces 32 bytes is no longer applicable (as encoding is no longer necessary).
• Usage of the superseded PBKDF1 algorithm has been replaced with usage of the more modern PBKDF2 algorithm.
• The password derivation is now properly salted whereas previously it wasn't salted at all (another silly bug squished).

Regular expression

I would like to take credit for the command I wish to share but the truth is I obtained it for my own use from http://commandlinefu.com. It has the advantage that if you cd to any directory within your own home folder that is it will change all files and folders to lower case recursively please use with caution. It is a brilliant command line fix and especially useful for those multitudes of albums you have stored on your drive.

find . -depth -exec rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \;

You can specify a directory in place of the dot(.) after the find which denotes current directory or full path.

I hope this solution proves useful the one thing this command does not do is replace spaces with underscores - oh well another time perhaps.

First of all, all the reasons are subjective. It's more like a matter of taste rather than a reason.

Personally, I find heredoc quite useless and use it occasionally, most of the time when I need to get some HTML into a variable and don't want to bother with output buffering, to form an HTML email message for example.

Formatting doesn't fit general indentation rules, but I don't think it's a big deal.

       //some code at it's proper level
       $this->body = <<<HERE
heredoc text sticks to the left border
but it seems OK to me.
HERE;
       $this->title = "Feedback";
       //and so on

As for the examples in the accepted answer, it is merely cheating.
String examples, in fact, being more concise if one won't cheat on them

$sql = "SELECT * FROM $tablename
        WHERE id in [$order_ids_list]
        AND product_name = 'widgets'";

$x = 'The point of the "argument" was to illustrate the use of here documents';

randojs makes this a little more simple and readable:

console.log( rando(['January', 'February', 'March']).value );

<script src="https://randojs.com/1.0.0.js"></script>

issue the command:

SET time_zone = 'America/New_York';

(Or whatever time zone GMT+1 is.: http://www.php.net/manual/en/timezones.php)

This is the command to set the MySQL timezone for an individual client, assuming that your clients are spread accross multiple time zones.

This command should be executed before every SQL command involving dates. If your queries go thru a class, then this is easy to implement.

chmod a+x modifies the argument's mode while chmod 755 sets it. Try both variants on something that has full or no permissions and you will notice the difference.

You can use just:

Date.current

SQL Views:

View is a virtual table based on the result-set of an SQL statement and that is Stored in the database with some name.

SQL Table:

SQL table is database instance consists of fields (columns), and rows.

Check following post, author listed around seven differences between views and table

https://codechef4u.com/post/2015/09/03/sql-views-vs-tables

This works for me (Python 2)

s = "ABCD"
b = bytearray(s)

# if you print whole b, it still displays it as if its original string
print b

# but print first item from the array to see byte value
print b[0]

I have followed a different approach to solve pretty much the same problem, in my case, I made a new extension that adds PHP syntax highlighting support for Drupal-specific files (such as .module and .inc): https://github.com/mastazi/VS-code-drupal

As you can see in the code, I created a new extension rather than modifying the existing PHP extension. Obviously I declare a dependency on the PHP extension in the Drupal extension.

The advantage of doing it this way is that if there is an update to the PHP extension, my custom support for Drupal doesn't get lost in the update process.

Check it - You can try this code for your login form design as you ask thank you.

Explain css -

First, we define property font style and width And after that I have defined form id to set background image and the border And after that I have to define the header text in tag and after that I have added new and define by.New to set background properties and width. Thanks

You should be able to use the DataTable.Select() method. You can us it like this.

if(myDataTable.Select("Author = '" + AuthorName.Replace("'","''") + '").Length > 0)
    ...

The Select() funciton returns an array of DataRows for the results matching the where statement.

Add in your new column:

df$d <- list/data

Then you can reorder them.

df <- df[, c("a", "b", "d", "c")]

In theory, malloc gets memory from the operating system for this application. However, since you may only want 4 bytes, and the OS needs to work in pages (often 4k), malloc does a little more than that. It takes a page, and puts it's own information in there so it can keep track of what you have allocated and freed from that page.

When you allocate 4 bytes, for instance, malloc gives you a pointer to 4 bytes. What you may not realize is that the memory 8-12 bytes before your 4 bytes is being used by malloc to make a chain of all the memory you have allocated. When you call free, it takes your pointer, backs up to where it's data is, and operates on that.

When you free memory, malloc takes that memory block off the chain... and may or may not return that memory to the operating system. If it does, than accessing that memory will probably fail, as the OS will take away your permissions to access that location. If malloc keeps the memory ( because it has other things allocated in that page, or for some optimization ), then the access will happen to work. It's still wrong, but it might work.

DISCLAIMER: What I described is a common implementation of malloc, but by no means the only possible one.

Not sure if this is the most efficient answer, but it works for me:

import os
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = None # to avoid image size warning

imgdir = "/path/to/image/folder"
# if you want file of a specific extension (.png):
filelist = [f for f in glob.glob(imgdir + "**/*.png", recursive=True)]
savedir = "/path/to/image/folder/output"

start_pos = start_x, start_y = (0, 0)
cropped_image_size = w, h = (500, 500)

for file in filelist:
    img = Image.open(file)
    width, height = img.size

    frame_num = 1
    for col_i in range(0, width, w):
        for row_i in range(0, height, h):
            crop = img.crop((col_i, row_i, col_i + w, row_i + h))
            name = os.path.basename(file)
            name = os.path.splitext(name)[0]
            save_to= os.path.join(savedir, name+"_{:03}.png")
            crop.save(save_to.format(frame_num))
            frame_num += 1

This is mostly based on DataScienceGuy answer here

If you are using this other path a lot of the time you can fix this permanently without having to specify the path all of the time. By default, it is checking for partial views in the View folder and in the Shared folder. But say you want to add one.

Add a class to your Models folder:

public class NewViewEngine : RazorViewEngine {

   private static readonly string[] NEW_PARTIAL_VIEW_FORMATS = new[] {
      "~/Views/Foo/{0}.cshtml",
      "~/Views/Shared/Bar/{0}.cshtml"
   };

   public NewViewEngine() {
      // Keep existing locations in sync
      base.PartialViewLocationFormats = base.PartialViewLocationFormats.Union(NEW_PARTIAL_VIEW_FORMATS).ToArray();
   }
}

Then in your Global.asax.cs file, add the following line:

ViewEngines.Engines.Add(new NewViewEngine());

String value = someMethod();
switch(0) {
default:
    if ("apple".equals(value)) {
        method1();
        break;
    }
    if ("carrot".equals(value)) {
        method2();
        break;
    }
    if ("mango".equals(value)) {
        method3();
        break;
    }
    if ("orance".equals(value)) {
        method4();
        break;
    }
}

Even though this has been answered already, I'm adding this note for an alternative approach.

I wanted to place a known number of items into an array, into specific positions, as they come off of an "associative array" (i.e. an object) which by definition is not guaranteed to be in a sorted order. I wanted the resulting array to be an array of objects, but the objects to be in a specific order in the array since an array guarantees their order. So I did this.

