I have recently evaluated and picked a persistence framework for a java project and my findings are as follows:

What I am seeing is that the support in favour of JDO is primarily:

• you can use non-sql datasources, db4o, hbase, ldap, bigtable, couchdb (plugins for cassandra) etc.
• you can easily switch from an sql to non-sql datasource and vice-versa.
• no proxy objects and therefore less pain with regards to hashcode() and equals() implementations
• more POJO and hence less workarounds required
• supports more relationship and field types

and the support in favour of JPA is primarily:

• more popular
• jdo is dead
• doesnt use bytecode enhancement

I am seeing a lot of pro-JPA posts from JPA developers who have clearly not used JDO/Datanucleus offering weak arguments for not using JDO.

I am also seeing a lot of posts from JDO users who have migrated to JDO and are much happier as a result.

In respect of JPA being more popular, it seems that this is due in part due to RDBMS vendor support rather than it being technically superior. (Sounds like VHS/Betamax to me).

JDO and it's reference implementation Datanucleus is clearly not dead, as shown by Google's adoption of it for GAE and active development on the source-code (http://sourceforge.net/projects/datanucleus/).

I have seen a number of complaints about JDO due to bytecode enhancement, but no explanation yet for why it is bad.

In fact, in a world that is becoming more and more obsessed by NoSQL solutions, JDO (and the datanucleus implementation) seems a much safer bet.

I have just started using JDO/Datanucleus and have it set up so that I can switch easily between using db4o and mysql. It's helpful for rapid development to use db4o and not have to worry too much about the DB schema and then, once the schema is stabilised to deploy to a database. I also feel confident that later on, I could deploy all/part of my application to GAE or take advantage of distributed storage/map-reduce a la hbase /hadoop / cassandra without too much refactoring.

I found the initial hurdle of getting started with Datanucleus a little tricky - The documentation on the datanucleus website is a little hard to get into - the tutorials are not as easily to follow as I would have liked. Having said that, the more detailed documentation on the API and mapping is very good once you get past the initial learning curve.

The answer is, it depends what you want. I would rather have cleaner code, no-vendor-lock-in, more pojo-orientated, nosql options verses more-popular.

If you want the warm fussy feeling that you are doing the same as the majority of other developers/sheep, choose JPA/hibernate. If you want to lead in your field, test drive JDO/Datanucleus and make your own mind up.

In python, not is a boolean operator which gets the opposite of a value:

>>> myval = 0
>>> nyvalue = not myval
>>> nyvalue
True
>>> myval = 1
>>> nyvalue = not myval
>>> nyvalue
False

And True == 1 and False == 0 (if you need to convert it to an integer, you can use int())

1. Install Microsoft visual c++ 14.0 build tool.(Windows 7)
2. create a virtual environment using conda.
3. Activate the environment and use conda to install the necessary package.

For example: conda install -c conda-forge spacy

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

your div looks like this:

<div class="readonly_label" id="field-function_purpose">Other</div>

With jquery you can easily get inner content:

Use .html() : HTML contents of the first element in the set of matched elements or set the HTML contents of every matched element.

var text = $('#field-function_purpose').html(); 

Read more about jquery .html()

or

Use .text() : Get the combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.

var text = $('#field-function_purpose').text();

Read more about jquery .text()

If you want "To get all tables only", Then use this query:

SELECT TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%'
and TABLE_SCHEMA = 'tresbu_lk'

If you want "To get all tables with Columns", Then use this query:

SELECT DISTINCT TABLE_NAME, COLUMN_NAME  
FROM INFORMATION_SCHEMA.COLUMNS  
WHERE column_name LIKE '%'  
AND TABLE_SCHEMA='tresbu_lk'

Because when I use one or another I get a window prompt asking me to download the file for both of them.

This behavior depends on the browser and the file you are trying to serve. With inline, the browser will try to open the file within the browser.

For example, if you have a PDF file and Firefox/Adobe Reader, an inline disposition will open the PDF within Firefox, whereas attachment will force it to download.

If you're serving a .ZIP file, browsers won't be able to display it inline, so for inline and attachment dispositions, the file will be downloaded.

I'd be careful about trying to get too clever here. I think it's confusing as it is and using more advanced nth-child parameters will only make it more complicated. As for the background color I'd just set that to a variable.

Here goes what I came up with before I realized trying to be too clever might be a bad thing.

#romtest {
 $bg: #e5e5e5;
 .detailed {
    th {
      &:nth-child(-2n+6) {
        background-color: $bg;
      }
    }
    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        background-color: $bg;
      }
      &.last {
        &:nth-child(-2n+4){
          background-color: $bg;
        }
      }
    }
  }
}

and here is a quick demo: http://codepen.io/anon/pen/BEImD

----EDIT----

Here's another approach to avoid retyping background-color:

#romtest {
  %highlight {
    background-color: #e5e5e5; 
  }
  .detailed {
    th {
      &:nth-child(-2n+6) {
        @extend %highlight;
      }
    }

    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        @extend %highlight;
      }
      &.last {
        &:nth-child(-2n+4){
          @extend %highlight;
        }
      }
    }
  }
}

Add this Annotation to Entity Class (Model) that works for me this cause lazy loading via the hibernate proxy object.

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

Apache's Multi-Processing Modules (MPMs) are responsible for binding to network ports on the machine, accepting requests, and dispatching children to handle the requests (http://httpd.apache.org/docs/2.2/mpm.html).

They're like any other Apache module, except that just one and only one MPM must be loaded into the server at any time. MPMs are chosen during configuration and compiled into the server by using the argument --with-mpm=NAME with the configure script where NAME is the name of the desired MPM.

Apache will use a default MPM for each operating system unless a different one is choosen at compile-time (for instance on Windows mpm_winnt is used by default). Here's the list of operating systems and their default MPMs:

• BeOS beos
• Netware mpm_netware
• OS/2 mpmt_os2
• Unix/Linux prefork (update for Apache version = 2.4: prefork, worker, or event, depending on platform capabilities)
• Windows mpm_winnt

To check what modules are compiled into the server use the command-line option -l (here is the documentation). For instance on a Windows installation you might get something like:

> httpd -l
Compiled in modules:
  core.c
  mod_win32.c
  mpm_winnt.c
  http_core.c
  mod_so.c

As of version 2.2 this is the list of available core features and MPM modules:

• core - Core Apache HTTP Server features that are always available
• mpm_common - A collection of directives that are implemented by more than one multi-processing module (MPM)
• beos - This Multi-Processing Module is optimized for BeOS.
• event - An experimental variant of the standard worker MPM
• mpm_netware Multi-Processing Module implementing an exclusively threaded web server optimized for Novell NetWare
• mpmt_os2 Hybrid multi-process, multi-threaded MPM for OS/2
• prefork Implements a non-threaded, pre-forking web server
• mpm_winnt - This Multi-Processing Module is optimized for Windows NT.
• worker - Multi-Processing Module implementing a hybrid multi-threaded multi-process web server

Now, to the difference between prefork and worker.

The prefork MPM

implements a non-threaded, pre-forking web server that handles requests in a manner similar to Apache 1.3. It is appropriate for sites that need to avoid threading for compatibility with non-thread-safe libraries. It is also the best MPM for isolating each request, so that a problem with a single request will not affect any other.

The worker MPM implements a hybrid multi-process multi-threaded server and gives better performance, hence it should be preferred unless one is using other modules that contain non-thread-safe libraries (see also this discussion or this on Serverfault).

I think its also possible with adhoc queries you can export result to excel file and then import that file into your datatable object or use it as it is and then import the excel file into the second database have a look at this link this can help u alot.

http://vscontrols.blogspot.com/2010/09/import-and-export-excel-to-sql-server.html

There will be two Web.config files. I think you may have confused with those two files.

Check this image:

In this image you can see two Web.config files. You should add your constants to the one which is in the project folder not in the views folder

Hope this may help you

I adopted the answer from @Darkwaltz4 for its brevity and would like to share how I adapted the solution to situations where the array may contain different keys for each iteration like so:

Array[0] ...
['dob'] = '12/08/1986';
['some_key'] = 'some value';

Array[1] ...
['dob'] = '12/08/1986';

Array[2] ...
['dob'] = '12/08/1986';
['some_key'] = 'some other value';

and maintained a "master key" like so:

$master_key = array( 'dob' => ' ' ,  'some_key' => ' ' );

array_merge would have executed the merge in the Array[1] iteration based on $master_key and produced ['some_key'] = '', an empty value, for that iteration. Hence, array_intersect_key was used to modify $master_key in each iterations like so:

foreach ($customer as $customer) {
  $modified_key = array_intersect_key($master_key, $unordered_array);
  $properOrderedArray = array_merge($modified_key, $customer);
}

This is my answer,

<!DOCTYPE html>
<html>
<body>
<h2>Create Object from JSON String</h2>
<p>
First Name: <span id="fname"></span><br> 
Last Name: <span id="lname"></span><br>

<script>
var txt = '{"employees":[' +
'{"firstName":"John","lastName":"Doe" },' +
'{"firstName":"Anna","lastName":"Smith" },' +
'{"firstName":"Peter","lastName":"Jones" }]}';

//var jsonData = eval ("(" + txt + ")");
var jsonData = JSON.parse(txt);
for (var i = 0; i < jsonData.employees.length; i++) {
    var counter = jsonData.employees[i];
    //console.log(counter.counter_name);
    alert(counter.firstName);
}

</script>
</body>
</html>

If you are testing on localhost and you have no control of the response headers, you can disable it with a chrome flag.

Visit the url and disable it: chrome://flags/#same-site-by-default-cookies

I need to disable it because Chrome Canary just started enforcing this rule as of approximately V 82.0.4078.2 and now it's not setting these cookies.

Note: I only turn this flag on in Chrome Canary that I use for development. It's best not to turn the flag on for everyday Chrome browsing for the same reasons that google is introducing it.

$('#button').click(function(){
    $(this).addClass('active');
});

If you want to put the routes in a separate file, for example routes.js, you can create the routes.js file in this way:

module.exports = function(app){

    app.get('/login', function(req, res){
        res.render('login', {
            title: 'Express Login'
        });
    });

    //other routes..
}

And then you can require it from app.js passing the app object in this way:

require('./routes')(app);

Have also a look at these examples

https://github.com/visionmedia/express/tree/master/examples/route-separation

func( "1", "2", default, default, default, default, default, "eight" );

In my case (dynamically generating the sections): the issue was a missing "#" in href="#...".

There isn't a definite list, it's up to the browser. The only standard we have is DOM Level 2 HTML, according to which the only elements that have a focus() method are HTMLInputElement, HTMLSelectElement, HTMLTextAreaElement and HTMLAnchorElement. This notably omits HTMLButtonElement and HTMLAreaElement.

