If someone says you can't because only Windows can control the non-client area, they're wrong!

That's just a half-truth because Windows lets you specify the dimensions of the non-client area. The fact is, this is possible only throughout the Windows' kernel methods, and you're in .NET, not C/C++. Anyway, don't worry! P/Invoke was meant just for such things! Indeed, the whole of the Windows Form UI and Console application Std-I/O methods are offered using system calls. Hence, you'd have only to perform the right system calls to set the non-client area up, as documented in MSDN.

However, this is a really hard solution I came up with a lot of time ago. Luckily, as of .NET 4.5, you can use the WindowChrome class to adjust the non-client area like you want. Here you can get to start with.

In order to make things simpler and cleaner, I'll redirect you here, a guide to change the window border dimensions to whatever you want. By setting it to 0, you'll be able to implement your custom window border in place of the system's one.

I'm sorry for not posting a clear example, but later I will for sure.

MySQL support is simple to add. In your DATABASES dictionary, you will have an entry like this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'DB_NAME',
        'USER': 'DB_USER',
        'PASSWORD': 'DB_PASSWORD',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    }
}

You also have the option of utilizing MySQL option files, as of Django 1.7. You can accomplish this by setting your DATABASES array like so:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'OPTIONS': {
            'read_default_file': '/path/to/my.cnf',
        },
    }
}

You also need to create the /path/to/my.cnf file with similar settings from above

[client]
database = DB_NAME
host = localhost
user = DB_USER
password = DB_PASSWORD
default-character-set = utf8

With this new method of connecting in Django 1.7, it is important to know the order connections are established:

1. OPTIONS.
2. NAME, USER, PASSWORD, HOST, PORT
3. MySQL option files.

In other words, if you set the name of the database in OPTIONS, this will take precedence over NAME, which would override anything in a MySQL option file.

If you are just testing your application on your local machine, you can use

python manage.py runserver

Adding the ip:port argument allows machines other than your own to access your development application. Once you are ready to deploy your application, I recommend taking a look at the chapter on Deploying Django on the djangobook

Mysql default character set is often not utf-8, therefore make sure to create your database using this sql:

CREATE DATABASE mydatabase CHARACTER SET utf8 COLLATE utf8_bin

If you are using Oracle's MySQL connector your ENGINE line should look like this:

'ENGINE': 'mysql.connector.django',

Note that you will first need to install mysql on your OS.

brew install mysql (MacOS)

Also, the mysql client package has changed for python 3 (MySQL-Client works only for python 2)

pip3 install mysqlclient

I will first say that having a favicon in a Web page is a good thing (normally).

However it is not always desired and sometime developers need a way to avoid the extra payload. For example an IFRAME would request a favicon without showing it. Worst yet, in Chrome and Android an IFRAME will generate 3 requests for favicons:

"GET /favicon.ico HTTP/1.1" 404 183
"GET /apple-touch-icon-precomposed.png HTTP/1.1" 404 197
"GET /apple-touch-icon.png HTTP/1.1" 404 189

The following uses data URI and can be used to avoid fake favicon requests:

<link rel="shortcut icon" href="data:image/x-icon;," type="image/x-icon"> 

For references see here:

UPDATE 1:

From the comments (jpic) it looks like Firefox >= 25 doesn't like the above syntax anymore. I tested on Firefox 27 and it doesn't work while it still work on Webkit/Chrome.

So here is the new one that should cover all recent browsers. I tested Safari, Chrome and Firefox:

<link rel="icon" href="data:;base64,=">

I left out the "shortcut" name from the "rel" attribute value since that's only for older IE and versions of IE < 8 doesn't like dataURIs either. Not tested on IE8.

UPDATE 2:

If you need your document to validate against HTML5 use this instead:

<link rel="icon" href="data:;base64,iVBORw0KGgo=">

One way is to use re.sub, that's my preferred way.

import re
my_str = "hey th~!ere"
my_new_string = re.sub('[^a-zA-Z0-9 \n\.]', '', my_str)
print my_new_string

Output:

hey there

Another way is to use re.escape:

import string
import re

my_str = "hey th~!ere"

chars = re.escape(string.punctuation)
print re.sub(r'['+chars+']', '',my_str)

Output:

hey there

Just a small tip about parameters style in python by PEP-8 parameters should be remove_special_chars and not removeSpecialChars

Also if you want to keep the spaces just change [^a-zA-Z0-9 \n\.] to [^a-zA-Z0-9\n\.]

When I found that there was no process using port 80 by using commands

netstat -abno | find ":80"

there was not a problem of any process using port 80.

Then I ran command (in cmd)

C:\xampp\apache\bin\httpd.exe

it showed some error in the virtual hosts configuration in httpd-vhosts.conf file which was recently edited by me for installation in a WordPress PHP environment in the Eclipse IDE. So I deleted those lines and Apache started perfectly.

Use this manual http://blog.antoine.li/2010/10/22/android-trusting-ssl-certificates/ This guide really helped me. It is important to observe a sequence of certificates in the store. For example: import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.

There is many way; but if you don't want to create a new Object or structure or something like this you can do like below after C# 7.0 :

 (string firstName, string lastName) GetName(string myParameter)
    {
        var firstName = myParameter;
        var lastName = myParameter + " something";
        return (firstName, lastName);
    }

    void DoSomethingWithNames()
    {
        var (firstName, lastName) = GetName("myname");

    }

For everybody who uses Rider you have to select your project>Right Click>Properties>Configurations Then select Debug and Release and check "Allow unsafe code" for both.

There's more to it than this, but you're probably looking for this list:

C   custom business day frequency (experimental)
D   calendar day frequency
W   weekly frequency
M   month end frequency
BM  business month end frequency
MS  month start frequency
BMS business month start frequency

Dates are stored in their timestamp format. If you want everything that belongs to a specific month, query for the start and the end of the month.

var start = new Date(2010, 11, 1);
var end = new Date(2010, 11, 30);

db.posts.find({created_on: {$gte: start, $lt: end}});
//taken from http://cookbook.mongodb.org/patterns/date_range/

I encountered a rare edge case in cygwin, where I would get this error when doing exec('rsync'); somewhere before the query. Might be a general PHP problem, but I could only reproduce this in cygwin with rsync.

$pdo = new PDO('mysql:host=127.0.0.1;dbname=mysql', 'root');
var_dump($pdo->query('SELECT * FROM db'));
exec('rsync');
var_dump($pdo->query('SELECT * FROM db'));

produces

object(PDOStatement)#2 (1) {
   ["queryString"]=>
   string(16) "SELECT * FROM db"
}

I use Use Prettier Formatter and ESLint VS Code extension together for code linting and formating.

now install some packages using given command, if more packages required they will show with installation command as an error in the terminal for you, please install them also.

npm i eslint prettier eslint@^5.16.0 eslint-config-prettier eslint-plugin-prettier eslint-config-airbnb eslint-plugin-node eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks@^2.5.0 --save-dev

now create a new file name .prettierrc in your project home directory, using this file you can configure settings of the prettier extension, my settings are below:

{
  "singleQuote": true
}

now as for the ESlint you can configure it according to your requirement, I am advising you to go Eslint website see the rules (https://eslint.org/docs/rules/)

Now create a file name .eslintrc.json in your project home directory, using that file you can configure eslint, my configurations are below:

{
  "extends": ["airbnb", "prettier", "plugin:node/recommended"],
  "plugins": ["prettier"],
  "rules": {
    "prettier/prettier": "error",
    "spaced-comment": "off",
    "no-console": "warn",
    "consistent-return": "off",
    "func-names": "off",
    "object-shorthand": "off",
    "no-process-exit": "off",
    "no-param-reassign": "off",
    "no-return-await": "off",
    "no-underscore-dangle": "off",
    "class-methods-use-this": "off",
    "prefer-destructuring": ["error", { "object": true, "array": false }],
    "no-unused-vars": ["error", { "argsIgnorePattern": "req|res|next|val" }]
  }
}

This doesn't work and it shouldn't because it would be a giant security hole.