First the source object, a JSONB string retrieved from PostgreSQL. I wanted to have it sorted by the "order" property in each child object.

var jsonb_str = '{"one": {"abbr": "", "order": 3}, "two": {"abbr": "", "order": 4}, "three": {"abbr": "", "order": 5}, "initialize": {"abbr": "init", "order": 1}, "start": {"abbr": "", "order": 2}}';

var jsonb_obj = JSON.parse(jsonb_str);

Since the number of nodes in the object is known, I first create an array with the specified length:

var obj_length = Object.keys(jsonb_obj).length;
var sorted_array = new Array(obj_length);

And then iterate the object, placing the newly created temporary objects into the desired locations in the array without really any "sorting" taking place.

for (var key of Object.keys(jsonb_obj)) {
  var tobj = {};
  tobj[key] = jsonb_obj[key].abbr;

  var position = jsonb_obj[key].order - 1;
  sorted_array[position] = tobj;
}

console.dir(sorted_array);

You can use below code:

<video width="400" controls autoplay>
    <source src="D:/mov1.mov" type="video/mp4">
</video>

this code will help you.

I have been struggling with how to add query string parameters to my URL. I couldn't make it work until I realized that I needed to add ? at the end of my URL, otherwise it won't work. This is very important as it will save you hours of debugging, believe me: been there...done that.

Below, is a simple API Endpoint that calls the Open Weather API and passes APPID, lat and lon as query parameters and return weather data as a JSON object. Hope this helps.

//Load the request module
var request = require('request');

//Load the query String module
var querystring = require('querystring');

// Load OpenWeather Credentials
var OpenWeatherAppId = require('../config/third-party').openWeather;

router.post('/getCurrentWeather', function (req, res) {
    var urlOpenWeatherCurrent = 'http://api.openweathermap.org/data/2.5/weather?'
    var queryObject = {
        APPID: OpenWeatherAppId.appId,
        lat: req.body.lat,
        lon: req.body.lon
    }
    console.log(queryObject)
    request({
        url:urlOpenWeatherCurrent,
        qs: queryObject
    }, function (error, response, body) {
        if (error) {
            console.log('error:', error); // Print the error if one occurred

        } else if(response && body) {
            console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
            res.json({'body': body}); // Print JSON response.
        }
    })
})  

Or if you want to use the querystring module, make the following changes

var queryObject = querystring.stringify({
    APPID: OpenWeatherAppId.appId,
    lat: req.body.lat,
    lon: req.body.lon
});

request({
   url:urlOpenWeatherCurrent + queryObject
}, function (error, response, body) {...})

An example might have been useful, but if I understood you correctly, this would work:

echo "Hello: world" | cut -f1 -d":"

This will convert Hello: world into Hello.

Variation of Aaron's answer. Using sed without temporary files

#!/bin/bash
VERSION=1.0.0
IMAGE=company/image
ID=$(docker build  -t ${IMAGE}  .  | tail -1 | sed 's/.*Successfully built \(.*\)$/\1/')

docker tag ${ID} ${IMAGE}:${VERSION}
docker tag -f ${ID} ${IMAGE}:latest

I wonder why the best answer that I've found is only in the comments! (by Daenyth with 86 up votes)

git reset --hard origin

This command will sync the local repository with the remote repository getting rid of every change you have made on your local. You can also do the following to fetch the exact branch that you have in the origin.

git reset --hard origin/<branch>

// implicit cast
var value = parseInt(tbb*1); // see original question

Explanation, for those who don't find it trivial:

Multiplying by one, a method called "implicit cast", attempts to turn the unknown type operand into the primitive type 'number'. In particular, an empty string would become number 0, making it an eligible type for parseInt()...

A very good example was also given above by PirateApp, who suggested to prepend the + sign, forcing JavaScript to use the Number implicit cast.

Aug. 20 update: parseInt("0"+expr); gives better results, in particular for parseInt("0"+'str');

let propertyName= data['propertyName'];

Simple Version from the Docs

Works particularly great for Google Earth Studio images:

ffmpeg -framerate 24 -i Project%03d.png Project.mp4

Put it in the init() function for your plugin.

function your_namespace() {
    wp_register_style('your_namespace', plugins_url('style.css',__FILE__ ));
    wp_enqueue_style('your_namespace');
    wp_register_script( 'your_namespace', plugins_url('your_script.js',__FILE__ ));
    wp_enqueue_script('your_namespace');
}

add_action( 'admin_init','your_namespace');

It took me also some time before I found the (for me) best solution which is foolproof imho.

Cheers

1. Static inner class cannot access non-static members of enclosing class. It can directly access static members (instance field and methods) of enclosing class same like the procedural style of getting value without creating object.

2. Static inner class can declare both static and non-static members. The static methods have access to static members of main class. However, it cannot access non-static inner class members. To access members of non-static inner class, it has to create object of non-static inner class.

3. Non-static inner class cannot declare static field and static methods. It has to be declared in either static or top level types. You will get this error on doing so saying "static fields only be declared in static or top level types".

4. Non-static inner class can access both static and non-static members of enclosing class in procedural style of getting value, but it cannot access members of static inner class.

5. The enclosing class cannot access members of inner classes until it creates an object of inner classes. IF main class in accessing members of non-static class it can create object of non-static inner class.

6. If main class in accessing members of static inner class it has two cases:

   • Case 1: For static members, it can use class name of static inner class
   • Case 2: For non-static members, it can create instance of static inner class.

Yeah, I know this is an 8 year-old question, but I was told that it was possible to statically link against a shared-object library and this was literally the top hit when I searched for more information about it.

To actually demonstrate that statically linking a shared-object library is not possible with ld (gcc's linker) -- as opposed to just a bunch of people insisting that it's not possible -- use the following gcc command:

gcc -o executablename objectname.o -Wl,-Bstatic -l:libnamespec.so

(Of course you'll have to compile objectname.o from sourcename.c, and you should probably make up your own shared-object library as well. If you do, use -Wl,--library-path,. so that ld can find your library in the local directory.)

The actual error you receive is:

/usr/bin/ld: attempted static link of dynamic object `libnamespec.so'
collect2: error: ld returned 1 exit status

Hope that helps.

 public void paintComponent (Graphics g)
    { 
((Graphics2D) g).setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER,0.0f)); // draw transparent background
     super.paintComponent(g);
    ((Graphics2D) g).setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER,1.0f)); // turn on opacity
    g.setColor(Color.RED);
    g.fillRect(20, 20, 500, 300);
     } 

I have tried to do it this way, but it is very flickery

I would use a "wait"-command for a specific time (milliseconds) of your own choice. The application executes until the line you want to inspect and then continues after the time expired.

Include the <time.h> header:

clock_t wait;

wait = clock();
while (clock() <= (wait + 5000)) // Wait for 5 seconds and then continue
    ;
wait = 0;

Without using actions the options would be:

1. move one of the methods to a different controller, so that they don't clash.