Today's browsers define focus() on HTMLElement, but an element won't actually take focus unless it's one of:

• HTMLAnchorElement/HTMLAreaElement with an href
• HTMLInputElement/HTMLSelectElement/HTMLTextAreaElement/HTMLButtonElement but not with disabled (IE actually gives you an error if you try), and file uploads have unusual behaviour for security reasons
• HTMLIFrameElement (though focusing it doesn't do anything useful). Other embedding elements also, maybe, I haven't tested them all.
• Any element with a tabindex

There are likely to be other subtle exceptions and additions to this behaviour depending on browser.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

Is not necessary to pass the data as JSON string, you can pass the object directly, without defining contentType or dataType, like this:

$.ajax({
    type: "POST",
    url: "TelephoneNumbers.aspx/DeleteNumber",
    data: data0,

    success: function(data)
    {
        alert('Done');
    }
});

Java 8 added a new way of making Comparators that reduces the amount of code you have to write, Comparator.comparing. Also check out Comparator.reversed

Here's a sample

import org.junit.Test;

import java.util.ArrayList;
import java.util.Comparator;
import java.util.List;

import static org.junit.Assert.assertTrue;

public class ComparatorTest {

    @Test
    public void test() {
        List<Person> peopleList = new ArrayList<>();
        peopleList.add(new Person("A", 1000));
        peopleList.add(new Person("B", 1));
        peopleList.add(new Person("C", 50));
        peopleList.add(new Person("Z", 500));
        //sort by name, ascending
        peopleList.sort(Comparator.comparing(Person::getName));
        assertTrue(peopleList.get(0).getName().equals("A"));
        assertTrue(peopleList.get(peopleList.size() - 1).getName().equals("Z"));
        //sort by name, descending
        peopleList.sort(Comparator.comparing(Person::getName).reversed());
        assertTrue(peopleList.get(0).getName().equals("Z"));
        assertTrue(peopleList.get(peopleList.size() - 1).getName().equals("A"));
        //sort by age, ascending
        peopleList.sort(Comparator.comparing(Person::getAge));
        assertTrue(peopleList.get(0).getAge() == 1);
        assertTrue(peopleList.get(peopleList.size() - 1).getAge() == 1000);
        //sort by age, descending
        peopleList.sort(Comparator.comparing(Person::getAge).reversed());
        assertTrue(peopleList.get(0).getAge() == 1000);
        assertTrue(peopleList.get(peopleList.size() - 1).getAge() == 1);
    }

    class Person {

        String name;
        int age;

        Person(String n, int a) {
            name = n;
            age = a;
        }

        public String getName() {
            return name;
        }

        public int getAge() {
            return age;
        }

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

        public void setAge(int age) {
            this.age = age;
        }
    }



}

If you are making your own module then add CommonModule in imports in your own module

Why not just wrap the "osopen" with a try/except and let the underlying OS sort out whether the file is valid?

This seems like much less work and is valid no matter which OS you use.

I think that MySql and MsSql won't allow this because they will try to find all columns in the CASE clause as columns of the tables in the WHERE clause.

I don't know what DBMS you are talking about, but I guess you could do something like this in any DBMS:

SELECT *, CASE WHEN a = 'test' THEN 'yes' END as value FROM (
   SELECT col1 as a FROM table
) q

tl;dr: Install 64-bit Git for Windows 2.

Technical details

      0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x68570000, RegionSize 0x2A0000, State 0x10000
PortableGit\bin\bash.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0

This symptom by itself has nothing to do with image bases of executables, corrupted Cygwin's shared memory sections, conflicting versions of DLLs etc.

It's Cygwin code failing to allocate a ~5 MB large chunk of memory for its heap at this fixed address 0x68570000, while only a hole ~2.5 MB large was apparently available there. The relevant code can be seen in msysgit source.

Why is that part of address space not free?

There can be many reasons. In my case it was some other modules loaded at a conflicting address:

The last address would be around 0x68570000 + 5 MB = 0x68C50000, but there are these WOW64-related DLLs loaded from 0x68810000 upwards, which block the allocation.

Whenever there is some shared DLL, Windows in general tries to load it at the same virtual address in all processes to save some relocation processing. It's just a matter of bad luck that these system components got somehow loaded at a conflicting address this time.

Why is there Cygwin in your Git?

Because Git is a rich suite consisting of some low level commands and a lot of helpful utilities, and mostly developed on Unix-like systems. In order to be able to build it and run it without massive rewriting, it need at least a partial Unix-like environment.

To accomplish that, people have invented MinGW and MSYS - a minimal set of build tools to develop programs on Windows in an Unix-like fashion. MSYS also contains a shared library, this msys-1.0.dll, which helps with some of the compatibility issues between the two platforms during runtime. And many parts of that have been taken from Cygwin, because someone already had to solve the same problems there.

So it's not Cygwin, it's MinGW's runtime DLL what's behaving weird here.

In Cygwin, this code has actually changed a lot since what's in MSYS 1.0 - the last commit message for that file says "Import Cygwin 1.3.4", which is from 2001!

Both current Cygwin and the new version of MSYS - MSYS2 - already have different logic in place, which is hopefully more robust. It's only old versions of Git for Windows which have been still built using the old broken MSYS system.

Clean solutions:

• Install Git for Windows 2 - it is built with the new, properly maintained MSYS2 and also has many new features, plenty of bug fixes, security improvements and so on. If at all possible, it is also recommended to use the 64-bit version. But the rebase workaround is performed automatically behind the scenes for 32-bit systems, so the chances of the problem happening there should be lower too.
• Simply restarting the computer to clean the address space (loading these modules at a different random address) might work, but really, just upgrade to Git for Windows 2 to get the security fixes if nothing else.

Hacky solutions:

• Changing PATH can sometimes work because there might be different versions of msys-1.0.dll in different versions of Git or other MSYS-based applications, which perhaps use different address, different size of this heap etc.
• Rebasing msys-1.0.dll might be a waste of time, because 1) being a DLL, it already has relocation information and 2) "in any version of Windows OS there is no guarantee that a (...) DLL will always load at same address space" anyway (source). The only way this can help is if the msys-1.0.dll itself loads at the conflicting address it's then trying to use. Apparently that's the case sometimes, as this is what the Git for Windows guys are doing automatically on 32-bit systems.
• Considering the findings above, I originally binary patched the msys-1.0.dll binary to use a different value for _cygheap_start and that resolved the problem immediately.

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

First, we're talking about packaging a Node.js app for workshops, demos, etc. where it can be handy to have an app "just running" without the need for the end user to care about installation and dependencies.

You can try the following setup:

1. Get your apps source code
2. npm install all dependencies (via package.json) to the local node_modules directory. It is important to perform this step on each platform you want to support separately, in case of binary dependencies.
3. Copy the Node.js binary – node.exe on Windows, (probably) /usr/local/bin/node on OS X/Linux to your project's root folder. On OS X/Linux you can find the location of the Node.js binary with which node.

For Windows:
Create a self extracting archive, 7zip_extra supports a way to execute a command right after extraction, see: http://www.msfn.org/board/topic/39048-how-to-make-a-7-zip-switchless-installer/.

For OS X/Linux:
You can use tools like makeself or unzipsfx (I don't know if this is compiled with CHEAP_SFX_AUTORUN defined by default).

These tools will extract the archive to a temporary directory, execute the given command (e.g. node app.js) and remove all files when finished.

you can use the library:OptionRoundCardview

I have the same problem, so I simply get JSON string and deserialize to my class:

HttpResponseMessage response = await client.GetAsync("Products");
//get data as Json string 
string data = await response.Content.ReadAsStringAsync();
//use JavaScriptSerializer from System.Web.Script.Serialization
JavaScriptSerializer JSserializer = new JavaScriptSerializer();
//deserialize to your class
products = JSserializer.Deserialize<List<Product>>(data);

\b matches a word-boundary. \B matches non-word-boundaries, and is equivalent to [^\b](?!\b) _{^{(thanks to @Alan Moore for the correction!)}}. Both are zero-width.

See http://www.regular-expressions.info/wordboundaries.html for details. The site is extremely useful for many basic regex questions.

Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!

The alignment-baseline property is what you're looking for it can take the following values

auto | baseline | before-edge | text-before-edge | 
middle | central | after-edge | text-after-edge | 
ideographic | alphabetic | hanging | mathematical | 
inherit

Description from w3c

This property specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes. It defaults to the baseline with the same name as the computed value of the alignment-baseline property. That is, the position of "ideographic" alignment-point in the block-progression-direction is the position of the "ideographic" baseline in the baseline-table of the object being aligned.

Unfortunately, although this is the "correct" way of achieving what you're after it would appear Firefox have not implemented a lot of the presentation attributes for the SVG Text Module ('SVG in Firefox' MDN Documentation)

You are getting an error because your getAll function in the Car class returns a single Car and you want to assign it into an array.

It's really not clear and you may want to post more code. why are you passing a single Car to the function? What is the meaning of calling getAll on a Car.

I think the only cookie you need is JSESSIONID=xxx..

Also NEVER share your cookies, becasuse someone may access your personal data that way. Specially when the cookies are session. These cookies will stop working once you logout the site.

If you want distinct values from only two fields, plus return other fields with them, then the other fields must have some kind of aggregation on them (sum, min, max, etc.), and the two columns you want distinct must appear in the group by clause. Otherwise, it's just as Decker says.

You Can simply Use One Jsp Page To accomplish the task.

std::string choppa(const std::string &t, const std::string &ws)
{
    std::string str = t;
    size_t found;
    found = str.find_last_not_of(ws);
    if (found != std::string::npos)
        str.erase(found+1);
    else
        str.clear();            // str is all whitespace

    return str;
}

This works for the null case as well. :-)

You can use Array.findIndex.

var data= [{
  "name": "placeHolder",
  "section": "right"
}, {
  "name": "Overview",
  "section": "left"
}, {
  "name": "ByFunction",
  "section": "left"
}, {
  "name": "Time",
  "section": "left"
}, {
  "name": "allFit",
  "section": "left"
}, {
  "name": "allbMatches",
  "section": "left"
}, {
  "name": "allOffers",
  "section": "left"
}, {
  "name": "allInterests",
  "section": "left"
}, {
  "name": "allResponses",
  "section": "left"
}, {
  "name": "divChanged",

}];
var index = data.findIndex(obj => obj.name=="allInterests");

console.log(index);

file Protocol
Opens a file on a local or network drive.

Syntax

Copy
 file:///sDrives[|sFile]
Tokens 

sDrives
Specifies the local or network drive.

sFile
Optional. Specifies the file to open. If sFile is omitted and the account accessing the drive has permission to browse the directory, a list of accessible files and directories is displayed.

Remarks

The file protocol and sDrives parameter can be omitted and substituted with just the command line representation of the drive letter and file location. For example, to browse the My Documents directory, the file protocol can be specified as file:///C|/My Documents/ or as C:\My Documents. In addition, a single '\' is equivalent to specifying the root directory on the primary local drive. On most computers, this is C:.

Available as of Microsoft Internet Explorer 3.0 or later.

Note Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Windows Internet Explorer followed the link to the local file.

Example

The following sample demonstrates four ways to use the File protocol.

Copy

//Specifying a drive and a file name. 

file:///C|/My Documents/ALetter.html

//Specifying only a drive and a path to browse the directory. 

file:///C|/My Documents/

//Specifying a drive and a directory using the command line representation of the directory location. 

C:\My Documents\

//Specifying only the directory on the local primary drive. 

\My Documents\

Jeffrey Hantin's answer is good but it has some constraints, if its this do this or else to that...

You can write your own extension method and it always works the way you want.

Lists.indexOf(array, x -> item == x); // compare in the way you want

And here is your extension

public final class Lists {
    private Lists() {
    }

    public static <T> int indexOf(T[] array, Predicate<T> predicate) {
        for (int i = 0; i < array.length; i++) {
            if (predicate.test(array[i])) return i;
        }
        return -1;
    }

    public static <T> int indexOf(List<T> list, Predicate<T> predicate) {
        for (int i = 0; i < list.size(); i++) {
            if (predicate.test(list.get(i))) return i;
        }
        return -1;
    }

    public interface Predicate<T> {
        boolean test(T t);
    }
}

To save others a few seconds, and to save them from having to read the manual, here's the short answer. Add this to the top of your make file:

.DEFAULT_GOAL := mytarget

mytarget will now be the target that is run if "make" is executed and no target is specified.