Have a look at the new File System API. It allows you to request access to a virtual, sandboxed filesystem governed by the browser. You will have to request your user to "upload" their file into the sandboxed filesystem once, but afterwards you can work with it very elegantly.

While this definitely is the future, it is still highly experimental and only works in Google Chrome as far as CanIUse knows.

For a bit of facts here is the relevant text from the specifications

Equality operator (==,!=)

Pointers to objects of the same type can be compared for equality with the 'intuitive' expected results:

From § 5.10 of the C++11 standard:

Pointers of the same type (after pointer conversions) can be compared for equality. Two pointers of the same type compare equal if and only if they are both null, both point to the same function, or both represent the same address (3.9.2).

(leaving out details on comparison of pointers to member and or the null pointer constants - they continue down the same line of 'Do What I Mean':)

• [...] If both operands are null, they compare equal. Otherwise if only one is null, they compare unequal.[...]

The most 'conspicuous' caveat has to do with virtuals, and it does seem to be the logical thing to expect too:

• [...] if either is a pointer to a virtual member function, the result is unspecified. Otherwise they compare equal if and only if they would refer to the same member of the same most derived object (1.8) or the same subobject if they were dereferenced with a hypothetical object of the associated class type. [...]

Relational operators (<,>,<=,>=)

From § 5.9 of the C++11 standard:

Pointers to objects or functions of the same type (after pointer conversions) can be compared, with a result defined as follows:

1. If two pointers p and q of the same type point to the same object or function, or both point one past the end of the same array, or are both null, then p<=q and p>=q both yield true and p<q and p>q both yield false.
2. If two pointers p and q of the same type point to different objects that are not members of the same object or elements of the same array or to different functions, or if only one of them is null, the results of p<q, p>q, p<=q, and p>=q are unspecified.
3. If two pointers point to non-static data members of the same object, or to subobjects or array elements of such members, recursively, the pointer to the later declared member compares greater provided the two members have the same access control (Clause 11) and provided their class is not a union.
4. If two pointers point to non-static data members of the same object with different access control (Clause 11) the result is unspecified.
5. If two pointers point to non-static data members of the same union object, they compare equal (after conversion to void*, if necessary). If two pointers point to elements of the same array or one beyond the end of the array, the pointer to the object with the higher subscript compares higher.
6. Other pointer comparisons are unspecified.

So, if you had:

int arr[3];
int *a = arr;
int *b = a + 1;
assert(a != b); // OK! well defined

Also OK:

struct X { int x,y; } s;
int *a = &s.x;
int *b = &s.y;
assert(b > a); // OK! well defined

But it depends on the something in your question:

int g; 
int main()
{
     int h;
     int i;

     int *a = &g;
     int *b = &h; // can't compare a <=> b
     int *c = &i; // can't compare b <=> c, or a <=> c etc.
     // but a==b, b!=c, a!=c etc. are supported just fine
}

Bonus: what else is there in the standard library?

§ 20.8.5/8: "For templates greater, less, greater_equal, and less_equal, the specializations for any pointer type yield a total order, even if the built-in operators <, >, <=, >= do not."

So, you can globally order any odd void* as long as you use std::less<> and friends, not bare operator<.

You can use the below code to print all column names; You can also modify the code to print other details in whichever format u like

    declare @Result varchar(max)='
            '
            select @Result=@Result+''+ColumnName+'
            '
            from
            (
                select
                    replace(col.name, ' ', '_') ColumnName,
                    column_id ColumnId
                from sys.columns col
                    join sys.types typ on
                        col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
                where object_id = object_id('tblPracticeTestSections')
            ) t
            order by ColumnId
            print @Result

Output

column1
column2
column3
column4

To use the same code to print the table and its column name as C# class use the below code:

    declare @TableName sysname = '<EnterTableName>'
    declare @Result varchar(max) = 'public class ' + @TableName + '
    {'

    select @Result = @Result + '
        public static string ' + ColumnName + ' { get { return "'+ColumnName+'"; } }
    '
    from
    (
        select
            replace(col.name, ' ', '_') ColumnName,
            column_id ColumnId
        from sys.columns col
            join sys.types typ on
                col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
        where object_id = object_id(@TableName)
    ) t
    order by ColumnId

    set @Result = @Result  + '
    }'

    print @Result

Output:

 public class tblPracticeTestSections
 {
   public static string column1 { get { return "column1"; } }

   public static string column2{ get { return "column2"; } }

   public static string column3{ get { return "column3"; } }

   public static string column4{ get { return "column4"; } }

 } 

public class StringsCount{

    public static void main(String args[]) {

        String value = "This is testing Program testing Program";

        String item[] = value.split(" ");

        HashMap<String, Integer> map = new HashMap<>();

        for (String t : item) {
            if (map.containsKey(t)) {
                map.put(t, map.get(t) + 1);

            } else {
                map.put(t, 1);
            }
        }
        Set<String> keys = map.keySet();
        for (String key : keys) {
            System.out.println(key);
            System.out.println(map.get(key));
        }

    }
}

try it out with the following code

function fun1()  
{  
   $this->db->select('count(DISTINCT(accessid))');  
   $this->db->from('accesslog');  
   $this->db->where('record =','123');  
   $query=$this->db->get();  
   return $query->num_rows();  
}

SELECT COALESCE(
    (SELECT SUM(Price) AS TotalPrice 
    FROM Inventory
    WHERE (DateAdded BETWEEN @StartDate AND @EndDate))
    , 0)

If the table has rows in the response it returns the SUM(Price). If the SUM is NULL or there are no rows it will return 0.

Putting COALESCE(SUM(Price), 0) does NOT work in MSSQL if no rows are found.

When you use a blade echo {{ $data }} it will automatically escape the output. It can only escape strings. In your data $data->ac is an array and $data is an object, neither of which can be echoed as is. You need to be more specific of how the data should be outputted. What exactly that looks like entirely depends on what you're trying to accomplish. For example to display the link you would need to do {{ $data->ac[0][0]['url'] }} (not sure why you have two nested arrays but I'm just following your data structure).

@foreach($data->ac['0'] as $link)
    <a href="{{ $link['url'] }}">This is a link</a>
@endforeach

If you're converting anything other than simple types like integers or booleans, you'd need to write your own function/method for the type that you're trying to convert, otherwise PHP will just print the type (such as array, GoogleSniffer, or Bidet).

That is an very old post but I faced to a similar problem and I would like to share my experience with you guys.

I am building microservice architecture with rest APIs. I have some rest GET services, they collect data from back-end system based on the request parameters.

I followed the rest API design documents and I sent back HTTP 404 with a perfect JSON error message to client when there was no data which align to the query conditions (for example zero record was selected).

When there was no data to sent back to the client I prepared an perfect JSON message with internal error code, etc. to inform the client about the reason of the "Not Found" and it was sent back to the client with HTTP 404. That works fine.

Later I have created a rest API client class which is an easy helper to hide the HTTP communication related code and I used this helper all the time when I called my rest APIs from my code.

BUT I needed to write confusing extra code just because HTTP 404 had two different functions:

• the real HTTP 404 when the rest API is not available in the given url, it is thrown by the application server or web-server where the rest API application runs
• client get back HTTP 404 as well when there is no data in database based on the where condition of the query.