2. use just one method that takes the param, and if it's null call the other method from your code.

For me just ${workspace} worked without even initializing the variable 'workspace.'

Most likely, you need to have the Javascript served over SSL.

Source: https://www.parse.com/questions/internet-explorer-and-the-javascript-sdk

I was facing similar problems trying to do some dat import on an intermediate schema (that later we move on to the final one). As we rely on things like extensions (for example PostGIS), the "run_insert" sql file did not fully solved the problem.

After a while, we've found that at least with Postgres 9.3 the solution is far easier... just create your SQL script always specifying the schema when refering to the table:

CREATE TABLE "my_schema"."my_table" (...); COPY "my_schema"."my_table" (...) FROM stdin;

This way using psql -f xxxxx works perfectly, and you don't need to change search_paths nor use intermediate files (and won't hit extension schema problems).

All you need to do is to replace 'import android.support.annotation.Nullable' in class imports to 'import androidx.annotation.Nullable;'

Thats a common practice..whenever any import giving issue...remove that import and simply press Alt+Enter on the related class..that will give you option to 'import class'..hint Enter and things will get resolved...

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

I think it is enough:

list.Select(s => s.MyField).Distinct();

Try setting host=127.0.0.1 on your db settings file, it worked for me! :)

Hope it helps!

Somehow my project was set to compile as a Static Library (.lib). After changing this to a Dynamic Library (.dll), tests where discovered correctly by Visual Studio 2012.

For me, this ended up being because I had the wrong SDK level installed (new version of Android Studio installed the SDK for Android 10, whereas I have a device that runs only Android 8.1). While Android Studio would "recognize" the device and display a string in the "devices" menu instead of just saying that no device was connected, installing the right SDK level for my device ended up changing the string to something recognizable (my device's model name) and allowed me to actually run my app over ADB.

The else clause is only executed when the while-condition becomes false.

Here are some examples:

Example 1: Initially the condition is false, so else-clause is executed.

i = 99999999

while i < 5:
    print(i)
    i += 1
else:
    print('this')

OUTPUT:

this

Example 2: The while-condition i < 5 never became false because i == 3 breaks the loop, so else-clause was not executed.

i = 0

while i < 5:
    print(i)
    if i == 3:
        break
    i += 1
else:
    print('this')

OUTPUT:

0
1
2
3

Example 3: The while-condition i < 5 became false when i was 5, so else-clause was executed.

i = 0

while i < 5:
    print(i)
    i += 1
else:
    print('this')

OUTPUT:

0

surely you can do this with worksheet formulas, avoiding VBA entirely:

so for this value in say, column AV S:1 P:0 K:1 Q:1

you put this formula in column BC:

=MID(AV:AV,FIND("S",AV:AV)+2,1)

then these formulas in columns BD, BE...

=MID(AV:AV,FIND("P",AV:AV)+2,1)
=MID(AV:AV,FIND("K",AV:AV)+2,1)
=MID(AV:AV,FIND("Q",AV:AV)+2,1)

so these formulas look for the values S:1, P:1 etc in column AV. If the FIND function returns an error, then 0 is returned by the formula, else 1 (like an IF, THEN, ELSE

Then you would just copy down the formulas for all the rows in column AV.

since python 3.5 you can use * iterable unpacking operator:

user_list = [*your_iterator]

but the pythonic way to do it is:

user_list  = list(your_iterator)

Even though you see the time in HH:MM AM/PM format, on the backend it still works in 24 hour format, you can try using some basic javascript to see that.

I assume the question is already answered. If above solution doesn't help in solving the issue then can use below to solve the issue.

The issue occurs if sometimes your maven user settings is not reflecting correct settings.xml file.

To update the settings file go to Windows > Preferences > Maven > User Settings and update the settings.xml to it correct location.

Once this is doen re-build the project, these should solve the issue. Thanks.

For Android API level 13 and you need to use this:

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

Then (0,0) is top left corner and (maxX,maxY) is bottom right corner of the screen.

The 'getWidth()' for screen size is deprecated since API 13

Furthermore getwidth() and getHeight() are methods of android.view.View class in android.So when your java class extends View class there is no windowManager overheads.

          int maxX=getwidht();
          int maxY=getHeight();

as simple as that.

Actually, it doesn't really work. You can find an explanation in one of the comments in the manual page: http://www.php.net/manual/en/features.file-upload.php#74692

Answer to updated question: the obvious difference is that server-side checks are reliable, client-side checks are not.

You can use the Search & Replace feature with this regex ^([\w\d\_\.\s\-]*)$ to find text and the replaced text is "$1".

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

I'm using Batik for this. The complete Delphi code:

procedure ExecNewProcess(ProgramName : String; Wait: Boolean);
var
  StartInfo : TStartupInfo;
  ProcInfo : TProcessInformation;
  CreateOK : Boolean;
begin
  FillChar(StartInfo, SizeOf(TStartupInfo), #0);
  FillChar(ProcInfo, SizeOf(TProcessInformation), #0);
  StartInfo.cb := SizeOf(TStartupInfo);
  CreateOK := CreateProcess(nil, PChar(ProgramName), nil, nil, False,
              CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS,
              nil, nil, StartInfo, ProcInfo);
  if CreateOK then begin
    //may or may not be needed. Usually wait for child processes
    if Wait then
      WaitForSingleObject(ProcInfo.hProcess, INFINITE);
  end else
    ShowMessage('Unable to run ' + ProgramName);

  CloseHandle(ProcInfo.hProcess);
  CloseHandle(ProcInfo.hThread);
end;

procedure ConvertSVGtoPNG(aFilename: String);
const
  ExecLine = 'c:\windows\system32\java.exe -jar C:\Apps\batik-1.7\batik-rasterizer.jar ';
begin
  ExecNewProcess(ExecLine + aFilename, True);
end;

for (int i=0; i<dt_pattern.Rows.Count; i++)
{
    DataRow dr = dt_pattern.Rows[i];
}

In the loop, you can now reference row i+1 (assuming there is an i+1)

To click() on the element with text as App Configuration you can use either of the following Locator Strategies:

• linkText:

  driver.findElement(By.linkText("App Configuration")).click();
  

• cssSelector:

  driver.findElement(By.cssSelector("a[href='/docs/configuration']")).click();
  

• xpath:

  driver.findElement(By.xpath("//a[@href='/docs/configuration' and text()='App Configuration']")).click();
  

Ideally, to click() on the element you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies:

• linkText:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.linkText("App Configuration"))).click();
  

• cssSelector:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("a[href='/docs/configuration']"))).click();
  

• xpath:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[@href='/docs/configuration' and text()='App Configuration']"))).click();

Follow these steps:

1. Open Netbeans
2. Click File > New Project > JavaFX > JavaFX with existing sources
3. Click Next
4. Name the project
5. Click Next
6. Under Source Package Folders click Add Folder
7. Select the nbproject folder under the zip file you wish to upload (Note: you need to unzip the folder)
8. Click Next
9. All the files will be included but you can exclude some if you wish
10. Click Finish and the project should be there

If you don't have the source folder added do the following

1. Under your projects directory tree right click on Source Packages
2. Click New
3. Click Java Package and name it with the name of the package the source files have
4. Go to the directory location (i.e., using Windows Explorer not Netbeans) of those source files, highlight them all, then drag and drop them under that Java Package you just created
5. Click Run
6. Click Clean and Build Project

Now you can have fun and run the application.