If you have an older version of make (<= 3.80), this won't work. If this is the case, then you can do what anon mentions, simply add this to the top of your make file:

.PHONY: default
default: mytarget ;

Rails >= 3.2 (including Rails 4+ and 5+):

class Countries < ActiveRecord::Base
  self.table_name = "cc"
end

Rails <= 3.1:

class Countries < ActiveRecord::Base
  self.set_table_name "cc"
  ...
end

A probably convenient way to enter multi-line strings is by using macro's. This only works if quotes and parentheses are balanced and it does not contain 'top level' comma's:

#define MULTI_LINE_STRING(a) #a
const char *text = MULTI_LINE_STRING(
  Using this trick(,) you don't need to use quotes.
  Though newlines and     multiple     white   spaces
  will be replaced by a single whitespace.
);
printf("[[%s]]\n",text);

Compiled with gcc 4.6 or g++ 4.6, this produces: [[Using this trick(,) you don't need to use quotes. Though newlines and multiple white spaces will be replaced by a single whitespace.]]

Note that the , cannot be in the string, unless it is contained within parenthesis or quotes. Single quotes is possible, but creates compiler warnings.

Edit: As mentioned in the comments, #define MULTI_LINE_STRING(...) #__VA_ARGS__ allows the use of ,.

It doesn't make a lot of sense, the original GAC was already quite capable of storing different versions of assemblies. And there's little reason to assume a program will ever accidentally reference the wrong assembly, all the .NET 4 assemblies got the [AssemblyVersion] bumped up to 4.0.0.0. The new in-process side-by-side feature should not change this.

My guess: there were already too many .NET projects out there that broke the "never reference anything in the GAC directly" rule. I've seen it done on this site several times.

Only one way to avoid breaking those projects: move the GAC. Back-compat is sacred at Microsoft.

According to this post, you should enable it in XCode.

1. Click on your project in the Project Navigator
2. Open the Info tab
3. Click on the down arrow left to the "App Transport Security Settings"
4. Right click on "App Transport Security Settings" and select Add Row
5. For created row set the key “Allow Arbitrary Loads“, type to boolean and value to YES.

This is phpMyAdmin method.

$query = "INSERT INTO myTable
         (mtb_i_idautoinc, mtb_s_string1, mtb_s_string2) 
         VALUES
         (NULL, 'Jagodina', '35000')";

Although similar in general cases ("run and get results for many tasks"), each function has some specific functionality for other cases:

asyncio.gather()

Returns a Future instance, allowing high level grouping of tasks:

import asyncio
from pprint import pprint

import random


async def coro(tag):
    print(">", tag)
    await asyncio.sleep(random.uniform(1, 3))
    print("<", tag)
    return tag


loop = asyncio.get_event_loop()

group1 = asyncio.gather(*[coro("group 1.{}".format(i)) for i in range(1, 6)])
group2 = asyncio.gather(*[coro("group 2.{}".format(i)) for i in range(1, 4)])
group3 = asyncio.gather(*[coro("group 3.{}".format(i)) for i in range(1, 10)])

all_groups = asyncio.gather(group1, group2, group3)

results = loop.run_until_complete(all_groups)

loop.close()

pprint(results)

All tasks in a group can be cancelled by calling group2.cancel() or even all_groups.cancel(). See also .gather(..., return_exceptions=True),

asyncio.wait()

Supports waiting to be stopped after the first task is done, or after a specified timeout, allowing lower level precision of operations:

import asyncio
import random


async def coro(tag):
    print(">", tag)
    await asyncio.sleep(random.uniform(0.5, 5))
    print("<", tag)
    return tag


loop = asyncio.get_event_loop()

tasks = [coro(i) for i in range(1, 11)]

print("Get first result:")
finished, unfinished = loop.run_until_complete(
    asyncio.wait(tasks, return_when=asyncio.FIRST_COMPLETED))

for task in finished:
    print(task.result())
print("unfinished:", len(unfinished))

print("Get more results in 2 seconds:")
finished2, unfinished2 = loop.run_until_complete(
    asyncio.wait(unfinished, timeout=2))

for task in finished2:
    print(task.result())
print("unfinished2:", len(unfinished2))

print("Get all other results:")
finished3, unfinished3 = loop.run_until_complete(asyncio.wait(unfinished2))

for task in finished3:
    print(task.result())

loop.close()

it work in my case, oldSensor and newSnsor - oldView and newView:

private void replaceSensors(View oldSensor, View newSensor) {
            ViewGroup parent = (ViewGroup) oldSensor.getParent();

            if (parent == null) {
                return;
            }

            int indexOldSensor = parent.indexOfChild(oldSensor);
            int indexNewSensor = parent.indexOfChild(newSensor);
            parent.removeView(oldSensor);
            parent.addView(oldSensor, indexNewSensor);
            parent.removeView(newSensor);
            parent.addView(newSensor, indexOldSensor);
        }

In Microsoft SQL Server Management Studio you can right-click on the database you wish to backup and click Tasks -> Generate Scripts.

This pops open a wizard where you can set the following in order to perform a decent backup of your database, even on a remote server:

• Select the database you wish to backup and hit next,
• In the options it presents to you:
  1. In 2010: under the Table/View Options, change 'Script Data' and 'Script Indexes' to True and hit next,
  2. In 2012: under 'General', change 'Types of data to script' from 'Schema only' to 'Schema and data'
  3. In 2014: the option to script the data is now "hidden" in step "Set Scripting Options", you have to click the "Advanced" and set "Types of data to script" to "Schema and data" value
• In the next four windows, hit 'select all' and then next,
• Choose to script to a new query window

Once it's done its thing, you'll have a backup script ready in front of you. Create a new local (or remote) database, and change the first 'USE' statement in the script to use your new database. Save the script in a safe place, and go ahead and run it against your new empty database. This should create you a (nearly) duplicate local database you can then backup as you like.

If you have full access to the remote database, you can choose to check 'script all objects' in the wizard's first window and then change the 'Script Database' option to True on the next window. Watch out though, you'll need to perform a full search & replace of the database name in the script to a new database which in this case you won't have to create before running the script. This should create a more accurate duplicate but is sometimes not available due to permissions restrictions.

You can access the id after calling the persist method of the entity manager.

$widgetEntity = new WidgetEntity();
$entityManager->persist($widgetEntity);
$entityManager->flush();
$widgetEntity->getId();

You do need to flush in order to get this id.

Syntax Error Fix: Added semi-colon after $entityManager->flush() is called.

In my opinion the sprintf-function deserves a place among these answers as well. You can use sprintf as follows:

do.call(sprintf, c(d[cols], '%s-%s-%s'))

which gives:

 [1] "a-d-g" "b-e-h" "c-f-i"

And to create the required dataframe:

data.frame(a = d$a, x = do.call(sprintf, c(d[cols], '%s-%s-%s')))

giving:

  a     x
1 1 a-d-g
2 2 b-e-h
3 3 c-f-i

Although sprintf doesn't have a clear advantage over the do.call/paste combination of @BrianDiggs, it is especially usefull when you also want to pad certain parts of desired string or when you want to specify the number of digit. See ?sprintf for the several options.

Another variant would be to use pmap from purrr:

pmap(d[2:4], paste, sep = '-')

Note: this pmap solution only works when the columns aren't factors.

A benchmark on a larger dataset:

# create a larger dataset
d2 <- d[sample(1:3,1e6,TRUE),]
# benchmark
library(microbenchmark)
microbenchmark(
  docp = do.call(paste, c(d2[cols], sep="-")),
  appl = apply( d2[, cols ] , 1 , paste , collapse = "-" ),
  tidr = tidyr::unite_(d2, "x", cols, sep="-")$x,
  docs = do.call(sprintf, c(d2[cols], '%s-%s-%s')),
  times=10)

results in:

Unit: milliseconds
 expr       min        lq      mean    median        uq       max neval cld
 docp  214.1786  226.2835  297.1487  241.6150  409.2495  493.5036    10 a  
 appl 3832.3252 4048.9320 4131.6906 4072.4235 4255.1347 4486.9787    10   c
 tidr  206.9326  216.8619  275.4556  252.1381  318.4249  407.9816    10 a  
 docs  413.9073  443.1550  490.6520  453.1635  530.1318  659.8400    10  b 

Used data:

d <- data.frame(a = 1:3, b = c('a','b','c'), c = c('d','e','f'), d = c('g','h','i')) 

you can try

"str".charCodeAt(0)

Tomasz Tybulewicz answer is good way to go.

SELECT * FROM pg_table_def WHERE tablename = 'YOUR_TABLE_NAME' AND schemaname = 'YOUR_SCHEMA_NAME';

If schema name is not defined in search path , that query will show empty result. Please first check search path by below code.

SHOW SEARCH_PATH

If schema name is not defined in search path , you can reset search path.

SET SEARCH_PATH to '$user', public, YOUR_SCEHMA_NAME

Path.GetDirectoryName(filename);

Replaced the reader declaration with this one and now it works!

Dim reader As New StreamReader(filetoimport.Text, Encoding.Default)

Encoding.Default represents the ANSI code page that is set under Windows Control Panel.

Just a tip.. Temporary tables in Oracle are different to SQL Server. You create it ONCE and only ONCE, not every session. The rows you insert into it are visible only to your session, and are automatically deleted (i.e., TRUNCATE, not DROP) when you end you session ( or end of the transaction, depending on which "ON COMMIT" clause you use).

Try this:

jQuery('#main').css('opacity', '0.6');

or

jQuery('#main').css({'filter':'alpha(opacity=60)', 'zoom':'1', 'opacity':'0.6'});

if you want to support IE7, IE8 and so on.

This page gives a decent breakdown of the different join types, as well as venn diagram visualizations to help... well... visualize the difference in the joins.

As the comments said this is a quite basic query from the sounds of it, so you should try to understand the differences between the joins and what they actually mean.

Check out http://blog.codinghorror.com/a-visual-explanation-of-sql-joins/

You're looking for a query such as:

DECLARE @table1 TABLE (test int)
DECLARE @table2 TABLE (test int)

INSERT INTO @table1
(
    test
)
SELECT 1
UNION ALL SELECT 2

INSERT INTO @table2
(
    test
)
SELECT 1
UNION ALL SELECT 3

-- Here's the important part
SELECT  a.*
FROM    @table1 a
LEFT    join @table2 b on a.test = b.test -- this will return all rows from a
WHERE   b.test IS null -- this then excludes that which exist in both a and b

-- Returned results:

• Create a 'popup' directive and apply it to the container of the popup content
• In the directive, wrap the content in a absolute position div along with the mask div below it.
• It is OK to move the 2 divs in the DOM tree as needed from within the directive. Any UI code is OK in the directives, including the code to position the popup in center of screen.
• Create and bind a boolean flag to controller. This flag will control visibility.
• Create scope variables that bond to OK / Cancel functions etc.

Editing to add a high level example (non functional)

<div id='popup1-content' popup='showPopup1'>
  ....
  ....
</div>


<div id='popup2-content' popup='showPopup2'>
  ....
  ....
</div>



.directive('popup', function() {
  var p = {
      link : function(scope, iElement, iAttrs){
           //code to wrap the div (iElement) with a abs pos div (parentDiv)
          // code to add a mask layer div behind 
          // if the parent is already there, then skip adding it again.
         //use jquery ui to make it dragable etc.
          scope.watch(showPopup, function(newVal, oldVal){
               if(newVal === true){
                   $(parentDiv).show();
                 } 
              else{
                 $(parentDiv).hide();
                }
          });
      }


   }
  return p;
});

I usually put these lines at the beginning of my stored procedure, and then at the end.

It is an "exists" check for #temp tables.

IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
begin
        drop table #MyCoolTempTable
end

Full Example:

CREATE PROCEDURE [dbo].[uspTempTableSuperSafeExample]
AS
BEGIN
    SET NOCOUNT ON;


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    CREATE TABLE #MyCoolTempTable (
        MyCoolTempTableKey INT IDENTITY(1,1),
        MyValue VARCHAR(128)
    )  

    INSERT INTO #MyCoolTempTable (MyValue)
        SELECT LEFT(@@VERSION, 128)
        UNION ALL SELECT TOP 10 LEFT(name, 128) from sysobjects

    SELECT MyCoolTempTableKey, MyValue FROM #MyCoolTempTable


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    SET NOCOUNT OFF;
END
GO

Yes, constructors are allowed to throw exceptions.

However, be very wise in choosing what exceptions they should be - checked exceptions or unchecked. Unchecked exceptions are basically subclasses of RuntimeException.

In almost all cases (I could not come up with an exception to this case), you'll need to throw a checked exception. The reason being that unchecked exceptions (like NullPointerException) are normally due to programming errors (like not validating inputs sufficiently).

The advantage that a checked exception offers is that the programmer is forced to catch the exception in his instantiation code, and thereby realizes that there can be a failure to create the object instance. Of course, only a code review will catch the poor programming practice of swallowing an exception.

In addition to making a symbolic link for apt_pkg.so, you may want to make apt_inst.so in the same manner of apt_pkg.so.

ln -s apt_inst.cpython-35m-x86_64-linux-gnu.so apt_inst.so 

This is old question but still my answer may help someone

For checking Java version in android studio version , simply open Terminal of Android Studio and type

java -version 

This will display java version installed in android studio

Use Rafael's solution: http://social.msdn.microsoft.com/Forums/en/sqlsetupandupgrade/thread/dddf0349-557b-48c7-bf82-6bd1adb5c694..

Added data from link to avoid link rot..

put this at any Console application:

string.Format("{0,3}", CultureInfo.InstalledUICulture.Parent.LCID.ToString("X")).Replace(" ", "0");

Watch the result. At mine it was "016".

Then you go to the registry at this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib

and create another one with the name you got from the string.Format result.

In my case:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\016"

and copy the info that is on any other key in this Perflib to this key you just created. Run the instalation again.

Just run the script and get your 3 digit code. Then follow his simple and quick steps, and you're ready to go!

Do you want to make the label (except for the text) transparent? Windows Forms (I assume WinForms - is this true) doesn't really support transparency. The easiest way, sometimes, is Label's Backcolor to Transparent.

label1.BackColor = System.Drawing.Color.Transparent;

You will run into problems though, as WinForms really doesn't properly support transparency. Otherwise, see here:

http://www.doogal.co.uk/transparent.php

http://www.codeproject.com/KB/dotnet/transparent_controls_net.aspx

http://www.daniweb.com/code/snippet216425.html

Setting the parent of a usercontrol prevents it from being transparent

Good luck!

Thanks all for your help but it is not complicated as it seems; almost everything is handled internally by SpringBoot.

In my case I want to use Mysql and Mongodb and the solution was to use EnableMongoRepositories and EnableJpaRepositories annotations on to my application class.

@SpringBootApplication
@EnableTransactionManagement
@EnableMongoRepositories(includeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
@EnableJpaRepositories(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
class TestApplication { ...

NB: All mysql entities have to extend JpaRepository and mongo enities have to extend MongoRepository.

The datasource configs are straight forward as presented by spring documentation:

//mysql db config
spring.datasource.url= jdbc:mysql://localhost:3306/tangio
spring.datasource.username=test
spring.datasource.password=test

#mongodb config
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=tangio
spring.data.mongodb.username=tangio
spring.data.mongodb.password=tangio
spring.data.mongodb.repositories.enabled=true

    }

    public Intent registerReceiver(BroadcastReceiver receiver, IntentFilter intentFilter) {
        receivers.add(receiver);
        Intent intent = cReference.get().registerReceiver(receiver, intentFilter);
        Log.i(getClass().getSimpleName(), "registered receiver: " + receiver + "  with filter: " + intentFilter);
        Log.i(getClass().getSimpleName(), "receiver Intent: " + intent);
        return intent;
    }

    public boolean isReceiverRegistered(BroadcastReceiver receiver) {
        boolean registered = receivers.contains(receiver);
        Log.i(getClass().getSimpleName(), "is receiver " + receiver + " registered? " + registered);
        return registered;
    }

    public void unregisterReceiver(BroadcastReceiver receiver) {
        if (isReceiverRegistered(receiver)) {
            receivers.remove(receiver);
            cReference.get().unregisterReceiver(receiver);
            Log.i(getClass().getSimpleName(), "unregistered receiver: " + receiver);
        }
    }
}

I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.

This answer is related to updating to MySQL 5.6 on machines with a small amount of RAM

I had the same problem when upgrading from MySQL 5.5 to 5.6 on my Debian 8 (Jessie). MySQL was not started (the status was showing active/exited) and simply making service mysql start did not work, because as I found from the /var/logs/mysql/error.log log file:

InnoDB: Initializing buffer pool, size = 128.0M
InnoDB: mmap(136019968 bytes) failed; errno 12
Cannot allocate memory for the buffer pool

The memory was not enough: I had only 256 MB of RAM.

In MySQL there is a setting, performance_schema. By default, it is turned off in MySQL 5.5.

https://dev.mysql.com/doc/refman/5.5/en/performance-schema-startup-configuration.html

But in MySQL 5.6 the default is on, and simply by adding the following line in /etc/mysql/my.cnf file and restarting, it worked.

performance_schema = off

Warning: Turning this setting off you might experience performance issues, but I guess in a development environment it won't be a problem.

Also, here is an article that might be helpful configuring MySQL to use minimal memory, Configuring MySQL to use minimal memory.

The currently accepted answer is incorrect. It is NOT required to set maxBufferSize and maxReceivedMessageSize on the client and the server binding. It depends!

If your request is too large (i.e., method parameters of the service operation are memory intensive) set the properties on the server-side, if the response is too large (i.e., the method return value of the service operation is memory intensive) set the values on the client-side.

For the difference between maxBufferSize and maxReceivedMessageSize see MaxBufferSize property?.

The equivalent JPA mapping for the DDL ON DELETE CASCADE is cascade=CascadeType.REMOVE. Orphan removal means that dependent entities are removed when the relationship to their "parent" entity is destroyed. For example if a child is removed from a @OneToMany relationship without explicitely removing it in the entity manager.

Monitor your Cached Files Size (you can use apc.php from apc pecl package) and increase apc.shm_size according to your needs.

This solves the problem.

I had this issue, I run 64 bit Windows and had downloaded the 64 bit TOAD package. I finally arrived at the conclusion that it was because I unzipped the package in a windows share using cygwin command line unzip. Turned out TOAD wasn't liking the permissions on some files. When I unzipped using windows File Explorer everything worked as expected.

In JavaScript, primitive types such as integers and strings are passed by value whereas objects are passed by reference. So in order to achieve this you need to use an object:

// declare an object with property x
var obj = { x: 1 };
var aliasToObj = obj;
aliasToObj.x ++;
alert( obj.x ); // displays 2

I know this is an old post, but I wanted to add something for posterity. The simple way of handling the issue that you have is to make another table, of value to key.

ie. you have 2 tables that have the same value, one pointing one direction, one pointing the other.

function addValue(key, value)
    if (value == nil) then
        removeKey(key)
        return
    end
    _primaryTable[key] = value
    _secodaryTable[value] = key
end

function removeKey(key)
    local value = _primaryTable[key]
    if (value == nil) then
        return
    end
    _primaryTable[key] = nil
    _secondaryTable[value] = nil
end

function getValue(key)
    return _primaryTable[key]
end

function containsValue(value)
    return _secondaryTable[value] ~= nil
end

You can then query the new table to see if it has the key 'element'. This prevents the need to iterate through every value of the other table.

If it turns out that you can't actually use the 'element' as a key, because it's not a string for example, then add a checksum or tostring on it for example, and then use that as the key.

Why do you want to do this? If your tables are very large, the amount of time to iterate through every element will be significant, preventing you from doing it very often. The additional memory overhead will be relatively small, as it will be storing 2 pointers to the same object, rather than 2 copies of the same object. If your tables are very small, then it will matter much less, infact it may even be faster to iterate than to have another map lookup.

The wording of the question however strongly suggests that you have a large number of items to deal with.

Make sure you have set database engine to InnoDB because in MyISAM foreign key and transaction are not supported

And about timing:

fn1 <- function (N) {
    for(i in as.numeric(1:N)) { y <- i*i }
}
fn2 <- function (N) {
    i=1
    while (i <= N) {
        y <- i*i
        i <- i + 1
    }
}

system.time(fn1(60000))
# user  system elapsed 
# 0.06    0.00    0.07 
system.time(fn2(60000))
# user  system elapsed 
# 0.12    0.00    0.13

And now we know that for-loop is faster than while-loop. You cannot ignore warnings during timing.

A lot of answer to this questions but a few were helping. I want to give accurate and updated answer.

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

This error happens when you bad internet connection or you put your computer to sleep while Android Studio is downloading the required dependencies.

How to resolve this issue.

1. Find out the project's Gradle version. You will find that in gradle-wrapper.properties in distributionUrl my gradle distribution was https\://services.gradle.org/distributions/gradle-6.5-all.zip that means gradle-6.5-all.zip is required to download and right now it is corrupted because of connection timeout. Lets find out this folder and delete this.
2. Go to .gradle folder then to wrapper then to dists then find a folder that matches the gradle version name that required to download. In my case it was gradle-6.5-all.zip select this folder and delete it.
3. Now sync the project and make sure you have good internet connection and setting that will prevent your system going to sleep while downloading something.

To add more information to the correct answer above, after reading an example from Android-er I found you can easily convert your preference activity into a preference fragment. If you have the following activity:

public class MyPreferenceActivity extends PreferenceActivity
{
    @Override
    protected void onCreate(final Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.my_preference_screen);
    }
}

The only changes you have to make is to create an internal fragment class, move the addPreferencesFromResources() into the fragment, and invoke the fragment from the activity, like this:

public class MyPreferenceActivity extends PreferenceActivity
{
    @Override
    protected void onCreate(final Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
    }

    public static class MyPreferenceFragment extends PreferenceFragment
    {
        @Override
        public void onCreate(final Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.my_preference_screen);
        }
    }
}

There may be other subtleties to making more complex preferences from fragments; if so, I hope someone notes them here.

In direct opposition to my other answer, this following function is probably safe, even with multi-byte characters.

// replace any non-ascii character with its hex code.
function escape($value) {
    $return = '';
    for($i = 0; $i < strlen($value); ++$i) {
        $char = $value[$i];
        $ord = ord($char);
        if($char !== "'" && $char !== "\"" && $char !== '\\' && $ord >= 32 && $ord <= 126)
            $return .= $char;
        else
            $return .= '\\x' . dechex($ord);
    }
    return $return;
}

I'm hoping someone more knowledgeable than myself can tell me why the code above won't work ...

If I find that the private method is huge or complex or important enough to require its own tests, I just put it in another class and make it public there (Method Object). Then I can easily test the previously private but now public method that now lives on its own class.