Important: My rest API error handler catches all the exceptions appears in the back-end service which means in case of any error my rest API always returns with a perfect JSON message with the message details.

This is the 1st version of my client helper method which handles the two different HTTP 404 response:

public static String getSomething(final String uuid) {
    String serviceUrl = getServiceUrl();
    String path = "user/" + , uuid);
    String requestUrl = serviceUrl + path;
    String httpMethod = "GET";

    Response response = client
            .target(serviceUrl)
            .path(path)
            .request(ExtendedMediaType.APPLICATION_UTF8)
            .get();

    if (response.getStatus() == Response.Status.OK.getStatusCode()) {
        // HTTP 200
        return response.readEntity(String.class);
    } else {
        // confusing code comes here just because
        // I need to decide the type of HTTP 404...

        // trying to parse response body
        try {
            String responseBody = response.readEntity(String.class);
            ObjectMapper mapper = new ObjectMapper();
            ErrorInfo errorInfo = mapper.readValue(responseBody, ErrorInfo.class);

            // re-throw the original exception
            throw new MyException(errorInfo);

        } catch (IOException e) {
            // this is a real HTTP 404
            throw new ServiceUnavailableError(response, requestUrl, httpMethod);
        }

    // this exception will never be thrown
    throw new Exception("UNEXPECTED ERRORS, BETTER IF YOU DO NOT SEE IT IN THE LOG");
}

BUT, because my Java or JavaScript client can receive two kind of HTTP 404 somehow I need to check the body of the response in case of HTTP 404. If I can parse the response body then I am sure I got back a response where there was no data to send back to the client.

If I am not able to parse the response that means I got back a real HTTP 404 from the web server (not from the rest API application).

It is so confusing and the client application always needs to do extra parsing to check the real reason of HTTP 404.

Honestly I do not like this solution. It is confusing, needs to add extra bullshit code to clients all the time.

So instead of using HTTP 404 in this two different scenarios I decided that I will do the following:

• I am not using HTTP 404 as a response HTTP code in my rest application anymore.
• I am going to use HTTP 204 (No Content) instead of HTTP 404.

In that case client code can be more elegant:

public static String getString(final String processId, final String key) {
    String serviceUrl = getServiceUrl();
    String path = String.format("key/%s", key);
    String requestUrl = serviceUrl + path;
    String httpMethod = "GET";

    log(requestUrl);

    Response response = client
            .target(serviceUrl)
            .path(path)
            .request(ExtendedMediaType.APPLICATION_JSON_UTF8)
            .header(CustomHttpHeader.PROCESS_ID, processId)
            .get();

    if (response.getStatus() == Response.Status.OK.getStatusCode()) {
        return response.readEntity(String.class);
    } else {
        String body = response.readEntity(String.class);
        ObjectMapper mapper = new ObjectMapper();
        ErrorInfo errorInfo = mapper.readValue(body, ErrorInfo.class);
        throw new MyException(errorInfo);
    }

    throw new AnyServerError(response, requestUrl, httpMethod);
}

I think this handles that issue better.

If you have any better solution please share it with us.

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

this is baked into python per PEP -> https://www.python.org/dev/peps/pep-0378/

just use format(1000, ',d') to show an integer with thousands separator

there are more formats described in the PEP, have at it

I had to extract numbers first from a list of float strings:

   df4['sscore'] = df4['simscore'].str.findall('\d+\.\d+')

then each convert to a float:

   ad=[]
   for z in range(len(df4)):
      ad.append([float(i) for i in df4['sscore'][z]])

in the end assign all floats to a dataframe as float64:

   df4['fscore'] = np.array(ad,dtype=float)

Revised Answer

If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:

var myname varchar2(20);

exec :myname := 'Tom';

SELECT *
FROM   Customers
WHERE  Name = :myname;

In many tools (such as Toad and SQL Developer), omitting the var and exec statements will cause the program to prompt you for the value.

Original Answer

A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT (roughly equivalent to print) to output the variable:

DECLARE
   myname varchar2(20);
BEGIN
     myname := 'Tom';

     dbms_output.print_line(myname);
END;

This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:

CREATE FUNCTION my_function (myname in varchar2)
     my_refcursor out sys_refcursor
BEGIN
     open my_refcursor for
     SELECT *
     FROM   Customers
     WHERE  Name = myname;

     return my_refcursor;
END my_function;

Sorry to necro, but this is the first google search result. This is the solution that worked for me:

1. Download numpy+mkl wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy. Use the version that is the same as your python version (check using python -V). Eg. if your python is 3.5.2, download the wheel which shows cp35

2. Open command prompt and navigate to the folder where you downloaded the wheel. Run the command: pip install [file name of wheel]

3. Download the SciPy wheel from: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy (similar to the step above).

4. As above, pip install [file name of wheel]

It looks like a common gaps-and-islands problem. The difference between two sequences of row numbers rn1 and rn2 give the "group" number.

Run this query CTE-by-CTE and examine intermediate results to see how it works.

Sample data

I expanded sample data from the question a little.

DECLARE @Source TABLE
(
    EmployeeID int,
    DateStarted date,
    DepartmentID int
)

INSERT INTO @Source

There is no LEAD function in SQL Server 2008, so I had to use self-join via OUTER APPLY to get the value of the "next" row for the DateEnd.

The two common to print a blank line in Python-

1. The old school way:

2. Writing the word print alone would do that:

For those who are finding for a thread safe solution, take a look here.

Code:

UPDATE Account 
SET    sg_status = 'A'
OUTPUT INSERTED.AccountId --You only need this if you want to return some column of the updated item
WHERE  AccountId = 
(
    SELECT TOP 1 AccountId 
    FROM Account WITH (UPDLOCK) --this is what makes the query thread safe!
    ORDER  BY CreationDate 
)

To drop all columns with values 0 in any row:

new_df = df[df.loc[:]!=0].dropna()

Get fields where a timestamp is greater than date in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > to_date('05 Dec 2000', 'DD Mon YYYY');

Subtract minutes from timestamp in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > current_timestamp - interval '5 minutes'

Subtract hours from timestamp in postgresql:

SELECT * from yourtable 
WHERE your_timestamp_field > current_timestamp - interval '5 hours'

If you are using MinGW, the problem is that by default, MinGW uses the I/O resp. formatting functions from the Microsoft C runtime, which doesn't support 80 bit floating point numbers (long double == double in Microsoft land).

However, MinGW also comes with a set of alternative implementations that do properly support long doubles. To use them, prefix the function names with __mingw_ (e.g. __mingw_printf). Depending on the nature of your project, you might also want to globally #define printf __mingw_printf or use -D__USE_MINGW_ANSI_STDIO (which enables the MinGW versions of all the printf-family functions).

Try @Cacheable from jcabi-aspects. With a single annotation you make the entire method result cacheable in memory:

public class Resource {
  @Cacheable(lifetime = 5, unit = TimeUnit.SECONDS)
  public String load(URL url) {
    return url.openConnection().getContent();
  }
}

Also, read this article: http://www.yegor256.com/2014/08/03/cacheable-java-annotation.html

This was just happening to me, but none of the suggestions above worked. I changed directories ("cd ~/tmp") and suddenly the command

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

worked for me. Prior to changing directories I had been in a directory that is a Git repository. Perhaps that was interfering with the ruby and Git commands in the Brew install script.

Still using indirect. Say your A1 cell is your variable that will contain the name of the referenced sheet (Jan). If you go by:

=INDIRECT(CONCATENATE("'",A1," Item'", "!J3"))

Then you will have the 'Jan Item'!J3 value.