I created different versions of how to reverse a string in python in my repo: https://github.com/fedmich/Python-Codes/tree/master/Reverse%20a%20String

You can do it by using list-comprehension or lambda technique:

# Reverse a string without using reverse() function
s = 'Federico';
li = list( s )  #convert string to list

ret = [ li[i-1] for i in xrange(len(li),0,-1)  ]    #1 liner lambda
print ( "".join( ret ) )

or by doing a backward for loop

# Reverse a string without using reverse() function
s = 'Federico';
r = []

length = len(s)
for i in xrange(length,0,-1):
    r.append( s[ i - 1] )

print ( "".join(r) )

Not possible. The background will always be as large as it can be, but you can stop it from repeating itself with background-repeat.

background-repeat: no-repeat;

Secondly, the background does not go into margin-area of a box, so if you want to have the background only be on the actual contents of a box, you can use margin instead of padding.

Thirdly, you can control where the background image starts. By default it's the top left corner of a box, but you can control that with background-position, like this:

background-position: center top;

or perhaps

background-position: 20px -14px;

Negative positioning is used a lot with CSS sprites.

you can use

int[] a = new int[]{1,2,3,4,5};
int[] b = a.clone();

as well.

If the error message only occurs locally, try opening the sql file and press the play button.

Looking again at your question, I think I see what's wrong with your conf file. You set:

fullresolution=1366x768 windowresolution=1366x768

That's why you're getting the letterboxing (black on either side). You've essentially told Dosbox that your screen is the same size as your window, but your screen is actually bigger, 1600x900 (or higher) per the Googled specs for that computer. So the 'difference' shows up in black. So you either should change fullresolution to your actual screen resolution, or revert to fullresolution=original default, and only specify the window resolution.

So now I wonder if you really want fullscreen, though your question asks about only a window. For you are getting a window, but you sized it short of your screen, hence the two black stripes (letterboxing). If you really want fullscreen, then you need to specify the actual resolution of your screen. 1366x768 is not big enough.

The next issue is, what's the resolution of the program itself? It won't go past its own resolution. So if the program/game is (natively) say 1280x720 (HD), then your window resolution setting shouldn't be bigger than that (remember, it's fixed not dynamic when you use AxB as windowresolution).

Example: DOS Lotus 123 will only extend eight columns and 20 rows. The bigger the Dosbox, the bigger the text, but not more columns and rows. So setting a higher windowresolution for that, only results in bigger text, not more columns and rows. After that you'll have letterboxing.

Hope this helps you better.

You can do something like

@NamedQuery(name="IssueDescriptor.findByIssueDescriptorId" ,

    query=" select new com.test.live.dto.IssuesDto (idc.id, dep.department, iss.issueName, 
               cat.issueCategory, idc.issueDescriptor, idc.description) 
            from Department dep 
            inner join dep.issues iss 
            inner join iss.category cat 
            inner join cat.issueDescriptor idc 
            where idc.id in(?1)")

And there must be Constructor like

public IssuesDto(long id, String department, String issueName, String issueCategory, String issueDescriptor,
            String description) {
        super();
        this.id = id;
        this.department = department;
        this.issueName = issueName;
        this.issueCategory = issueCategory;
        this.issueDescriptor = issueDescriptor;
        this.description = description;
    }

i believe this jquery work for you well please check a code below.

this will make your submit action works and open a link in new tab whether you want to open action url again or a new link

jQuery('form').on('submit',function(e){
setTimeout(function () { window.open('https://www.google.com','_blank');}, 1000);});})

This code works for me perfect..

Once you have add your layout with at least one widget in it, select your window and click the "Update" button of QtDesigner. The interface will be resized at the most optimized size and your layout will fit the whole window. Then when resizing the window, the layout will be resized in the same way.

You can't put a CLOB in the WHERE clause. From the documentation:

Large objects (LOBs) are not supported in comparison conditions. However, you can use PL/SQL programs for comparisons on CLOB data.

If your values are always less than 4k, you can use:

UPDATE IMS_TEST 
   SET TEST_Category           = 'just testing'  
 WHERE to_char(TEST_SCRIPT)    = 'something'
   AND ID                      = '10000239';

It is strange to search by a CLOB anyways.. could you not just search by the ID column?

Seen a lot of the answers, but the correct one is to provide the full options for the header function call as per the php manual

void header ( string $string [, bool $replace = true [, int $http_response_code ]] )

If you invoke with

header('HTTP/1.0 403 Forbidden', true, 403);

the normal behavior of HTTP 403 as configured with Apache or any other server would follow.

I also had your problem,and I solved the problem using the following steps (though you may already finish the problem, it just shares for anyone who visit this page):

1. Unplug your Arduino
2. Prepare an empty setup and empty loop program
3. Write a comment symbol '//' at the end of program
4. Set your keyboard pointer next to the '//'symbol
5. Plug your Arduino into the computer, wait until the Arduino is completely bootloaded and it will output 'Hello, World!'
6. You will see the 'Hello, World!' outputting script will be shown as comment, so you can click Upload safely.

You can check SelectedIndex or SelectedValue or SelectedItem property in the SelectionChanged event of the Combobox control.

If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:

which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment

Or, (at least on OSX using brew):

mkvirtualenv --python=`which python3` nameOfEnvironment

Start using the environment and you'll see that as soon as you type python you'll start using python3

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

Obviously it has been some years this post has been alive - but the fact is I did find it when looking for a similar issue. In our case, we had to add the username / password info to the Security header. This is different from adding header info outside of the Security headers.

The correct way to do this (for custom bindings / authenticationMode="CertificateOverTransport") (as on the .Net framework version 4.6.1), is to add the Client Credentials as usual :

    client.ClientCredentials.UserName.UserName = "[username]";
    client.ClientCredentials.UserName.Password = "[password]";

and then add a "token" in the security binding element - as the username / pwd credentials would not be included by default when the authentication mode is set to certificate.

You can set this token like so:

    //Get the current binding 
    System.ServiceModel.Channels.Binding binding = client.Endpoint.Binding;
    //Get the binding elements 
    BindingElementCollection elements = binding.CreateBindingElements();
    //Locate the Security binding element
    SecurityBindingElement security = elements.Find<SecurityBindingElement>();

    //This should not be null - as we are using Certificate authentication anyway
    if (security != null)
    {
    UserNameSecurityTokenParameters uTokenParams = new UserNameSecurityTokenParameters();
    uTokenParams.InclusionMode = SecurityTokenInclusionMode.AlwaysToRecipient;
security.EndpointSupportingTokenParameters.SignedEncrypted.Add(uTokenParams);
    }

   client.Endpoint.Binding = new CustomBinding(elements.ToArray());

That should do it. Without the above code (to explicitly add the username token), even setting the username info in the client credentials may not result in those credentials passed to the Service.