You should actually create a class:

class accum:
    def __init__(self):
        self.acc = 0
    def accumulator(self, var2add, end):
        if not end:
            self.acc+=var2add
    return self.acc

First, the code:

from random import choices

def random_name(length=6):
    return "".join(choices("abcdefghijklmnopqrstuvwxyz", k=length))
# ---

from IPython.display import IFrame, display, HTML
import tempfile
from os import unlink

def display_html_to_frame(html, width=600, height=600):
    name = f"temp_{random_name()}.html"
    with open(name, "w") as f:
        print(html, file=f)
    display(IFrame(name, width, height), metadata=dict(isolated=True))
    # unlink(name)
    
def display_html_inline(html):
    display(HTML(html, metadata=dict(isolated=True)))

h="<html><b>Hello</b></html>"    
display_html_to_iframe(h)
display_html_inline(h)

Some quick notes:

• You can generally just use inline HTML for simple items. If you are rendering a framework, like a large JavaScript visualization framework, you may need to use an IFrame. Its hard enough for Jupyter to run in a browser without random HTML embedded.
• The strange parameter, metadata=dict(isolated=True) does not isolate the result in an IFrame, as older documentation suggests. It appears to prevent clear-fix from resetting everything. The flag is no longer documented: I just found using it allowed certain display: grid styles to correctly render.
• This IFrame solution writes to a temporary file. You could use a data uri as described here but it makes debugging your output difficult. The Jupyter IFrame function does not take a data or srcdoc attribute.
• The tempfile module creations are not sharable to another process, hence the random_name().
• If you use the HTML class with an IFrame in it, you get a warning. This may be only once per session.
• You can use HTML('Hello, <b>world</b>') at top level of cell and its return value will render. Within a function, use display(HTML(...)) as is done above. This also allows you to mix display and print calls freely.
• Oddly, IFrames are indented slightly more than inline HTML.

A very basic approach is alert(arrayObj.join('\n')), which will display each array element in a row.

If you want many inserts

from rope.base.codeanalyze import ChangeCollector

c = ChangeCollector(code)
c.add_change(5, 5, '<span style="background-color:#339999;">')
c.add_change(10, 10, '</span>')
rend_code = c.get_changed()

Better solution, as str.split("\n") function creates new array of strings split by "\n" which is heavier than str.match(/\n\g). str.match(/\n\g) creates array of matching elements only. Which is "\n" in our case.

var totalLines = (str.match(/\n/g) || '').length + 1;

route -f causes damage. So we need to either disconnect the correct parts of the routing table or find out how to rebuild it.

On one project where we had 4 environments (development, test, staging and production) we developed a system where the application selected the appropriate configuration based on the machine name it was deployed to.

This worked for us because:

• administrators could deploy applications without involving developers (a requirement) and without having to fiddle with config files (which they hated);
• machine names adhered to a convention. We matched names using a regular expression and deployed to multiple machines in an environment; and
• we used integrated security for connection strings. This means we could keep account names in our config files at design time without revealing any passwords.

It worked well for us in this instance, but probably wouldn't work everywhere.

Try this:

setlocal EnableDelayedExpansion

...

for /F "tokens=*" %%a in ('type %FileName%') do (
    set z=%%a
    echo !z!
    echo %%a
)

Here's a quick and dirty way of inserting a column in a specific position on a data frame. In my case, I have 5 columns in the original data frame: c1, c2, c3, c4, c5 and I will insert a new column c2b between c2 and c3.

1) Let's first create the test data frame:

> dataset <- data.frame(c1 = 1:5, c2 = 2:6, c3=3:7, c4=4:8, c5=5:9)
> dataset
  c1 c2 c3 c4 c5
1  1  2  3  4  5
2  2  3  4  5  6
3  3  4  5  6  7
4  4  5  6  7  8
5  5  6  7  8  9

2) Add the new column c2b at the end of our data frame:

> dataset$c2b <- 10:14
> dataset
  c1 c2 c3 c4 c5 c2b
1  1  2  3  4  5  10
2  2  3  4  5  6  11
3  3  4  5  6  7  12
4  4  5  6  7  8  13
5  5  6  7  8  9  14

3) Reorder the data frame based on column indexes. In my case, I want to insert the new column (6) between existing columns 2 and 3. I do that by addressing the columns on my data frame using the vector c(1:2, 6, 3:5) which is equivalent to c(1, 2, 6, 3, 4, 5).

> dataset <- dataset[,c(1:2, 6, 3:5)]
> dataset
  c1 c2 c2b c3 c4 c5
1  1  2  10  3  4  5
2  2  3  11  4  5  6
3  3  4  12  5  6  7
4  4  5  13  6  7  8
5  5  6  14  7  8  9

There!

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

A load time dependency could not be resolved. The easiest way to debug this is to use Dependency Walker. Use the Profile option to get diagnostics output of the load process. This will identify the point of failure and should guide you to a solution.

The most common cause of this error is trying to load a 64 bit DLL into a 32 bit process, or vice versa.

If you need it to work on both Mac and Windows, you can use QueryTables:

With ActiveSheet.QueryTables.Add(Connection:="URL;http://carbon.brighterplanet.com/flights.txt", Destination:=Range("A2"))
    .PostText = "origin_airport=MSN&destination_airport=ORD"
    .RefreshStyle = xlOverwriteCells
    .SaveData = True
    .Refresh
End With

Notes:

• Regarding output... I don't know if it's possible to return the results to the same cell that called the VBA function. In the example above, the result is written into A2.
• Regarding input... If you want the results to refresh when you change certain cells, make sure those cells are the argument to your VBA function.
• This won't work on Excel for Mac 2008, which doesn't have VBA. Excel for Mac 2011 got VBA back.

For more details, you can see my full summary about "using web services from Excel."

And there is another possibility (not in this case) when working with ajax(XMLhttpRequest), while sending information back to the client end you should use res.send(responsetext) instead of res.end(responsetext)

Several options, by order of most appropriate way:

1. Return an int from the Program.Main method
2. Throw an exception and don't handle it anywhere (use for unexpected error situations)
3. To force termination elsewhere, System.Environment.Exit (not portable! see below)

Edited 9/2013 to improve readability

Returning with a specific exit code: As Servy points out in the comments, you can declare Main with an int return type and return an error code that way. So there really is no need to use Environment.Exit unless you need to terminate with an exit code and can't possibly do it in the Main method. Most probably you can avoid that by throwing an exception, and returning an error code in Main if any unhandled exception propagates there. If the application is multi-threaded you'll probably need even more boilerplate to properly terminate with an exit code so you may be better off just calling Environment.Exit.

Another point against using Evironment.Exit - even when writing multi-threaded applications - is reusability. If you ever want to reuse your code in an environment that makes Environment.Exit irrelevant (such as a library that may be used in a web server), the code will not be portable. The best solution still is, in my opinion, to always use exceptions and/or return values that represent that the method reached some error/finish state. That way, you can always use the same code in any .NET environment, and in any type of application. If you are writing specifically an app that needs to return an exit code or to terminate in a way similar to what Environment.Exit does, you can then go ahead and wrap the thread at the highest level and handle the errors/exceptions as needed.

Here you go with:

from b in _dbContext.Burden 
join bl in _dbContext.BurdenLookups on
new { Organization_Type = b.Organization_Type_ID, Cost_Type = b.Cost_Type_ID } equals
new { Organization_Type = bl.Organization_Type_ID, Cost_Type = bl.Cost_Type_ID }

SELECT * from SOME_TABLE where NAME like '%[^A-Z]%'

Or some other expression instead of A-Z

First, let me go over a few terms. If you just want your question answered, scroll down to "Answering your question".

Definitions

Object identity: When you create an object, you can assign it to a variable. You can then also assign it to another variable. And another.

>>> button = Button()
>>> cancel = button
>>> close = button
>>> dismiss = button
>>> print(cancel is close)
True

In this case, cancel, close, and dismiss all refer to the same object in memory. You only created one Button object, and all three variables refer to this one object. We say that cancel, close, and dismiss all refer to identical objects; that is, they refer to one single object.

Object equality: When you compare two objects, you usually don't care that it refers to the exact same object in memory. With object equality, you can define your own rules for how two objects compare. When you write if a == b:, you are essentially saying if a.__eq__(b):. This lets you define a __eq__ method on a so that you can use your own comparison logic.

Rationale for equality comparisons

Rationale: Two objects have the exact same data, but are not identical. (They are not the same object in memory.) Example: Strings

>>> greeting = "It's a beautiful day in the neighbourhood."
>>> a = unicode(greeting)
>>> b = unicode(greeting)
>>> a is b
False
>>> a == b
True

Note: I use unicode strings here because Python is smart enough to reuse regular strings without creating new ones in memory.

Here, I have two unicode strings, a and b. They have the exact same content, but they are not the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the unicode object has implemented the __eq__ method.

class unicode(object):
    # ...

    def __eq__(self, other):
        if len(self) != len(other):
            return False

        for i, j in zip(self, other):
            if i != j:
                return False

        return True

Note: __eq__ on unicode is definitely implemented more efficiently than this.

Rationale: Two objects have different data, but are considered the same object if some key data is the same. Example: Most types of model data

>>> import datetime
>>> a = Monitor()
>>> a.make = "Dell"
>>> a.model = "E770s"
>>> a.owner = "Bob Jones"
>>> a.warranty_expiration = datetime.date(2030, 12, 31)
>>> b = Monitor()
>>> b.make = "Dell"
>>> b.model = "E770s"
>>> b.owner = "Sam Johnson"
>>> b.warranty_expiration = datetime.date(2005, 8, 22)
>>> a is b
False
>>> a == b
True

Here, I have two Dell monitors, a and b. They have the same make and model. However, they neither have the same data nor are the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the Monitor object implemented the __eq__ method.

class Monitor(object):
    # ...

    def __eq__(self, other):
        return self.make == other.make and self.model == other.model

Answering your question

When comparing to None, always use is not. None is a singleton in Python - there is only ever one instance of it in memory.

By comparing identity, this can be performed very quickly. Python checks whether the object you're referring to has the same memory address as the global None object - a very, very fast comparison of two numbers.

By comparing equality, Python has to look up whether your object has an __eq__ method. If it does not, it examines each superclass looking for an __eq__ method. If it finds one, Python calls it. This is especially bad if the __eq__ method is slow and doesn't immediately return when it notices that the other object is None.

Did you not implement __eq__? Then Python will probably find the __eq__ method on object and use that instead - which just checks for object identity anyway.

When comparing most other things in Python, you will be using !=.

You can use "wildcards" with MATCH so assuming "ASDFGHJK" in H1 as per Peter's reply you can use this regular formula

=INDEX(G:G,MATCH("*"&H1&"*",G:G,0)+3)

MATCH can only reference a single column or row so if you want to search 6 columns you either have to set up a formula with 6 MATCH functions or change to another approach - try this "array formula", assuming search data in A2:G100

=INDIRECT("R"&REPLACE(TEXT(MIN(IF(ISNUMBER(SEARCH(H1,A2:G100)),(ROW(A2:G100)+3)*1000+COLUMN(A2:G100))),"000000"),4,0,"C"),FALSE)

• Parameter:
  • A value that is already "built in" to a function.
  • Parameters can be changed so that the function can be used for other things.
• Argument:
  • An input to a function
  • A variable that affects a functions result.

Source

I don't have a windows box handy to try this but I think you can use a DataView and do something like so:

DataView view = new DataView(ds.Tables["MyTable"]);
view.RowFilter = "MyValue = 42"; // MyValue here is a column name

// Delete these rows.
foreach (DataRowView row in view)
{
  row.Delete();
}

I haven't tested this, though. You might give it a try.