Embedded C is generally an extension of the C language, they are more or less similar. However, some differences do exist, such as:

• C is generally used for desktop computers, while embedded C is for microcontroller based applications.

• C can use the resources of a desktop PC like memory, OS, etc. While, embedded C has to use with the limited resources, such as RAM, ROM, I/Os on an embedded processor.

• Embedded C includes extra features over C, such as fixed point types, multiple memory areas, and I/O register mapping.

• Compilers for C (ANSI C) typically generate OS dependant executables. Embedded C requires compilers to create files to be downloaded to the microcontrollers/microprocessors where it needs to run.

     String s1 = "HelloSuresh";
     String m = s1.replace("Hello","");
     System.out.println(m);

How about something like this :

string url = "http://www.example.com/aaa/bbb.jpg";
Uri uri = new Uri(url);
string path_Query = uri.PathAndQuery;
string extension =  Path.GetExtension(path_Query);

path_Query = path_Query.Replace(extension, string.Empty);// This will remove extension

to validate the email string you will need to write a regular expression to check it is in the correct form. there are plenty out on the web but be carefull as some can exclude what are actually legal addresses.

essentially it will look something like this

^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$

Actually checking if the email exists and doesn't bounce would mean sending an email and seeing what the result was. i.e. it bounced or it didn't. However it might not bounce for several hours or not at all and still not be a "real" email address. There are a number of services out there which purport to do this for you and would probably be paid for by you and quite frankly why bother to see if it is real?

It is good to check the user has not misspelt their email else they could enter it incorrectly, not realise it and then get hacked of with you for not replying. However if someone wants to add a bum email address there would be nothing to stop them creating it on hotmail or yahoo (or many other places) to gain the same end.

So do the regular expression and validate the structure but forget about validating against a service.

I want to handle passing multiple lists, integer values and strings.

Helpful link => How to pass a Bash variable to Python?

def main(args):
    my_args = []
    for arg in args:
        if arg.startswith("[") and arg.endswith("]"):
            arg = arg.replace("[", "").replace("]", "")
            my_args.append(arg.split(","))
        else:
            my_args.append(arg)

    print(my_args)


if __name__ == "__main__":
    import sys
    main(sys.argv[1:])

Order is not important. If you want to pass a list just do as in between "[" and "] and seperate them using a comma.

Then,

python test.py my_string 3 "[1,2]" "[3,4,5]"

Output => ['my_string', '3', ['1', '2'], ['3', '4', '5']], my_args variable contains the arguments in order.

You probably want to have something like this:

this.sendRequest(...)
.map(...)
.catch((err) => {
//handle your error here
})

It highly depends also how do you use your service but this is the basic case.

This may help you.

Another solution when a file pretends another extension

I use php inside of var.js file with this .htaccess.

<Files var.js>
    AddType application/x-httpd-php .js
</Files>

Then I write php code in the .js file

<?php
// This is a `.js` file but works with php
echo "var js_variable = '$php_variable';";

When I got the MIME type warning on Chrome, I fixed it by adding a Content-Type header line in the .js(but php) file.

<?php
header('Content-Type: application/javascript');        // <- Add this line
// This is a `.js` file but works with php
...

A browser won't execute .js file because apache sends the Content-Type header of the file as application/x-httpd-php that is defined in .htaccess. That's a security reason. But apache won't execute php as far as htaccess commands the impersonation, it's necessary. So we need to overwrite apache's Content-Type header with the php function header(). I guess that apache stops sending its own header when php sends it instead of apache before.

int theArray[] = new int[20];
System.out.println(theArray.length);

you can implement in a xml file for this as follows:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@drawable/your_imagename_while_focused"/>
<item android:state_pressed="true" android:drawable="@drawable/your_imagename_while_pressed" />
<item android:drawable="@drawable/image_name_while_notpressed" />  //means normal
</selector>

now save this xml file in drawable folder and name it suppos abc.xml and set it as follows

 Button tiny = (Button)findViewById(R.id.tiny);
 tiny.setBackgroundResource(R.drawable.abc);

Hope it will help you. :)

There are several methods you could use that exist in the System.IO namespace:

Directory.GetLogicalDrives() // Returns an array of strings like "c:\"
Path.GetInvalidFileNameChars() // Returns an array of characters that cannot be used in a file name
Path.GetInvalidPathChars() // Returns an array of characters that cannot be used in a path.

As suggested you could then do this:

bool IsValidFilename(string testName) {
    string regexString = "[" + Regex.Escape(Path.GetInvalidPathChars()) + "]";
    Regex containsABadCharacter = new Regex(regexString);
    if (containsABadCharacter.IsMatch(testName)) {
        return false;
    }

    // Check for drive
    string pathRoot = Path.GetPathRoot(testName);
    if (Directory.GetLogicalDrives().Contains(pathRoot)) {
        // etc
    }

    // other checks for UNC, drive-path format, etc

    return true;
}

There is no way to auto adjust for background image size using CSS.

You can hack around it by measuring the background image on the server and then applying those attributes to the div, as others have mentioned.

You could also hack up some javascript to resize the div based on the image size (once the image has been downloaded) - this is basically the same thing.

If you need your div to auto-fit the image, I might ask why don't you just put an <img> tag inside your div?

New ways to align items right:

Grid:

.header {
        display:grid;
        grid-template-columns: 1fr auto;
    }

Demo

Bootstrap 4. Align right:

<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>

Demo

Make a list of all letters in the US English Alphabet, skipping a & b. "CDEFGHIJKLMNOPQRSTUVWXYZ". Open each of those drives with CreateFile e.g. CreateFile("\\.\C:"). If it does not return INVALID_HANDLE_VALUE then you got a 'good' drive. Next take that handle and run it through DeviceIoControl to get the Disk #. See my related answer for more details.

As of matplotlib 3.3, you can do this with plt.axline((x1, y1), (x2, y2)).

\r is a carriage return character; it tells your terminal emulator to move the cursor at the start of the line.

The cursor is the position where the next characters will be rendered.

So, printing a \r allows to override the current line of the terminal emulator.

Tom Zych figured why the output of your program is o world while the \r is at the end of the line and you don't print anything after that:

When your program exits, the shell prints the command prompt. The terminal renders it where you left the cursor. Your program leaves the cursor at the start of the line, so the command prompt partly overrides the line you printed. This explains why you seen your command prompt followed by o world.

The online compiler you mention just prints the raw output to the browser. The browser ignores control characters, so the \r has no effect.

See https://en.wikipedia.org/wiki/Carriage_return

Here is a usage example of \r:

#include <stdio.h>
#include <unistd.h>

int main()
{
        char chars[] = {'-', '\\', '|', '/'};
        unsigned int i;

        for (i = 0; ; ++i) {
                printf("%c\r", chars[i % sizeof(chars)]);
                fflush(stdout);
                usleep(200000);
        }

        return 0;
}

It repeatedly prints the characters - \ | / at the same position to give the illusion of a rotating | in the terminal.

In addition to running it with mvn exec:java, you can also run it with mvn exec:exec

mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath your.package.MainClass"

If you really don't want to run into lots of annoying errors (datediff and such can't be evaluated in DataTable.Select among other things and even if you do as suggested use DataTable.AsEnumerable you will have trouble evaluating DateTime fields) do the following:

1) Model Your Data (create a class with DataTable columns)

{
public string PersonId { get; set; }
public DateTime DateBorn { get; set; }
}

2) Add this helper class to your code

}
}

3) Easily convert your DataTable (dt) to a List of objects with following code:

List<Person> persons = Extensions.ToList<Person>(dt);

4) have fun using Linq without the annoying row.Field<type> bit you have to use when using AsEnumerable

Example

var personsBornOn1980 = persons.Where(x=>x.DateBorn.Year == 1980);

Andy E is correct that there is no HTML-based way to do this*; but if you are willing to use Flash, you can do it. The following works reliably on systems that have Flash installed. If your app needs to work on iPhone, then of course you'll need a fallback HTML-based solution.