I saw some answers at this post and it's possible to be considered completed base knowledge, because have a several approaches in C# Programming to resolve the same problem. Only one thing that is necessary to be considered is about a difference between Pure UTF-8 and UTF-8 with B.O.M..

In last week, at my job, I need to develop one functionality that outputs CSV files with B.O.M. and other CSVs with pure UTF-8 (without B.O.M.), each CSV file Encoding type will be consumed by different non-standardized APIs, that one API read UTF-8 with B.O.M. and the other API read without B.O.M.. I need to research the references about this concept, reading "What's the difference between UTF-8 and UTF-8 without B.O.M.?" Stack Overflow discussion and this Wikipedia link "Byte order mark" to build my approach.

Finally, my C# Programming for the both UTF-8 encoding types (with B.O.M. and pure) needed to be similar like this example bellow:

//for UTF-8 with B.O.M., equals shared by Zanoni (at top)
string result = System.Text.Encoding.UTF8.GetString(byteArray);

//for Pure UTF-8 (without B.O.M.)
string result = (new UTF8Encoding(false)).GetString(byteArray);

There are tons of sample code online as to how to do this.

Here is just one example of how to do this: http://geekswithblogs.net/dotNETvinz/archive/2009/04/30/creating-a-simple-registration-form-in-asp.net.aspx

you define the text boxes between the following tag:

<form id="form1" runat="server"> 

you create your textboxes and define them to runat="server" like so:

<asp:TextBox ID="TxtName" runat="server"></asp:TextBox>

define a button to process your logic like so (notice the onclick):

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

in the code behind, you define what you want the server to do if the user clicks on the button by defining a method named

protected void Button1_Click(object sender, EventArgs e)

or you could just double click the button in the design view.

Here is a very quick sample of code to insert into a table in the button click event (codebehind)

protected void Button1_Click(object sender, EventArgs e)
{
   string name = TxtName.Text; // Scrub user data

   string connString = ConfigurationManager.ConnectionStrings["yourconnstringInWebConfig"].ConnectionString;
   SqlConnection conn = null;
   try
   {
          conn = new SqlConnection(connString);
          conn.Open();

          using(SqlCommand cmd = new SqlCommand())
          {
                 cmd.Conn = conn;
                 cmd.CommandType = CommandType.Text;
                 cmd.CommandText = "INSERT INTO dummyTable(name) Values (@var)";
                 cmd.Parameters.AddWithValue("@var", name);
                 int rowsAffected = cmd.ExecuteNonQuery();
                 if(rowsAffected ==1)
                 {
                        //Success notification
                 }
                 else
                 {
                        //Error notification
                 }
          }
   }
   catch(Exception ex)
   {
          //log error 
          //display friendly error to user
   }
   finally
   {
          if(conn!=null)
          {
                 //cleanup connection i.e close 
          }
   }
}

had this problem as output from Azure DevOps after setting to build the .csproj instead of the .sln in the Build Pipeline.

The solution for me: Edit .csproj of the affected project, then copy your whole

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCpu' ">

Node, paste it, and then change the first line as followed:

    <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|any cpu' ">

The reason is, that in my case the error said

Please check to make sure that you have specified a valid combination of Configuration and Platform for this project.  Configuration='release'  Platform='any cpu'.  

Why Azure wants to use "any cpu" instead of the default "AnyCpu" is a mystery for me, but this hack works.

With template literals, you can use multiple spaces or multi-line strings and string interpolation. Template Literals are a new ES2015 / ES6 feature that allows you to work with strings. The syntax is very simple, just use backticks instead of single or double quotes:

let a = `something                 something`;

and to make multiline strings just press enter to create a new line, with no special characters:

let a = `something 

    
                         something`;

The results are exactly the same as you write in the string.

1.in your main controllview :

 if let filePath = Bundle.main.path(forResource: "clip", ofType: "mp4") {
            let fileURL = NSURL(fileURLWithPath: filePath)
            videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)

3. and a PlayerView class to create a videoview:

   override class var layerClass: AnyClass {
       get {
         return AVPlayerLayer.self
       }
   }
   
   
   var player:AVPlayer? {
       set {
           if let layer = layer as? AVPlayerLayer {
               layer.player = player
           }
       }
       get {
           if let layer = layer as? AVPlayerLayer {
               return layer.player
           } else {
               return nil
           }
       }
   }
   }
   

Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:

app.get('/*', function(clientRequest, clientResponse) {
  var options = { 
    hostname: 'google.com',
    port: 80, 
    path: clientRequest.url,
    method: 'GET'
  };  

  var googleRequest = http.request(options, function(googleResponse) { 
    var body = ''; 

    if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
      googleResponse.on('data', function(chunk) {
        body += chunk;
      }); 

      googleResponse.on('end', function() {
        // Make changes to HTML files when they're done being read.
        body = body.replace(/google.com/gi, host + ':' + port);
        body = body.replace(
          /<\/body>/, 
          '<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
        );

        clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
        clientResponse.end(body);
      }); 
    }   
    else {
      googleResponse.pipe(clientResponse, {
        end: true
      }); 
    }

Like others mentioned you cannot delete current branch in which you are working.

In my case, I have selected "Test_Branch" in Visual Studio and was trying to delete "Test_Branch" from Sourcetree (Git GUI). And was getting below error message.

Cannot delete branch 'Test_Branch' checked out at '[directory location]'.

Switched to different branch in Visual Studio and was able to delete "Test_Branch" from Sourcetree.

I hope this helps someone who is using Visual Studio & Sourcetree.

"Access violation reading location 0x00000000" means that you're derefrencing a pointer that hasn't been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0 and so you try to read from the memory address 0x0, which the operating system detects and prevents you from doing.

Check and make sure that the array invaders[] is what you think it should be.

Also, you don't seem to be updating i ever - meaning that you keep placing the same Invader object into location 0 of invaders[] at every loop iteration.

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

try {
} catch (javax.script.ScriptException ex) {
// System.out.println(ex.getMessage());
}

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

this fails:

 DECLARE @vPortalUID NVARCHAR(32)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

 DECLARE @vPortalUID NVARCHAR(36)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
 PRINT @nPortalUID

the difference is NVARCHAR(36), your input parameter is too small!

For unmanaged types aka value types, structs:

        Marshal.SizeOf(object);

For managed objects the closer i got is an approximation.

        long start_mem = GC.GetTotalMemory(true);

        aclass[] array = new aclass[1000000];
        for (int n = 0; n < 1000000; n++)
            array[n] = new aclass();

        double used_mem_median = (GC.GetTotalMemory(false) - start_mem)/1000000D;

Do not use serialization.A binary formatter adds headers, so you can change your class and load an old serialized file into the modified class.