Another option is to create an additional "errata commit" (and push) which references the commit object that contains the error -- the new errata commit also provides the correction. An errata commit is a commit with no substantive code changes but an important commit message -- for example, add one space character to your readme file and commit that change with the important commit message, or use the git option --allow-empty. It's certainly easier and safer than rebasing, it doesn't modify true history, and it keeps the branch tree clean (using amend is also a good choice if you are correcting the most recent commit, but an errata commit may be a good choice for older commits). This type of thing so rarely happens that simply documenting the mistake is good enough. In the future, if you need to search through a git log for a feature keyword, the original (erroneous) commit may not appear because the wrong keyword was used in that original commit (the original typo) -- however, the keyword will appear in the errata commit which will then point you to the original commit that had the typo. Here's an example:

Here's my code, and it works:

function parseTableHtml(s) { // s is string
    var div = document.createElement('table');
    div.innerHTML = s;

    var tr = div.getElementsByTagName('tr');
    // ...
}

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:

1. Annotation settings are changed for the modules
2. Compiler output path is changed for the modules
3. Resources settings are ignored totally and only taken from pom.xml
4. Module dependencies are messed up and have to checked
5. Language/Encoding settings are changed for the modules

All these points need review and adjusting but after this it works like charm.

Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Edit 2019:

• Added recursive resource scan
• Added directory specification which might be important to avoid confusion of IDEA recarding the content root structure

I'm running into the same issue with one of my own apps. So far I've found the only non-deprecated way to access Google News data is through their RSS feeds. They have a feed for each section and also a useful search function. However, these are only for noncommercial use.

As for viable alternatives I'll be trying out these two services: Feedzilla, Daylife

cbindX from the package gdata combines multiple columns of differing column and row lengths. Check out the page here:

http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gdata/html/cbindX.html

It takes multiple comma separated matrices and data.frames as input :) You just need to

install.packages("gdata", dependencies=TRUE)

and then

library(gdata)
concat_data <- cbindX(df1, df2, df3) # or cbindX(matrix1, matrix2, matrix3, matrix4)

IEnumerable<string> e = (from char c in source
                        select new { Data = c.ToString() }).Select(t = > t.Data);
// or
IEnumerable<string> e = from char c in source
                        select c.ToString();
// or
IEnumerable<string> e = source.Select(c = > c.ToString());

Then you can call ToList():

List<string> l = (from char c in source
                  select new { Data = c.ToString() }).Select(t = > t.Data).ToList();
// or
List<string> l = (from char c in source
                  select c.ToString()).ToList();
// or
List<string> l = source.Select(c = > c.ToString()).ToList();

Use plain javascript methods

$x10Device = this.dataset("x10");

Use nm -a your.dylib

It will print all the symbols including globals

Had the same issue today. I added the user to:

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log on as a batch job

But was still getting the error. I found this post, and it turns out there's also this setting that I had to remove the user from (not sure how it got in there):

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Deny log on as a batch job

So just be aware that you may need to check both policies for the user.

Presuming every new branch in your tree is a div, I have implemented this solution with 2 functions:

function fillArray(vector1,vector2){
    for (var i = 0; i < vector1.length; i++){
        if (vector1[i].id.indexOf('q17_') == 0)
            vector2.push(vector1[i]);
        if(vector1[i].tagName == 'DIV')
            fillArray (document.getElementById(vector1[i].id).children,vector2);
    }
}

function selectAllElementsInsideDiv(divId){ 
    var matches = new Array();
    var searchEles = document.getElementById(divId).children;
    fillArray(searchEles,matches);
    return matches;
}

Now presuming your div's id is 'myDiv', all you have to do is create an array element and set its value to the function's return:

var ElementsInsideMyDiv = new Array();
ElementsInsideMyDiv =  selectAllElementsInsideDiv('myDiv')

I have tested it and it worked for me. I hope it helps you.

The var keyword in Javascript is there for a purpose.

If you declare a variable without the var keyword, like this:

myVar = 100;

It becomes a global variable that can be accessed from any part of your script. If you did not do it intentionally or are not aware of it, it can cause you pain if you re-use the variable name at another place in your javascript.

If you declare the variable with the var keyword, like this:

var myVar = 100;

It is local to the scope ({] - braces, function, file, depending on where you placed it).

This a safer way to treat variables. So unless you are doing it on purpose try to declare variable with the var keyword and not without.

If you don't want to change your database schema (and I would not for this simple query) you can just combine them in the filter like this: WHERE (Address1 + Address2) LIKE '%searchstring%'

I struggled to get this working. That's why I'll add a complete solution here:

My objective is to add this header to the SOAP envelope:

   <soapenv:Header>
      <urn:OTAuthentication>
         <urn:AuthenticationToken>TOKEN</urn:AuthenticationToken>
      </urn:OTAuthentication>
   </soapenv:Header>

1. First create a SOAPHeaderHandler class.

   import java.util.Set;
   import java.util.TreeSet;
   
   import javax.xml.namespace.QName;
   import javax.xml.soap.SOAPElement;
   import javax.xml.soap.SOAPEnvelope;
   import javax.xml.soap.SOAPFactory;
   import javax.xml.soap.SOAPHeader;
   import javax.xml.ws.handler.MessageContext;
   import javax.xml.ws.handler.soap.SOAPHandler;
   import javax.xml.ws.handler.soap.SOAPMessageContext;
   
   public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {
   
       private final String authenticatedToken;
   
       public SOAPHeaderHandler(String authenticatedToken) {
           this.authenticatedToken = authenticatedToken;
       }
   
       public boolean handleMessage(SOAPMessageContext context) {
           Boolean outboundProperty =
                   (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
           if (outboundProperty.booleanValue()) {
               try {
                   SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                   SOAPFactory factory = SOAPFactory.newInstance();
                   String prefix = "urn";
                   String uri = "urn:api.ecm.opentext.com";
                   SOAPElement securityElem =
                           factory.createElement("OTAuthentication", prefix, uri);
                   SOAPElement tokenElem =
                           factory.createElement("AuthenticationToken", prefix, uri);
                   tokenElem.addTextNode(authenticatedToken);
                   securityElem.addChildElement(tokenElem);
                   SOAPHeader header = envelope.addHeader();
                   header.addChildElement(securityElem);
               } catch (Exception e) {
                   e.printStackTrace();
               }
           } else {
               // inbound
           }
           return true;
       }
   
       public Set<QName> getHeaders() {
           return new TreeSet();
       }
   
       public boolean handleFault(SOAPMessageContext context) {
           return false;
       }
   
       public void close(MessageContext context) {
           //
       }
   }
   

   2. Add the handler to the proxy. Note that according javax.xml.ws.Binding's documentation: "If the returned chain is modified a call to setHandlerChain is required to configure the binding instance with the new chain."

   Authentication_Service authentication_Service = new Authentication_Service();
   
   Authentication basicHttpBindingAuthentication = authentication_Service.getBasicHttpBindingAuthentication();
   String authenticatedToken = "TOKEN";
   List<Handler> handlerChain = ((BindingProvider)basicHttpBindingAuthentication).getBinding().getHandlerChain();
   handlerChain.add(new SOAPHeaderHandler(authenticatedToken));
   ((BindingProvider)basicHttpBindingAuthentication).getBinding().setHandlerChain(handlerChain);
   

For .js files that expose more than one variable (unlike drawGauge), a better solution would be to set the Typescript compiler to process .js files.

In your tsconfig.json, set allowJs option to true:

"compilerOptions": {
     ...
    "allowJs": true,
     ...
}

Otherwise, you'll have to declare each and every variable in either your component.ts or d.ts.

Take out the MONTHS from your case, and remove the brackets... like this:

CASE 
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

You can think of this as being equivalent to:

CASE TRUE
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

try this:

SELECT * FROM TableA
JOIN TableB ON TableA.primary_key = TableB.foreign_key 
JOIN TableB ON TableB.foreign_key = TableC.foreign_key

Flex-boxes are the solution - and they're fantastic. I've been wanting something like this out of css for a decade. All you need is to add display: flex to your style for "Main" and flex-grow: 100 (where 100 is arbitrary - its not important that it be exactly 100). Try adding this style (colors added to make the effect visible):

<style>
    #Main {
        background-color: lightgray;
        display: flex;
    }

    #div1 {
        border: 1px solid green;   
        height: 50px; 
        display: inline-flex; 
    }
    #div2 {
        border: 1px solid blue;    
        height: 50px;
        display: inline-flex;
        flex-grow: 100;
    }
    #div3 {
        border: 1px solid orange;        
        height: 50px;
        display: inline-flex;
    }
</style>

More info about flex boxes here: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

First you should create a form with or without Border (border-less is preferred for these things)

public class SplashForm : Form
{
    Form _Parent;
    BackgroundWorker worker;
    public SplashForm(Form parent)
    {
         InitializeComponent();
         BackgroundWorker worker = new BackgroundWorker();
         this.worker.DoWork += new System.ComponentModel.DoWorkEventHandler(this.worker _DoWork);
         backgroundWorker1.RunWorkerAsync();
         _Parent = parent;
    }
    private void worker _DoWork(object sender, DoWorkEventArgs e)
    {
         Thread.sleep(500);
         this.hide();
         _Parent.show();
    }     
}

At Main you should use that

   static class Program
        {
            [STAThread]
            static void Main()
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new SplashForm());
            }
        }

Constraint layout aims at reducing layout hierarchies and improves performance of layouts(technically, you don't have to make changes for different screen sizes,No overlapping, works like charm on a mobile as well as a tab with the same constraints).Here's how you get rid of the above error when you're using the new layout editor.

Click on the small circle and drag it to the left until the circle turns green,to add a left constraint(give a number, say x dp. Repeat it with the other sides and leave the bottom constraint blank if you have another view below it.

Edit: According to the developers site, Instead of adding constraints to every view as you place them in the layout, you can move each view into the positions you desire, and then click Infer Constraints to automatically create constraints. more here

Though it is too late, I have found a better solution (that works for me) that will replace all consecutive same type white spaces with one white space of its type. That is:

   Hello!\n\n\nMy    World  

will be

 Hello!\nMy World 

Notice there are still leading and trailing white spaces. So my complete solution is:

str = str.trim().replaceAll("(\\s)+", "$1"));

Here, trim() replaces all leading and trailing white space strings with "". (\\s) is for capturing \\s (that is white spaces such as ' ', '\n', '\t') in group #1. + sign is for matching 1 or more preceding token. So (\\s)+ can be consecutive characters (1 or more) among any single white space characters (' ', '\n' or '\t'). $1 is for replacing the matching strings with the group #1 string (which only contains 1 white space character) of the matching type (that is the single white space character which has matched). The above solution will change like this:

   Hello!\n\n\nMy    World  

will be

Hello!\nMy World

I have not found my above solution here so I have posted it.

This will work.

    USE INFORMATION_SCHEMA;
    SELECT TABLE_SCHEMA, TABLE_NAME
    FROM information_schema.tables
    WHERE TABLE_TYPE LIKE 'VIEW';

Use the CSS function from jQuery to set styles to your items :

$('#buttonId').css({ "background-color": 'brown'});

Try using combination of map and lambda functions:

aList = map( lambda x: x, set ([1, 2, 6, 9, 0]) )

It is very convenient approach if you have a set of numbers in string and you want to convert it to list of integers:

aList = map( lambda x: int(x), set (['1', '2', '3', '7', '12']) )

Non of these solutions worked for my case:

• missing objects can exist in either array
• runtime complexity of O(n)

notes:

• I used lodash but it's easy to replace with something else
• Also used Typescript (just remove/ignore the types)

import { keyBy, values } from 'lodash';

interface IStringTMap<T> {
  [key: string]: T;
}

type IIdentified = {
  id?: string | number;
};

export function mergeArrayById<T extends IIdentified>(
  array1: T[],
  array2: T[]
): T[] {
  const mergedObjectMap: IStringTMap<T> = keyBy(array1, 'id');

  const finalArray: T[] = [];

  for (const object of array2) {
    if (object.id && mergedObjectMap[object.id]) {
      mergedObjectMap[object.id] = {
        ...mergedObjectMap[object.id],
        ...object,
      };
    } else {
      finalArray.push(object);
    }
  }

  values(mergedObjectMap).forEach(object => {
    finalArray.push(object);
  });

  return finalArray;
}

If you're just starting out learning javascript & don't want to spend time creating an entire webpage just for embedding test scripts, just open Dev Tools in a new tab in Chrome Browser, and click on Console.