* (Update 4/22/2013: HTML does now support this, in HTML5. See the other answers.)

Flash uploading also has other advantages -- Flash gives you the ability to show a progress bar as the upload of a large file progresses. (I'm pretty sure that's how Gmail does it, by using Flash behind the scenes, although I may be wrong about that.)

Here is a sample Flex 4 app that allows the user to pick a file, and then displays it:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark"

               creationComplete="init()">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:Button x="10" y="10" label="Choose file..." click="showFilePicker()" />
    <mx:Image id="myImage" x="9" y="44"/>
    <fx:Script>
        <![CDATA[
            private var fr:FileReference = new FileReference();

            // Called when the app starts.
            private function init():void
            {
                // Set up event handlers.
                fr.addEventListener(Event.SELECT, onSelect);
                fr.addEventListener(Event.COMPLETE, onComplete);
            }

            // Called when the user clicks "Choose file..."
            private function showFilePicker():void
            {
                fr.browse();
            }

            // Called when fr.browse() dispatches Event.SELECT to indicate
            // that the user has picked a file.
            private function onSelect(e:Event):void
            {
                fr.load(); // start reading the file
            }

            // Called when fr.load() dispatches Event.COMPLETE to indicate
            // that the file has finished loading.
            private function onComplete(e:Event):void
            {
                myImage.data = fr.data; // load the file's data into the Image
            }
        ]]>
    </fx:Script>
</s:Application>

Just quote the argument to echo:

( IFS=$'\n'; echo "${my_array[*]}" )

the sub shell helps restoring the IFS after use

I had the same problem while installing Brotli

ERROR

Failed building wheel for Brotli

I solved it by downloading the .whl file from here and installing it using the below command

C:\Users\{user_name}\Downloads>pip install Brotli-1.0.9-cp39-cp39-win_amd64.whl

A simple possibility (if you'd rather avoid REs) is

' '.join(mystring.split())

The split and join perform the task you're explicitly asking about -- plus, they also do the extra one that you don't talk about but is seen in your example, removing trailing spaces;-).

If you don't want to reinvent the wheel you may try plupload.com

Set focus: The framework will handled moving focus in response to user input. To force focus to a specific view, call requestFocus()

I wanted to implement myself this, i ended up reading the Wikipedia page on Great-circle distance formula, because no code was readable enough for me to use as basis.

C# example

    /// <summary>
    /// Calculates the distance between two locations using the Great Circle Distance algorithm
    /// <see cref="https://en.wikipedia.org/wiki/Great-circle_distance"/>
    /// </summary>
    /// <param name="first"></param>
    /// <param name="second"></param>
    /// <returns></returns>
    private static double DistanceBetween(GeoLocation first, GeoLocation second)
    {
        double longitudeDifferenceInRadians = Math.Abs(ToRadians(first.Longitude) - ToRadians(second.Longitude));

        double centralAngleBetweenLocationsInRadians = Math.Acos(
            Math.Sin(ToRadians(first.Latitude)) * Math.Sin(ToRadians(second.Latitude)) +
            Math.Cos(ToRadians(first.Latitude)) * Math.Cos(ToRadians(second.Latitude)) *
            Math.Cos(longitudeDifferenceInRadians));

        const double earthRadiusInMeters = 6357 * 1000;

        return earthRadiusInMeters * centralAngleBetweenLocationsInRadians;
    }

    private static double ToRadians(double degrees)
    {
        return degrees * Math.PI / 180;
    }

a {
    target-name: new;
    target-new: tab;
}

The target-new property specifies whether new destination links should open in a new window or in a new tab of an existing window.

Note: The target-new property only works if the target-name property creates a new tab or a new window.

Use git filter-branch with an env filter that sets GIT_AUTHOR_DATE and GIT_COMMITTER_DATE for the specific hash of the commit you're looking to fix.

This will invalidate that and all future hashes.

Example:

If you wanted to change the dates of commit 119f9ecf58069b265ab22f1f97d2b648faf932e0, you could do so with something like this:

git filter-branch --env-filter \
    'if [ $GIT_COMMIT = 119f9ecf58069b265ab22f1f97d2b648faf932e0 ]
     then
         export GIT_AUTHOR_DATE="Fri Jan 2 21:38:53 2009 -0800"
         export GIT_COMMITTER_DATE="Sat May 19 01:01:01 2007 -0700"
     fi'

just past this on head of your php page. before any code on this should be the top code.

<?php
header("Content-Type: application/vnd.ms-word"); 
header("Expires: 0"); 
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("content-disposition: attachment;filename=Hawala.doc");

?>

this will convert all html to MSWORD, now you can customize it according to your client requirement.

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

Use the Out-File cmdlet

 Compare-Object ... | Out-File C:\filename.txt

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

echo "C:\Users\San.Tan\My Folder\project1" | sed -e 's/C:\\/mnt\/c\//;s/\\/\//g'

replaces

C:\Users\San.Tan\My Folder\project1

to

mnt/c/Users/San.Tan/My Folder/project1

in case someone needs to replace windows paths to Windows Subsystem for Linux(WSL) paths

I am not sure it would read better but you could do the following:

while any((not condition1, not condition2, val == -1)):
    val,something1,something2 = getstuff()

    if something1==10:
        condition1 = True

    if something2==20:
        condition2 = True

apache commons lang has a class SystemUtils.java you can use :

SystemUtils.IS_OS_LINUX
SystemUtils.IS_OS_WINDOWS

I had the same problem right now and i solved it. You must not need it anymore so I write for others:

if you use gvim on windows, you just add this in your _vimrc: $VIMRUNTIME/mswin.vim behave mswin

else just use imap...

As mentioned in a more recent answer, the preferred way is now simply:

const homedir = require('os').homedir();

[Original Answer]: Why not use the USERPROFILE environment variable on win32?

function getUserHome() {
  return process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'];
}

What you are looking for is merging.

git merge master

With pull you fetch changes from a remote repository and merge them into the current branch.

Use base R. Function runif generates uniformly distributed values from 0 to 1.By varying cutoff value (train.size in example below), you will always have approximately the same percentage of random records below the cutoff value.

data(mtcars)
set.seed(123)

#desired proportion of records in training set
train.size<-.7
#true/false vector of values above/below the cutoff above
train.ind<-runif(nrow(mtcars))<train.size

#train
train.df<-mtcars[train.ind,]


#test
test.df<-mtcars[!train.ind,]

Windows 10

This is basically @lengxuehx's answer, but updated for Win 10, and it assumes your bash installation is from Git Bash for Windows from git's official downloads.

cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

I ended up using this after I lost my context-menu items for Git Bash as my command to run from the registry settings. In case you're curious about that, I did this:

1. Create a new key called Bash in the shell key at HKEY_CLASSES_ROOT\Directory\Background\shell
2. Add a string value to Icon (not a new key!) that is the full path to your git-bash.exe, including the git-bash.exe part. You might need to wrap this in quotes.
3. Edit the default value of Bash to the text you want to use in the context menu
4. Add a sub-key to Bash called command
5. Modify command's default value to cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

Then you should be able to close the registry and start using Git Bash from anywhere that's a real directory. For example, This PC is not a real directory.