Also it won't tell you the real size in memory nor will take into account memory alignment.

[Edit] By using BiteConverter.GetBytes(prop-value) recursivelly on every property of your class you would get the contents in bytes, that doesn't count the weight of the class or references but is much closer to reality. I would recommend to use a byte array for data and an unmanaged proxy class to access values using pointer casting if size matters, note that would be non-aligned memory so on old computers is gonna be slow but HUGE datasets on MODERN RAM is gonna be considerably faster, as minimizing the size to read from RAM is gonna be a bigger impact than unaligned.

Try

Date.ParseExact("9/1/2009", "M/d/yyyy", new CultureInfo("en-US"))

Use the SQLCMD utility.

http://technet.microsoft.com/en-us/library/ms162773.aspx

There is a connect statement that allows you to swing from database server A to server B in the same batch.

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]] Connects to an instance of SQL Server. Also closes the current connection.

On the other hand, if you are familiar with PowerShell, you can programmatic do the same.

Your question doesn't have anything to do with PHP... just CSS.

Your CSS is correct, but your browser won't typically be able to open what you have put in for a URL. At a minimum, you'll need a file: path. It would be best to reference the file by its relative path.

I encountered today quite a similar problem : mysqldump dumped my utf-8 base encoding utf-8 diacritic characters as two latin1 characters, although the file itself is regular utf8.

For example : "é" was encoded as two characters "é". These two characters correspond to the utf8 two bytes encoding of the letter but it should be interpreted as a single character.

To solve the problem and correctly import the database on another server, I had to convert the file using the ftfy (stands for "Fixes Text For You). (https://github.com/LuminosoInsight/python-ftfy) python library. The library does exactly what I expect : transform bad encoded utf-8 to correctly encoded utf-8.

For example : This latin1 combination "é" is turned into an "é".

ftfy comes with a command line script but it transforms the file so it can not be imported back into mysql.

I wrote a python3 script to do the trick :

#!/usr/bin/python3
# coding: utf-8

import ftfy

# Set input_file
input_file = open('mysql.utf8.bad.dump', 'r', encoding="utf-8")
# Set output file
output_file = open ('mysql.utf8.good.dump', 'w')

# Create fixed output stream
stream = ftfy.fix_file(
    input_file,
    encoding=None,
    fix_entities='auto', 
    remove_terminal_escapes=False, 
    fix_encoding=True, 
    fix_latin_ligatures=False, 
    fix_character_width=False, 
    uncurl_quotes=False, 
    fix_line_breaks=False, 
    fix_surrogates=False, 
    remove_control_chars=False, 
    remove_bom=False, 
    normalization='NFC'
)

# Save stream to output file
stream_iterator = iter(stream)
while stream_iterator:
    try:
        line = next(stream_iterator)
        output_file.write(line)
    except StopIteration:
        break

So I had a similar situation with the same error. I forgot I changed the compatibility mode on my dev machine and I had a console.log command in my javascript as well. I changed compatibility mode back in IE, and removed the console.log command. No more issue.

You should take a look at the new Spatial data-types that were introduced in SQL Server 2008. They are specifically designed this kind of task and make indexing and querying the data much easier and more efficient.

http://msdn.microsoft.com/en-us/library/bb933876(v=sql.105).aspx

The number of rows is not huge... Create an index on account_import_id if its not the primary key.

CREATE INDEX idx_customer_account_import_id ON customer (account_import_id);

With introduction of Java 1.8, streams are very useful in solving this kind of problems:

Comparator <DateTime> myComparator = (arg1, arg2) 
                -> {
                    if(arg1.lt(arg2)) 
                       return -1;
                    else if (arg1.lteq(arg2))
                       return 0;
                    else
                       return 1;
                   };

ArrayList<DateTime> sortedList = myList
                   .stream()
                   .sorted(myComparator)
                   .collect(Collectors.toCollection(ArrayList::new));

CharSequence is an interface and String is its one of the implementations other than StringBuilder, StringBuffer and many other.

So, just as you use InterfaceName i = new ItsImplementation(), you can use CharSequence cs = new String("string") or simply CharSequence cs = "string";

yes block are the most used functionality , so in order to avoid the retain cycle we should avoid using the strong variable,including self inside the block, inspite use the _weak or weakself.

Please notice the function set.update(). The documentation says:

Update a set with the union of itself and others.

One of the answers in this question might help you. There seems to be a platform agnostic version for python, but I haven't tried it yet.

Try this. For python 2.7.12 we need to define constructor or need to add self to each methods followed by defining an instance of an class called object.

import cv2

class calculator:

#   def __init__(self):

def multiply(self, a, b):
    x= a*b
    print(x)

def subtract(self, a,b):
    x = a-b
    print(x)

def add(self, a,b):
    x = a+b
    print(x)

def div(self, a,b):
    x = a/b
    print(x)

 calc = calculator()
 calc.multiply(2,3)
 calc.add(2,3)
 calc.div(10,5)
 calc.subtract(2,3)

Here is a PURE CSS solution! It is Javascript-free! This one does not attempt to hide then recreate the original control, either, like the other posts here do. It uses plain CSS without any circus tricks to style the original file upload form control for all the major browsers.

This is what the file upload control looks like in Firefox, Chrome, and Edge using the CSS below. This is a very simple clean design. You can change it to look any way you like:

Internet Explorer gives you limited design control but at least you can manipulate the button using this CSS:

input[type="file"],
input[type="file"]:visited,
input[type="file"]:hover,
input[type="file"]:focus,
input[type="file"]:active {
    margin:0;
    padding: 0em 0em;
    padding: 0rem 0rem;
    overflow: hidden; /* long file names overflow so just hide the end */
    background: #ffffff;
    border-radius: .2em;
    border-radius: .2rem;
    outline: none;
    border: 2px solid #bbb;
    cursor: pointer;
    -webkit-appearance: textfield;
    -moz-appearance: textfield;
}

input[type="file"]:hover {
    background: #f9f9ff; /* I am using a light blue to indicate an interaction */
    border: 2px solid #999;
}

input[type="file"]:visited,
input[type="file"]:focus,
input[type="file"]:active {
    background: #fff; /* Default back to white when focused. */
    border: 2px solid #999;
}

/* Note: Firefox flags the file name box as a *readonly* input. So that attribute selector was added below. Note: These selectors blow up in IE so have to be separated from the same styles above. */
input[type="file"]:disabled,
input[type="file"]:read-only {
    margin: 0;
    padding: 0em 0em;
    padding: 0rem 0rem;
    overflow: hidden; /* long file names overflow so just hide the end */
    background: #ffffff;
    border-radius: .2em;
    border-radius: .2rem;
    outline: none;
    border: 2px solid #bbb;
    cursor: pointer;
    -webkit-appearance: textfield;