Then type out some test scripts: eg.

console.log('Aha!') 

Then press Enter after every line (to submit for execution by Chrome)

or load your own "external script file":

document.createElement('script').src = 'http://example.com/file.js';

Then call your functions:

console.log(file.function('?????'))

Tested in Google Chrome 85.0.4183.121

When I needed to do this, I followed Microsoft's example using Binding.ValidationRules and it worked first time.

See their article, How to: Implement Binding Validation: https://docs.microsoft.com/en-us/dotnet/desktop/wpf/data/how-to-implement-binding-validation?view=netframeworkdesktop-4.8

Error shows that script does not exists

The file does not exists. check your full path

C:\Windows\TEMP\hudson6299483223982766034.sh
The system cannot find the file specified

Moreover, to launch .sh scripts into windows, you need to have CYGWIN installed and well configured into your path

Confirm that script exists.

Into jenkins script, do the following to confirm that you do have the file

cd C:\Windows\TEMP\
ls -rtl
sh -xe hudson6299483223982766034.sh

As pointed out by Thomas Stjernegaard Jeppesen, you could use History.js to modify URL parameters whilst the user navigates through your Ajax links and apps.

Almost an year has passed since that answer, and History.js grew and became more stable and cross-browser. Now it can be used to manage history states in HTML5-compliant as well as in many HTML4-only browsers. In this demo You can see an example of how it works (as well as being able to try its functionalities and limits.

Should you need any help in how to use and implement this library, i suggest you to take a look at the source code of the demo page: you will see it's very easy to do.

Finally, for a comprehensive explanation of what can be the issues about using hashes (and hashbangs), check out this link by Benjamin Lupton.

Check your monitor scaling.

My problem turned out to be this:

It turned out to be different DPI-scaling on the primary and secondary monitor. When the secondary monitor was set to 125% (same as the primary monitor) the icons appeared again.

I ran into the same issue, for whatever reason Visual Studio did not update the web config when I first added the service. I found that updating the Service Reference also fixed this issue.

Steps:

1. Navigate to the Service Reference Folder
2. Expand it
3. Right Click and Select update Service Reference
4. Observe web Config be updated

I had this issue on Arch Linux too... it costs me some time but I'm happy now that I found my mistake:

My directory with the .html files where in my account.
I set everything on r+x but I still got the 403 error.
Than I went completely back and tried to set my home-directory to execute which solved my problem.

This has resolved my issue, just added data-orderable="false" in <th></th> like this <th data-orderable="false">Salary</th>

They're generally stored on the server. Where they're stored is up to you as the developer. You can use the session.save_handler configuration variable and the session_set_save_handler to control how sessions get saved on the server. The default save method is to save sessions to files. Where they get saved is controlled by the session.save_path variable.

500 Internal Server Error is shown if your php code has fatal errors but error displaying is switched off. You may try this to see the error itself instead of 500 error page:

In your php file:

ini_set('display_errors', 1);

In .htaccess file:

php_flag display_errors 1

While Alsk has already given a pretty detailed answer, I'd like to add an alternative, since I think his enhanced implementation is overcomplicated.

We start with an abstract base class, that provides the interface for all the object types:

class Object
{
public:
    virtual char* GetClassName() = 0;
};

Now we need an actual implementation. But to avoid having to write both the static and the virtual methods, we will have our actual object classes inherit the virtual methods. This does obviously only work, if the base class knows how to access the static member function. So we need to use a template and pass the actual objects class name to it:

template<class ObjectType>
class ObjectImpl : public Object
{
public:
    virtual char* GetClassName()
    {
        return ObjectType::GetClassNameStatic();
    }
};

Finally we need to implement our real object(s). Here we only need to implement the static member function, the virtual member functions will be inherited from the ObjectImpl template class, instantiated with the name of the derived class, so it will access it's static members.

class MyObject : public ObjectImpl<MyObject>
{
public:
    static char* GetClassNameStatic()
    {
        return "MyObject";
    }
};

class YourObject : public ObjectImpl<YourObject>
{
public:
    static char* GetClassNameStatic()
    {
        return "YourObject";
    }
};

Let's add some code to test:

char* GetObjectClassName(Object* object)
{
    return object->GetClassName();
}

int main()
{
    MyObject myObject;
    YourObject yourObject;

    printf("%s\n", MyObject::GetClassNameStatic());
    printf("%s\n", myObject.GetClassName());
    printf("%s\n", GetObjectClassName(&myObject));
    printf("%s\n", YourObject::GetClassNameStatic());
    printf("%s\n", yourObject.GetClassName());
    printf("%s\n", GetObjectClassName(&yourObject));

    return 0;
}

Addendum (Jan 12th 2019):

Instead of using the GetClassNameStatic() function, you can also define the the class name as a static member, even "inline", which IIRC works since C++11 (don't get scared by all the modifiers :)):

class MyObject : public ObjectImpl<MyObject>
{
public:
    // Access this from the template class as `ObjectType::s_ClassName` 
    static inline const char* const s_ClassName = "MyObject";

    // ...
};

Use an interval:

select some_date_column + interval '1' hour 
from your_table;

Edit the following entry in the run.conf file. But if you have multiple JVMs running on the same JBoss, you might want to run it via command line argument of -Xms2g -Xmx4g (or whatever your preferred start/max memory settings are.

if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2g -Xmx4g -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true

You're correct, in that example the throws is superfluous. It's possible that it was left there from some previous implementation - perhaps the exception was originally thrown instead of caught in the catch block.

For my case, the problem was due to losing of the internet connection in my WiFi.

I received this error code 0x800A03EC when trying to save an Excel file created within my .Net application in VS 2017. I changed the Excel.Application object property Visible=True and let it run until the point of failure. Tried to finish the steps manually in Excel and then discovered I could not save the file because of missing folder permissions. I added the Write permission to the folder, and the error went away.

def quit(self):
    self.root.destroy()

Add parentheses after destroy to call the method.

When you use command=self.root.destroy you pass the method to Tkinter.Button without the parentheses because you want Tkinter.Button to store the method for future calling, not to call it immediately when the button is created.

But when you define the quit method, you need to call self.root.destroy() in the body of the method because by then the method has been called.

Try this. Your markup:

<div id="MyId" runat="server">some content</div>

.. and in aspx.cs file:

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["someSessionVal"].ToString() == "some value")
    {
        MyId.Visible = true;
    }
    else
    {
        MyId.Visible = false;
    }
}

In my case the issue was not resolved because i did not restart my system. Please make sure you do restart your system.

No need for extra software. Use the task scheduler -> create task -> hidden. The checkbox for hidden is in the bottom left corner. Set the task to trigger on login (or whatever condition you like) and choose the task in the actions tab. Running it hidden ensures that the task runs silently in the background like a service.

Note that you must also set the program to run "whether the user is logged in or not" or the program will still run in the foreground.

This code below works for me. I always use only single quotes, and it works fine. I suggest you should use only single quotes or only double quotes, but not mixed up.

$.ajax({
    url: 'YourRestEndPoint',
    headers: {
        'Authorization':'Basic xxxxxxxxxxxxx',
        'X-CSRF-TOKEN':'xxxxxxxxxxxxxxxxxxxx',
        'Content-Type':'application/json'
    },
    method: 'POST',
    dataType: 'json',
    data: YourData,
    success: function(data){
      console.log('succes: '+data);
    }
  });

My problem (and so solution) was yet different from those described above.

I wasn't using models.py file, but created a models directory and created the my_model.py file there, where I put my model. Django couldn't find my model so it wrote that there are no migrations to apply.

My solution was: in the my_app/models/__init__.py file I added this line: from .my_model import MyModel

According to AWS documentation [https://aws.amazon.com/premiumsupport/knowledge-center/instance-store-vs-ebs/] instance store volumes is not persistent through instance stops, terminations, or hardware failures. Any AMI created from instance stored disk doesn't contain data present in instance store so all instances launched by this AMI will not have data stored in instance store. Instance store can be used as cache for applications running on instance, for all persistent data you should use EBS.

Simply use datetime.datetime.strptime:

import datetime
stime = "01/12/2011"
print(datetime.datetime.strptime(stime, "%d/%m/%Y").timestamp())

Result:

1322697600

To use UTC instead of the local timezone use .replace:

datetime.datetime.strptime(stime, "%d/%m/%Y").replace(tzinfo=datetime.timezone.utc).timestamp()

Using String#gsub with regular expression:

"((String1))".gsub(/^\(+|\)+$/, '')
# => "String1"
"(((((( parentheses )))".gsub(/^\(+|\)+$/, '')
# => " parentheses "

This will remove surrounding parentheses only.

"(((((( This (is) string )))".gsub(/^\(+|\)+$/, '')
# => " This (is) string "

You can also provide a negative number as an argument to the round method to round to the nearest multiple of 10, 100 and so on.

# Round to the nearest multiple of 10. 
12.3453.round(-1)       # Output: 10

# Round to the nearest multiple of 100. 
124.3453.round(-2)      # Output: 100

The KILL SESSION command doesn't actually kill the session. It merely asks the session to kill itself. In some situations, like waiting for a reply from a remote database or rolling back transactions, the session will not kill itself immediately and will wait for the current operation to complete. In these cases the session will have a status of "marked for kill". It will then be killed as soon as possible.

Check the status to confirm:

SELECT sid, serial#, status, username FROM v$session;

You could also use IMMEDIATE clause:

ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

The IMMEDIATE clause does not affect the work performed by the command, but it returns control back to the current session immediately, rather than waiting for confirmation of the kill. Have a look at Killing Oracle Sessions.

Update If you want to kill all the sessions, you could just prepare a small script.

SELECT 'ALTER SYSTEM KILL SESSION '''||sid||','||serial#||''' IMMEDIATE;' FROM v$session;

Spool the above to a .sql file and execute it, or, copy paste the output and run it.

To resolve this problem in Visual Studio 2012, I right click the project, properties -> "signing", and then uncheck the "Sign the ClickOnce manifests".

In C#, I had problem with checking RadioButton, and this worked for me:

driver.ExecuteJavaScript("arguments[0].checked=true", radio);

For those looking to use axios-mock-adapter in place of the mockfetch example in the Redux documentation for async testing, I successfully used the following:

File actions.test.js:

describe('SignInUser', () => {
  var history = {
    push: function(str) {
        expect(str).toEqual('/feed');
    }
  }

  it('Dispatches authorization', () => {
    let mock = new MockAdapter(axios);
    mock.onPost(`${ROOT_URL}/auth/signin`, {
        email: '[email protected]',
        password: 'test'
    }).reply(200, {token: 'testToken' });

    const expectedActions = [ { type: types.AUTH_USER } ];
    const store = mockStore({ auth: [] });

    return store.dispatch(actions.signInUser({
        email: '[email protected]',
        password: 'test',
      }, history)).then(() => {
        expect(store.getActions()).toEqual(expectedActions);
  });

});

In order to test a successful case for signInUser in file actions/index.js:

export const signInUser = ({ email, password }, history) => async dispatch => {
  const res = await axios.post(`${ROOT_URL}/auth/signin`, { email, password })
    .catch(({ response: { data } }) => {
        ...
  });

  if (res) {
    dispatch({ type: AUTH_USER });                 // Test verified this
    localStorage.setItem('token', res.data.token); // Test mocked this
    history.push('/feed');                         // Test mocked this
  }
}

Given that this is being done with jest, the localstorage call had to be mocked. This was in file src/setupTests.js:

const localStorageMock = {
  removeItem: jest.fn(),
  getItem: jest.fn(),
  setItem: jest.fn(),
  clear: jest.fn()
};
global.localStorage = localStorageMock;

Based on the answer by Korakot Chaovavanich, I created the function below to download all files needed within a Colab instance.

from google.colab import files
def getLocalFiles():
    _files = files.upload()
    if len(_files) >0:
       for k,v in _files.items():
         open(k,'wb').write(v)
getLocalFiles()

You can then use the usual 'import' statement to import your local files in Colab. I hope this helps

If you are trying to debug your virtual host configuration, you may find the Apache -S command line switch useful. That is, type the following command:

httpd -S

This command will dump out a description of how Apache parsed the configuration file. Careful examination of the IP addresses and server names may help uncover configuration mistakes. (See the docs for the httpd program for other command line options).