The original request has been answered already.

However, I am posting the below answer for those who might be looking for generic transliteration code to transliterate any charset to Latin/English in Java.

Naive meaning of tranliteration: Translated string in it's final form/target charset sounds like the string in it's original form. If we want to transliterate any charset to Latin(English alphabets), then ICU4(ICU4J library in java ) will do the job.

Here is the code snippet in java:

    import com.ibm.icu.text.Transliterator; //ICU4J library import

    public static String TRANSLITERATE_ID = "NFD; Any-Latin; NFC";
    public static String NORMALIZE_ID = "NFD; [:Nonspacing Mark:] Remove; NFC";

    /**
    * Returns the transliterated string to convert any charset to latin.
    */
    public static String transliterate(String input) {
        Transliterator transliterator = Transliterator.getInstance(TRANSLITERATE_ID + "; " + NORMALIZE_ID);
        String result = transliterator.transliterate(input);
        return result;
    }

Try this:

<asp:HiddenField ID="0858674_h" Value="0" runat="server" />

var test = $(this).find('[id*="_h"').val();

Well, I can think of a CSS hack that will resolve this issue.

You could add the following line in your CSS file:

* html .blog_list div.postbody img { width:75px; height: SpecifyHeightHere; } 

The above code will only be seen by IE6. The aspect ratio won't be perfect, but you could make it look somewhat normal. If you really wanted to make it perfect, you would need to write some javascript that would read the original picture width, and set the ratio accordingly to specify a height.

Swift 4+: I was using this for soft keyboard design, and for some reason the UIDevice.current.orientation.isLandscape method kept telling me it was Portrait, so here's what I used instead:

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    if(size.width > self.view.frame.size.width){
        //Landscape
    }
    else{
        //Portrait
    }
}

I think you need to use for example:

aws ecs list-container-instances --cluster default --region us-east-1

This depends of your region of course.

For ASP.NET Core You can use asp-route-* attribute:

<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">

An example: Imagine that you have a Vehicle Controller with actions

Index

Details

Edit

and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.

//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
     ..............
     ..............
     public string ReturnUrl {get;set;}
}



Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>

Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>

Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
        <div class="box-footer">
            <a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
            <button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
        </div>
    </form>

In your controller:

// GET: Vehicle/Edit/5
    public ActionResult Edit(int id,string previous)
    {
            var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
            var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
    //or by this code if you are not use automapper
    var viewModel = new VehicleViewModel();

    if (!string.IsNullOrWhiteSpace(previous)
                viewModel.ReturnUrl = previous;
            else
                viewModel.ReturnUrl = "Index";
            return View(viewModel);
        }



[HttpPost]
    public IActionResult Edit(VehicleViewModel model, string previous)
    {
            if (!string.IsNullOrWhiteSpace(previous))
                model.ReturnUrl = previous;
            else
                model.ReturnUrl = "Index";
            ............. 
            .............
            return RedirectToAction(model.ReturnUrl);
    }

Even if above solutions don't work, check permissions to destination file of aws ec2 instance. May be you can try with- sudo chmod 777 -R destinationFolder/*

fork() semantics are necessary where the child needs access to the actual memory state of the parent as of the instant fork() is called. I have a piece of software which relies on the implicit mutex of memory copying as of the instant fork() is called, which makes threads impossible to use. (This is emulated on modern *nix platforms via copy-on-write/update-memory-table semantics.)

The closest that exists on Windows as a syscall is CreateProcess. The best that can be done is for the parent to freeze all other threads during the time that it is copying memory over to the new process's memory space, then thaw them. Neither the Cygwin frok [sic] class nor the Scilab code that Eric des Courtis posted does the thread-freezing, that I can see.

Also, you probably shouldn't use the Zw* functions unless you're in kernel mode, you should probably use the Nt* functions instead. There's an extra branch that checks whether you're in kernel mode and, if not, performs all of the bounds checking and parameter verification that Nt* always do. Thus, it's very slightly less efficient to call them from user mode.

I was also faced by the posted issue when I used python 2.7. It is working very fine with python 3.4

To make it work in python 2.7 I have added the __metaclass__ = type attribute at the top of my program and it worked.

__metaclass__ : It eases the transition from old-style classes and new-style classes.

Given this is such a common issue, geronto-posting:

    if(UNIX AND NOT APPLE)
        set(LINUX TRUE)
    endif()

    # if(NOT LINUX) should work, too, if you need that
    if(LINUX) 
        message(STATUS ">>> Linux")
        # linux stuff here
    else()
        message(STATUS ">>> Not Linux")
        # stuff that should happen not on Linux 
    endif()

CMake boolean logic docs

CMake platform names, etc.

The problem seems to be a mis-placed ). In your sample you have the % outside of the print(), you should move it inside:

Use this:

print("%s. %s appears %s times." % (str(i), key, str(wordBank[key])))

In case you need to know if a checkbox is checked in pure javascript you should use this code .

let checkbox =document.getElementById('myCheckboxId');
if(checkbox.checked) {
    alert("element is checked");
} else {
    alert("element is  ot checked");
}

The instructions in the official Python documentation worked for me: https://docs.python.org/2/using/windows.html#executing-scripts

1. Launch a command prompt.

2. Associate the correct file group with .py scripts:

   assoc .py=Python.File
   

Redirect all Python files to the new executable:

    ftype Python.File=C:\Path\to\pythonw.exe "%1" %*

The example shows how to associate the .py extension with the .pyw executable, but it works if you want to associate the .py extension with the Anaconda Python executable. You need administrative rights. The name "Python.File" could be anything, you just have to make sure is the same name in the ftype command. When you finish and before you try double-clicking the .py file, you must change the "Open with" in the file properties. The file type will be now ".py" and it is opened with the Anaconda python.exe.

If anyone else had problems doing two transitions at once, here's what I did. I needed text to come from top to bottom on page load.

HTML

<body class="existing-class-name" onload="document.body.classList.add('loaded')">

HTML

<div class="image-wrapper">
    <img src="db-image.jpg" alt="db-image-name">
    <span class="text-over-image">DB text</span>
</div>

CSS

.text-over-image {
    position: absolute;
    background-color: rgba(110, 186, 115, 0.8);
    color: #eee;
    left: 0;
    width: 100%;
    padding: 10px;
    opacity: 0;
    bottom: 100%;
    -webkit-transition: opacity 2s, bottom 2s;
    -moz-transition: opacity 2s, bottom 2s;
    -o-transition: opacity 2s, bottom 2s;
    transition: opacity 2s, bottom 2s;
}

body.loaded .text-over-image {
    bottom: 0;
    opacity: 1;
}

Don't know why I kept trying to use 2 transition declarations in 1 selector and (not really) thinking it would use both.

answer = True
myvar = "the answer is " + str(answer)

or

myvar = "the answer is %s" % answer

I think this is very easy to do with very few lines. here is my solution

.buttonToLink{
   background: none;
   border: none;
   color: red
}

.buttonToLink:hover{
   background: none;
   text-decoration: underline;
}

<button  class="buttonToLink">A simple link button</button>

Or you can extract this method to some strategy object. In this case you can easily test extracted class and don't make method public or some magic with reflection/bytecode.