}

input[type="file"]:disabled:hover,
input[type="file"]:read-only:hover {
    background: #f9f9ff; /* I am using a light blue to indicate an interaction */
    border: 2px solid #999;
}

input[type="file"]:disabled:visited,
input[type="file"]:disabled:focus,
input[type="file"]:disabled:active,
input[type="file"]:read-only:visited,
input[type="file"]:read-only:focus,
input[type="file"]:read-only:active {
    background: #fff; /* Default back to white when focused. */
    border: 2px solid #999;
}

/* IE UPLOAD BUTTON STYLE: This attempts to alter the file upload button style in IE.  Keep in mind IE gives you limited design control but at least you can customize its upload button.*/

    display: inline-block;
    margin: 0;
    padding: .2em .5em;
    padding: .2rem .5rem;
    text-align: center;
    outline: none;
    border: none;
    background: #fff;
    white-space: nowrap;
    cursor: pointer;
}
/* FIREFOX UPLOAD BUTTON STYLE */
::file-selector-button {/* firefox */
    display: inline-block;

/* CHROME AND EDGE UPLOAD BUTTON STYLE */
::-webkit-file-upload-button { /* chrome and edge */

    padding: .19rem .5rem;
    -webkit-appearance: button;

    border: none;
    border-right: 2px solid #bbb;
    background: #eee;
    white-space: nowrap;
    cursor: pointer;
}

Note: You might test it in older versions of Firefox, Chrome, Edge, and IE.

I need to do the same thing. I ended up with something similar to Kman

       static void ExcelToCSVCoversion(string sourceFile,  string targetFile)
    {
        Application rawData = new Application();

        try
        {
            Workbook workbook = rawData.Workbooks.Open(sourceFile);
            Worksheet ws = (Worksheet) workbook.Sheets[1];
            ws.SaveAs(targetFile, XlFileFormat.xlCSV);
            Marshal.ReleaseComObject(ws);
        }

        finally
        {
            rawData.DisplayAlerts = false;
            rawData.Quit();
            Marshal.ReleaseComObject(rawData);
        }


        Console.WriteLine();
        Console.WriteLine($"The excel file {sourceFile} has been converted into {targetFile} (CSV format).");
        Console.WriteLine();
    }

If there are multiple sheets this is lost in the conversion but you could loop over the number of sheets and save each one as csv.

It's also useful for splitting ranges; range(a,b) can be split into range(a, x) and range(x, b), whereas with inclusive range you would write either x-1 or x+1. While you rarely need to split ranges, you do tend to split lists quite often, which is one of the reasons slicing a list l[a:b] includes the a-th element but not the b-th. Then range having the same property makes it nicely consistent.

Here is a simple code for javascript validation, and after it validates it will clean the input file.

<input type="file" id="image" accept="image/*" onChange="validate(this.value)"/>

function validate(file) {
    var ext = file.split(".");
    ext = ext[ext.length-1].toLowerCase();      
    var arrayExtensions = ["jpg" , "jpeg", "png", "bmp", "gif"];

    if (arrayExtensions.lastIndexOf(ext) == -1) {
        alert("Wrong extension type.");
        $("#image").val("");
    }
}

For anybody else looking, here is a decent set of steps. http://forums.asp.net/t/1678976.aspx/1

For me the first answer appears a bit confusing, so to make it short and clean:

npm install <package_name> saves any specified packages into dependencies by default. Additionally, you can control where and how they get saved with some additional flags:

npm install <package_name> --no-save Prevents saving to dependencies.

npm install <package_name> ---save-dev updates the devDependencies in your package. These are only used for local testing and development.

iPad Detection

You should be able to detect an iPad user by taking a look at the userAgent property:

var is_iPad = navigator.userAgent.match(/iPad/i) != null;

iPhone/iPod Detection

Similarly, the platform property to check for devices like iPhones or iPods:

function is_iPhone_or_iPod(){
     return navigator.platform.match(/i(Phone|Pod))/i)
}

Notes

While it works, you should generally avoid performing browser-specific detection as it can often be unreliable (and can be spoofed). It's preferred to use actual feature-detection in most cases, which can be done through a library like Modernizr.

As pointed out in Brennen's answer, issues can arise when performing this detection within the Facebook app. Please see his answer for handling this scenario.

The following will work independent of your database privileges:

select * from all_triggers
where table_name = 'YOUR_TABLE'

The following alternate options may or may not work depending on your assigned database privileges:

select * from DBA_TRIGGERS

or

select * from USER_TRIGGERS

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

I took a look at the datejs and stripped out the code necessary to add months to a date handling edge cases (leap year, shorter months, etc):

Date.isLeapYear = function (year) { 
    return (((year % 4 === 0) && (year % 100 !== 0)) || (year % 400 === 0)); 
};

Date.getDaysInMonth = function (year, month) {
    return [31, (Date.isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
};

Date.prototype.isLeapYear = function () { 
    return Date.isLeapYear(this.getFullYear()); 
};

Date.prototype.getDaysInMonth = function () { 
    return Date.getDaysInMonth(this.getFullYear(), this.getMonth());
};

Date.prototype.addMonths = function (value) {
    var n = this.getDate();
    this.setDate(1);
    this.setMonth(this.getMonth() + value);
    this.setDate(Math.min(n, this.getDaysInMonth()));
    return this;
};

This will add "addMonths()" function to any javascript date object that should handle edge cases. Thanks to Coolite Inc!

Use:

var myDate = new Date("01/31/2012");
var result1 = myDate.addMonths(1);

var myDate2 = new Date("01/31/2011");
var result2 = myDate2.addMonths(1);

->> newDate.addMonths -> mydate.addMonths

result1 = "Feb 29 2012"

result2 = "Feb 28 2011"

Per Mozilla's Map documentation, you can initialize as follows:

    ]);

The key here is to visualise the call tree. Once done that, the complexity is:

nodes of the call tree * complexity of other code in the function

the latter term can be computed the same way we do for a normal iterative function.

Instead, the total nodes of a complete tree are computed as

                  C^L - 1
                  -------  , when C>1
               /   C - 1
              /
 # of nodes =
              \    
               \ 
                  L        , when C=1

Where C is number of children of each node and L is the number of levels of the tree (root included).

It is easy to visualise the tree. Start from the first call (root node) then draw a number of children same as the number of recursive calls in the function. It is also useful to write the parameter passed to the sub-call as "value of the node".