Press Shift-zz. Saves changes and Quits. Escape didn't work for me.

I am using Git Bash in windows. And couldn't get past this either. My commit messages are simple so I dont want to add another editor atm.

The modern approach is to move away from VBA for important code, and write a .NET managed Add-In using c# or vb.net, there are a lot of resources for this on the www, and you could use the Express version of MS Visual Studio

You're adding the event handler to the <select> element.
Therefore, $(this) will be the dropdown itself, not the selected <option>.

You need to find the selected <option>, like this:

var option = $('option:selected', this).attr('mytag');

foreach (int x in chklstTerms.CheckedIndices)
{
    chklstTerms.SelectedIndex=x;
    termids.Add(chklstTerms.SelectedValue.ToString());
}

Do

npm install

to install Grunt locally in ./node_modules (and everything else specified in the package.json file)

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

Thanks for this thread -- it helped me a lot too.

I learned something about .join() today.

These threads run in parallel:

d.start()
t.start()
d.join()
t.join()

and these run sequentially (not what I wanted):

d.start()
d.join()
t.start()
t.join()

In particular, I was trying to clever and tidy:

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()
        self.join()

This works! But it runs sequentially. I can put the self.start() in __ init __, but not the self.join(). That has to be done after every thread has been started.

join() is what causes the main thread to wait for your thread to finish. Otherwise, your thread runs all by itself.

So one way to think of join() as a "hold" on the main thread -- it sort of de-threads your thread and executes sequentially in the main thread, before the main thread can continue. It assures that your thread is complete before the main thread moves forward. Note that this means it's ok if your thread is already finished before you call the join() -- the main thread is simply released immediately when join() is called.

In fact, it just now occurs to me that the main thread waits at d.join() until thread d finishes before it moves on to t.join().

In fact, to be very clear, consider this code:

import threading
import time

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()

    def run(self):
        print self.time, " seconds start!"
        for i in range(0,self.time):
            time.sleep(1)
            print "1 sec of ", self.time
        print self.time, " seconds finished!"


t1 = Kiki(3)
t2 = Kiki(2)
t3 = Kiki(1)
t1.join()
print "t1.join() finished"
t2.join()
print "t2.join() finished"
t3.join()
print "t3.join() finished"

It produces this output (note how the print statements are threaded into each other.)

$ python test_thread.py
32   seconds start! seconds start!1

 seconds start!
1 sec of  1
 1 sec of 1  seconds finished!
 21 sec of
3
1 sec of  3
1 sec of  2
2  seconds finished!
1 sec of  3
3  seconds finished!
t1.join() finished
t2.join() finished
t3.join() finished
$ 

The t1.join() is holding up the main thread. All three threads complete before the t1.join() finishes and the main thread moves on to execute the print then t2.join() then print then t3.join() then print.

Corrections welcome. I'm also new to threading.

(Note: in case you're interested, I'm writing code for a DrinkBot, and I need threading to run the ingredient pumps concurrently rather than sequentially -- less time to wait for each drink.)

If you are on a PC then you can run My Phone Explorer on the PC, the MyPhoneExplorer Client on the phone, set the screen capture to refresh continuously, and use Wink to capture a custom rectangular area of your screen over the My Phone Explorer window with your own capture rate. Then convert to a FLV in Wink, then convert from Flash video to MPG with WinFF.

If you are using Java 1.4 or newer, you can use the simple method setLocationRelativeTo(null) on the dialog box, frame, or window to center it.

private static byte[] charArrayToByteArray(char[] c_array) {
        byte[] b_array = new byte[c_array.length];
        for(int i= 0; i < c_array.length; i++) {
            b_array[i] = (byte)(0xFF & (int)c_array[i]);
        }
        return b_array;
}

Because '' is not a valid Javascript/JSON object. An empty object would be '{}'

For reference: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

I was having the same problem with the fetch command. A quick look at the docs from here tells us this:

If the server you are requesting from doesn't support CORS, you should get an error in the console indicating that the cross-origin request is blocked due to the CORS Access-Control-Allow-Origin header being missing.

You can use no-cors mode to request opaque resources.

fetch('https://bar.com/data.json', {
  mode: 'no-cors' // 'cors' by default
})
.then(function(response) {
  // Do something with response
});

In this case, the selecteditem bind doesn't work, because the hash id of the objects are different.

One possible solution is:

Based on the selected item id, recover the object on the itemsource collection and set the selected item property to with it.

Example:

<ctrls:ComboBoxControlBase SelectedItem="{Binding Path=SelectedProfile, Mode=TwoWay}" ItemsSource="{Binding Path=Profiles, Mode=OneWay}" IsEditable="False" DisplayMemberPath="Name" />

The Property binded to ItemSource is:

public ObservableCollection<Profile> Profiles
{
   get { return this.profiles; }
   private set { profiles = value; RaisePropertyChanged("Profiles"); }
}

The property binded to SelectedItem is:

public Profile SelectedProfile 
{
    get { return selectedProfile; }
    set
    {
        if (this.SelectedUser != null)
        {
            this.SelectedUser.Profile = value; 
            RaisePropertyChanged("SelectedProfile");  
        } 
    } 
}

The recovery code is:

    [Command("SelectionChanged")]
    public void SelectionChanged(User selectedUser)
    {
        if (selectedUser != null)
        {
            if (selectedUser is User)
            {
                if (selectedUser.Profile != null)
                {
                    this.SelectedUser = selectedUser;
                    this.selectedProfile = this.Profiles.Where(p => p.Id == this.SelectedUser.Profile.Id).FirstOrDefault();
                    MessageBroker.Instance.NotifyColleagues("ShowItemDetails"); 
                }
            }
        }            
    }

I hope it helps you. I spent a lot of my time searching for answers, but I couldn´t find.

'T' represents a generic type. It means it can accept any type of class. The following article might help:

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

If you're doing this in the context of a search engine or frontend against a database, you might consider using a tool like Apache Solr, with the ComplexPhraseQueryParser plugin. This combination allows you to search against an index of strings with the results sorted by relevance, as determined by Levenshtein distance.

We've been using it against a large collection of artists and song titles when the incoming query may have one or more typos, and it's worked pretty well (and remarkably fast considering the collections are in the millions of strings).

Additionally, with Solr, you can search against the index on demand via JSON, so you won't have to reinvent the solution between the different languages you're looking at.

those are miliseconds, just divide them by 1000, since gmtime expects seconds ...

time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(1236472051807/1000.0))

If you're testing for all zeros to avoid a warning on another numpy function then wrapping the line in a try, except block will save having to do the test for zeros before the operation you're interested in i.e.

try: # removes output noise for empty slice 
    mean = np.mean(array)
except:
    mean = 0

You can do it in a simpler way , like the below:

boolean IsEqualStringandEnum (String str,Enum enum)
{
  if (str.equals(enum.toString()))
     return true;
  else
     return false;
}

For example, my vector<int> foo contains (5,2,6,87,251). A function takes vector<int>* and I want to pass it a pointer to (2,6,87,251).

A pointer to a vector<int> is not at all the same thing as a pointer to the elements of the vector.

In order to do this you will need to create a new vector<int> with just the elements you want in it to pass a pointer to. Something like:

 vector<int> tempVector( foo.begin()+1, foo.end());

 // now you can pass &tempVector to your function

However, if your function takes a pointer to an array of int, then you can pass &foo[1].

Yes, nowadays you can develop apps for iOS in Python.

There are two frameworks that you may want to checkout: Kivy and PyMob.

Please consider the answers to this question too, as they are more up-to-date than this one.

Less text is required with this approach:

ls -r | ? {$_.mode -match "d"}

To add a file/folder to the project, a good way is:

First of all add your files to /path/to/your/project/my/added/files, and then run following commands:

svn cleanup  /path/to/your/project

svn add --force /path/to/your/project/*

svn cleanup  /path/to/your/project

svn commit /path/to/your/project  -m 'Adding a file'

I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.

I had the same problem and fixed it by going to File->Project Structure->Project and changing the Android Plugin Version to 1.3.0-beta1

My Answer is specifically for Redmi/Mi Phone users. I faced this issue multiple times.

Sometimes we uninstall the app but it is not completely uninstalled but app will not display on screen and also it will not be listed in Settings -> Apps.

After checking multiple answers, What worked for me is below command

Go to Android Studio and click on Terminal tab in bottom of Android Studio. Connect your device, once adb detects your device, Run this command and try again to Run your application. Hope it will help.

adb uninstall com.shyam.smsapp

com.shyam.smsapp replace with your application package name

An inner class is associated with an instance of the outer class and there are two special kinds: Local class and Anonymous class. An anonymous class enables us to declare and instantiate a class at same time, hence makes the code concise. We use them when we need a local class only once as they don't have a name.

Consider the example from doc where we have a Person class:

public class Person {

    public enum Sex {
        MALE, FEMALE
    }

    String name;
    LocalDate birthday;
    Sex gender;
    String emailAddress;

    public int getAge() {
        // ...
    }

    public void printPerson() {
        // ...
    }
}

and we have a method to print members that match search criteria as:

public static void printPersons(
    List<Person> roster, CheckPerson tester) {
    for (Person p : roster) {
        if (tester.test(p)) {
            p.printPerson();
        }
    }
}

where CheckPerson is an interface like:

interface CheckPerson {
    boolean test(Person p);
}

Now we can make use of anonymous class which implements this interface to specify search criteria as:

printPersons(
    roster,
    new CheckPerson() {
        public boolean test(Person p) {
            return p.getGender() == Person.Sex.MALE
                && p.getAge() >= 18
                && p.getAge() <= 25;
        }
    }
);

Here the interface is very simple and the syntax of anonymous class seems unwieldy and unclear.

Java 8 has introduced a term Functional Interface which is an interface with only one abstract method, hence we can say CheckPerson is a functional interface. We can make use of Lambda Expression which allows us to pass the function as method argument as:

printPersons(
                roster,
                (Person p) -> p.getGender() == Person.Sex.MALE
                        && p.getAge() >= 18
                        && p.getAge() <= 25
        );

We can use a standard functional interface Predicate in place of the interface CheckPerson, which will further reduce the amount of code required.

You will need to use reflection to get the type "TestRunner". Use the Assembly.GetType method.

class Program
{
    static void Main(string[] args)
    {
        Assembly assembly = Assembly.LoadFile(@"C:\dyn.dll");
        Type type = assembly.GetType("TestRunner");
        var obj = (TestRunner)Activator.CreateInstance(type);
        obj.Run();
    }
}