File -> Export -> Web -> WAR file

OR in Kepler follow as shown below :

Using only native JS, something like this will work:

a = [{ value:"4a55eff3-1e0d-4a81-9105-3ddd7521d642", display:"Jamsheer"}, { value:"644838b3-604d-4899-8b78-09e4799f586f", display:"Muhammed"}, { value:"b6ee537a-375c-45bd-b9d4-4dd84a75041d", display:"Ravi"}, { value:"e97339e1-939d-47ab-974c-1b68c9cfb536", display:"Ajmal"},  { value:"a63a6f77-c637-454e-abf2-dfb9b543af6c", display:"Ryan"}]_x000D_
b = [{ value:"4a55eff3-1e0d-4a81-9105-3ddd7521d642", display:"Jamsheer", $$hashKey:"008"}, { value:"644838b3-604d-4899-8b78-09e4799f586f", display:"Muhammed", $$hashKey:"009"}, { value:"b6ee537a-375c-45bd-b9d4-4dd84a75041d", display:"Ravi", $$hashKey:"00A"}, { value:"e97339e1-939d-47ab-974c-1b68c9cfb536", display:"Ajmal", $$hashKey:"00B"}]_x000D_
_x000D_
function comparer(otherArray){_x000D_
  return function(current){_x000D_
    return otherArray.filter(function(other){_x000D_
      return other.value == current.value && other.display == current.display_x000D_
    }).length == 0;_x000D_
  }_x000D_
}_x000D_
_x000D_
var onlyInA = a.filter(comparer(b));_x000D_
var onlyInB = b.filter(comparer(a));_x000D_
_x000D_
result = onlyInA.concat(onlyInB);_x000D_
_x000D_
console.log(result);

first, you have to create a handler.

var specialElementHandlers = {
    '#editor': function(element, renderer){
        return true;
    }
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
    'width': 170, 
    'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

The spot you have commented as // Code to trig on item change... will only trigger when the collection object gets changed, such as when it gets set to a new object, or set to null.

With your current implementation of TrulyObservableCollection, to handle the property changed events of your collection, register something to the CollectionChanged event of MyItemsSource

public MyViewModel()
{
    MyItemsSource = new TrulyObservableCollection<MyType>();
    MyItemsSource.CollectionChanged += MyItemsSource_CollectionChanged;

    MyItemsSource.Add(new MyType() { MyProperty = false });
    MyItemsSource.Add(new MyType() { MyProperty = true});
    MyItemsSource.Add(new MyType() { MyProperty = false });
}


void MyItemsSource_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
    // Handle here
}

Personally I really don't like this implementation. You are raising a CollectionChanged event that says the entire collection has been reset, anytime a property changes. Sure it'll make the UI update anytime an item in the collection changes, but I see that being bad on performance, and it doesn't seem to have a way to identify what property changed, which is one of the key pieces of information I usually need when doing something on PropertyChanged.

I prefer using a regular ObservableCollection and just hooking up the PropertyChanged events to it's items on CollectionChanged. Providing your UI is bound correctly to the items in the ObservableCollection, you shouldn't need to tell the UI to update when a property on an item in the collection changes.

public MyViewModel()
{
    MyItemsSource = new ObservableCollection<MyType>();
    MyItemsSource.CollectionChanged += MyItemsSource_CollectionChanged;

    MyItemsSource.Add(new MyType() { MyProperty = false });
    MyItemsSource.Add(new MyType() { MyProperty = true});
    MyItemsSource.Add(new MyType() { MyProperty = false });
}

void MyItemsSource_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
    if (e.NewItems != null)
        foreach(MyType item in e.NewItems)
            item.PropertyChanged += MyType_PropertyChanged;

    if (e.OldItems != null)
        foreach(MyType item in e.OldItems)
            item.PropertyChanged -= MyType_PropertyChanged;
}

void MyType_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "MyProperty")
        DoWork();
}

Example 4 columns of span3. For other span widths use new width = old width + gutter size. Use media queries to make it responsive.

css:

    <style type="text/css">
    @media (min-width: 1200px) 
    {   
        .nogutter .span3
        {
            margin-left: 0px; width:300px;
        }   
    }
    @media (min-width: 980px) and (max-width: 1199px) 
    { 
        .nogutter .span3
        {
            margin-left: 0px; width:240px;
        }   
    }
    @media (min-width: 768px) and (max-width: 979px) 
    { 
        .nogutter .span3
        {   
            margin-left: 0px; width:186px;
        }   
    }
    </style>

html:

<div class="container">
<div class="row">

Here's one I wrote... uses arcs instead of quadratic curves for better control over radius. Also, it leaves the stroking and filling up to you

    /* Canvas 2d context - roundRect
 *
 * Accepts 5 parameters, the start_x and start_y points, the end_x and end_y points, and the radius of the corners
 * 
 * No return value
 */

CanvasRenderingContext2D.prototype.roundRect = function(sx,sy,ex,ey,r) {
    var r2d = Math.PI/180;
    if( ( ex - sx ) - ( 2 * r ) < 0 ) { r = ( ( ex - sx ) / 2 ); } //ensure that the radius isn't too large for x
    if( ( ey - sy ) - ( 2 * r ) < 0 ) { r = ( ( ey - sy ) / 2 ); } //ensure that the radius isn't too large for y
    this.beginPath();
    this.moveTo(sx+r,sy);
    this.lineTo(ex-r,sy);
    this.arc(ex-r,sy+r,r,r2d*270,r2d*360,false);
    this.lineTo(ex,ey-r);
    this.arc(ex-r,ey-r,r,r2d*0,r2d*90,false);
    this.lineTo(sx+r,ey);
    this.arc(sx+r,ey-r,r,r2d*90,r2d*180,false);
    this.lineTo(sx,sy+r);
    this.arc(sx+r,sy+r,r,r2d*180,r2d*270,false);
    this.closePath();
}

Here is an example:

var _e = document.getElementById('#my_canvas');
var _cxt = _e.getContext("2d");
_cxt.roundRect(35,10,260,120,20);
_cxt.strokeStyle = "#000";
_cxt.stroke();

Java 7 one line solution

List<String> lines = Files.readAllLines(Paths.get("file"), StandardCharsets.UTF_8);

or

 String text = new String(Files.readAllBytes(Paths.get("file")), StandardCharsets.UTF_8);

Hide #categories initially

#categories {
    display: none;
}

and then, using JQuery UI, animate the Menu slowly

var duration = 'slow';

$('#cat_icon').click(function () {
    $('#cat_icon').hide(duration, function() {
        $('#categories').show('slide', {direction: 'left'}, duration);});
});
$('.panel_title').click(function () {
    $('#categories').hide('slide', {direction: 'left'}, duration, function() {
        $('#cat_icon').show(duration);});
});

JSFiddle

You can use any time in milliseconds as well

var duration = 2000;

If you want to hide on class='panel_item' too, select both panel_title and panel_item

$('.panel_title,.panel_item').click(function () {
    $('#categories').hide('slide', {direction: 'left'}, duration, function() {
        $('#cat_icon').show(duration);});
});

I recommend using .htaccess. You only need to add:

DirectoryIndex home.php

or whatever page name you want to have for it.

EDIT: basic htaccess tutorial.

1) Create .htaccess file in the directory where you want to change the index file.

• no extension
• . in front, to ensure it is a "hidden" file

Enter the line above in there. There will likely be many, many other things you will add to this (AddTypes for webfonts / media files, caching for headers, gzip declaration for compression, etc.), but that one line declares your new "home" page.

2) Set server to allow reading of .htaccess files (may only be needed on your localhost, if your hosting servce defaults to allow it as most do)

Assuming you have access, go to your server's enabled site location. I run a Debian server for development, and the default site setup is at /etc/apache2/sites-available/default for Debian / Ubuntu. Not sure what server you run, but just search for "sites-available" and go into the "default" document. In there you will see an entry for Directory. Modify it to look like this:

<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

Then restart your apache server. Again, not sure about your server, but the command on Debian / Ubuntu is:

sudo service apache2 restart

Technically you only need to reload, but I restart just because I feel safer with a full refresh like that.