So, in the examples above:

1. the call tree here is C = 1, L = n+1. Complexity of the rest of function is O(1). Therefore total complexity is L * O(1) = (n+1) * O(1) = O(n)

n     level 1
n-1   level 2
n-2   level 3
n-3   level 4
... ~ n levels -> L = n

2. call tree here is C = 1, L = n/5. Complexity of the rest of function is O(1). Therefore total complexity is L * O(1) = (n/5) * O(1) = O(n)

n
n-5
n-10
n-15
... ~ n/5 levels -> L = n/5

3. call tree here is C = 1, L = log(n). Complexity of the rest of function is O(1). Therefore total complexity is L * O(1) = log5(n) * O(1) = O(log(n))

n
n/5
n/5^2
n/5^3
... ~ log5(n) levels -> L = log5(n)

4. call tree here is C = 2, L = n. Complexity of the rest of function is O(1). This time we use the full formula for the number of nodes in the call tree because C > 1. Therefore total complexity is (C^L-1)/(C-1) * O(1) = (2^n - 1) * O(1) = O(2^n).

               n                   level 1
      n-1             n-1          level 2
  n-2     n-2     n-2     n-2      ...
n-3 n-3 n-3 n-3 n-3 n-3 n-3 n-3    ...     
              ...                ~ n levels -> L = n

5. call tree here is C = 1, L = n/5. Complexity of the rest of function is O(n). Therefore total complexity is L * O(1) = (n/5) * O(n) = O(n^2)

n
n-5
n-10
n-15
... ~ n/5 levels -> L = n/5

To find which field has invalid characters:

SELECT * FROM Staging.APARMRE1 FOR XML AUTO, TYPE

You can test it with this query:

SELECT top 1 'char 31: '+char(31)+' (hex 0x1F)' field
from sysobjects
FOR XML AUTO, TYPE

The result will be:

Msg 6841, Level 16, State 1, Line 3 FOR XML could not serialize the data for node 'field' because it contains a character (0x001F) which is not allowed in XML. To retrieve this data using FOR XML, convert it to binary, varbinary or image data type and use the BINARY BASE64 directive.

It is very useful when you write xml files and get error of invalid characters when validate it.

I think traits are useful to create classes that contain methods that can be used as methods of several different classes.

For example:

trait ToolKit
{
    public $errors = array();

    public function error($msg)
    {
        $this->errors[] = $msg;
        return false;
    }
}

You can have and use this "error" method in any class that uses this trait.

class Something
{
    use Toolkit;

    public function do_something($zipcode)
    {
        if (preg_match('/^[0-9]{5}$/', $zipcode) !== 1)
            return $this->error('Invalid zipcode.');
        
        // do something here
    }
}

While with interfaces you can only declare the method signature, but not its functions' code. Also, to use an interface you need to follow a hierarchy, using implements. This is not the case with traits.

It is completely different!

Instead of override you can add another class to the element and then you have an extra abilities. for example:

HTML

<div class="style1 style2"></div>

CSS

//only style for the first stylesheet
.style1 {
   width: 100%;      
}
//only style for second stylesheet
.style2 {
   width: 50%;     
}
//override all
.style1.style2 { 
   width: 70%;
}

Warning. I used setAllowsRubberBanding: in my app, and Apple rejected it, stating that non-public API functions are not allowed (cite: 3.3.1)

So I did some tests with sqlite for very large files, and came to some conclusions (at least for my specific application).

The tests involve a single sqlite file with either a single table, or multiple tables. Each table had about 8 columns, almost all integers, and 4 indices.

The idea was to insert enough data until sqlite files were about 50GB.

Single Table

I tried to insert multiple rows into a sqlite file with just one table. When the file was about 7GB (sorry I can't be specific about row counts) insertions were taking far too long. I had estimated that my test to insert all my data would take 24 hours or so, but it did not complete even after 48 hours.

This leads me to conclude that a single, very large sqlite table will have issues with insertions, and probably other operations as well.

I guess this is no surprise, as the table gets larger, inserting and updating all the indices take longer.

Multiple Tables

I then tried splitting the data by time over several tables, one table per day. The data for the original 1 table was split to ~700 tables.

This setup had no problems with the insertion, it did not take longer as time progressed, since a new table was created for every day.

Vacuum Issues

As pointed out by i_like_caffeine, the VACUUM command is a problem the larger the sqlite file is. As more inserts/deletes are done, the fragmentation of the file on disk will get worse, so the goal is to periodically VACUUM to optimize the file and recover file space.

However, as pointed out by documentation, a full copy of the database is made to do a vacuum, taking a very long time to complete. So, the smaller the database, the faster this operation will finish.

Conclusions

For my specific application, I'll probably be splitting out data over several db files, one per day, to get the best of both vacuum performance and insertion/delete speed.

This complicates queries, but for me, it's a worthwhile tradeoff to be able to index this much data. An additional advantage is that I can just delete a whole db file to drop a day's worth of data (a common operation for my application).

I'd probably have to monitor table size per file as well to see when the speed will become a problem.

It's too bad that there doesn't seem to be an incremental vacuum method other than auto vacuum. I can't use it because my goal for vacuum is to defragment the file (file space isn't a big deal), which auto vacuum does not do. In fact, documentation states it may make fragmentation worse, so I have to resort to periodically doing a full vacuum on the file.

Use ng-value for set value of input box after clicking on a button:

"input type="email"  class="form-control" id="email2" ng-value="myForm.email2" placeholder="Email"

and

Set Value as:

 $scope.myForm.email2 = $scope.names[0].success;

The latest version of XMLUnit can help the job of asserting two XML are equal. Also XMLUnit.setIgnoreWhitespace() and XMLUnit.setIgnoreAttributeOrder() may be necessary to the case in question.

See working code of a simple example of XML Unit use below.

import org.custommonkey.xmlunit.DetailedDiff;
import org.custommonkey.xmlunit.XMLUnit;
import org.junit.Assert;

public class TestXml {

    public static void main(String[] args) throws Exception {
        String result = "<abc             attr=\"value1\"                title=\"something\">            </abc>";
        // will be ok
        assertXMLEquals("<abc attr=\"value1\" title=\"something\"></abc>", result);
    }

    public static void assertXMLEquals(String expectedXML, String actualXML) throws Exception {
        XMLUnit.setIgnoreWhitespace(true);
        XMLUnit.setIgnoreAttributeOrder(true);

        DetailedDiff diff = new DetailedDiff(XMLUnit.compareXML(expectedXML, actualXML));

        List<?> allDifferences = diff.getAllDifferences();
        Assert.assertEquals("Differences found: "+ diff.toString(), 0, allDifferences.size());
    }

}

If using Maven, add this to your pom.xml:

<dependency>
    <groupId>xmlunit</groupId>
    <artifactId>xmlunit</artifactId>
    <version>1.4</version>
</dependency>

I found a way to change the Application Output theme and everything that can't be edited from .css.

If you use osX:

1. Navigate to your Qt install directory.
2. Right click Qt Creator application and select "Show Package Contents"
3. Copy the following file to your desktop> Contents/Resources/themes/dark.creatortheme or /default.creatortheme. Depending on if you are using dark theme or default theme.
4. Edit the file in text editor.
5. Under [Palette], there is a line that says error=ffff0000.
6. Set a new color, save, and override the original file.

This will give you exactly what you need (path does NOT have to exist for this to work)

DirectoryInfo di = new DirectoryInfo(@"C:\blah\..\bling");
string cleanPath = di.FullName;

Running the following commands solved this for me 1. python manage.py migrate 2. python manage.py makemigrations 3. python manage.py makemigrations appName