Once that is done, your site should be reading from your .htaccess file, and you should have a new default home page! A side note, if you have a sub-directory that runs a site (like an admin section or something) and you want to have a different "home page" for that directory, you can just plop another .htaccess file in that sub-site's root and it will overwrite the declaration in the parent.

Example fetch with authorization header:

fetch('URL_GOES_HERE', { 
   method: 'post', 
   headers: new Headers({
     'Authorization': 'Basic '+btoa('username:password'), 
     'Content-Type': 'application/x-www-form-urlencoded'
   }), 
   body: 'A=1&B=2'
 });

I'm on Mac OS 10.6.8

The easiest solution works for me is simply put in

$ export JAVA_HOME=$(/usr/libexec/java_home)

To test whether it works, put in

$ echo $JAVA_HOME

it shows

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

you can also test

$ which java

You can use PropertyConfigurator to load your log4j.properties wherever it is located in the disk.

Example:

Logger logger = Logger.getLogger(this.getClass());
String log4JPropertyFile = "C:/this/is/my/config/path/log4j.properties";
Properties p = new Properties();

try {
    p.load(new FileInputStream(log4JPropertyFile));
    PropertyConfigurator.configure(p);
    logger.info("Wow! I'm configured!");
} catch (IOException e) {
    //DAMN! I'm not....

}

If you have an XML Log4J configuration, use DOMConfigurator instead.

The simplest approach is to use a multitouch JavaScript library like Hammer.js. Then you can write code like:

canvas
    .hammer({prevent_default: true})
    .bind('doubletap', function(e) { // And double click
        // Zoom-in
    })
    .bind('dragstart', function(e) { // And mousedown
        // Get ready to drag
    })
    .bind('drag', function(e) { // And mousemove when mousedown
        // Pan the image
    })
    .bind('dragend', function(e) { // And mouseup
        // Finish the drag
    });

And you can keep going. It supports tap, double tap, swipe, hold, transform (i.e., pinch) and drag. The touch events also fire when equivalent mouse actions happen, so you don't need to write two sets of event handlers. Oh, and you need the jQuery plugin if you want to be able to write in the jQueryish way as I did.

The fact that a class implements Comparable means that you can take two objects from that class and compare them. Some classes, like certain collections (sort function in a collection) that keep objects in order rely on them being comparable (in order to sort you need to know which object is the "biggest" and so forth).

By default Windows defines the following prefix that is available to everyone: http://+:80/Temporary_Listen_Addresses/

So you can register your HttpListener via:

Prefixes.Add("http://+:80/Temporary_Listen_Addresses/" + Guid.NewGuid().ToString("D") + "/";

This sometimes causes problems with software such as Skype which will try to utilise port 80 by default.

Spent a few hours facing this issue this morning. I am likely to be the least technical person on these forums. Like the requester, I endured every reminder to set %JAVA_HOME%, biting my tongue each time I saw this non luminary advice. Finally I pondered whether my laptop's JRE was versions ahead of my JDK (as JREs are regularly updated automatically) and I installed the latest JDK. The difference was minor, emanating from a matter of weeks of different versions. I started with this error on jdk v 1.0865. The JRE was 1.0866. After installation, I had jdk v1.0874 and the equivalent JRE. At that point, I directed the Eclipse JRE to focus on my JDK and all was well. My println of java.home even reflected the correct JRE.

So much feedback repeated the wrong responses. I would strongly request that people read the feedback from others to avoid useless redundancy. Take care all, SG

The best way to do this in my opinion is to use python's itertools package.

>>>import itertools
>>>l1 = [1,2,3]
>>>l2 = [10,20,30]
>>>[l*2 for l in itertools.chain(*[l1,l2])]
[2, 4, 6, 20, 40, 60]

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

Try this:

select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;

Look at my code, it does the job for me

$( '#formId' )
  .submit( function( e ) {
    $.ajax( {
      url: 'FormSubmitUrl',
      type: 'POST',
      data: new FormData( this ),
      processData: false,
      contentType: false
    } );
    e.preventDefault();
  } );

I had a similar problem and solved it using list...not sure if this will help or not

classes = list(unique_labels(y_true, y_pred))

It was an Eclipse problem. When I tried to build it from the command line using

mvn package

it worked fine.

The solution is isblank(cell)=false

The tutorial ANGULAR.JS: NG-SELECT AND NG-OPTIONS helped me solve the problem:

<select id="countryId"
  class="form-control"
  data-ng-model="entity.countryId"
  ng-options="value.dataValue as value.dataText group by value.group for value in countries"></select>

Give the following command:

svn resolved <filename or directory that gives trouble>

While creating a fragment transaction, make sure to add the following code.

// Replace whatever is in the fragment_container view with this fragment, 
// and add the transaction to the back stack 
transaction.replace(R.id.fragment_container, newFragment); 
transaction.addToBackStack(null); 

Also make sure, to commit the transaction after adding it to backstack

A comparison between the different Visual Studio Express editions can be found at Visual Studio Express (archive.org link). The difference between Windows and Windows Desktop is that with the Windows edition you can build Windows Store Apps (using .NET, WPF/XAML) while the Windows Desktop edition allows you to write classic Windows Desktop applications. It is possible to install both products on the same machine.

Visual Studio Express 2010 allows you to build Windows Desktop applications. Writing Windows Store applications is not possible with this product.

For learning I would suggest Notepad and the command line. While an IDE provides significant productivity enhancements to professionals, it can be intimidating to a beginner. If you want to use an IDE nevertheless I would recommend Visual Studio Express 2013 for Windows Desktop.

Just a note, FishEye (and a lot of other Atlassian products) have a $10 Starter Editions, which in the case of FishEye gives you 5 repositories and access for up to 10 committers. The money goes to charity in this case.

www.atlassian.com/starter

if( myVariable ) 
{ 
    //mayVariable is not : 
    //null 
    //undefined 
    //NaN 
    //empty string ("") 
    //0 
    //false 
}

yourDGV.Rows.Add(column1,column2...columnx); //add a row to a dataGridview
yourDGV.Rows[rowindex].Cells[Cell/Columnindex].value = yourvalue; //edit the value

you can also create a new row and then add it to the DataGridView like this:

DataGridViewRow row = new DataGridViewRow();
row.Cells[Cell/Columnindex].Value = yourvalue;
yourDGV.Rows.Add(row);

NW.js

(Previously known as node-webkit)

I would suggest NW.js if you are familiar with Node or experienced with JavaScript.

NW.js is an app runtime based on Chromium and node.js.

Features

• Apps written in modern HTML5, CSS3, JS and WebGL
• Complete support for Node.js APIs and all its third party modules.
• Good performance: Node and WebKit run in the same thread: Function calls are made straightforward; objects are in the same heap and can just reference each other
• Easy to package and distribute apps
• Available on Linux, Mac OS X and Windows

You can find the NW.js repo here, and a good introduction to NW.js here. If you fancy learning Node.js I would recommend this SO post with a lot of good links.

If you need to mutate the dictionary while enumerating:

for (NSString* key in xyz.allKeys) {
    [xyz setValue:[NSNumber numberWithBool:YES] forKey:key];
}

ES6 of the day here;

const json_getAllKeys = data => (
  data.reduce((keys, obj) => (
    keys.concat(Object.keys(obj).filter(key => (
      keys.indexOf(key) === -1))
    )
  ), [])
)

And yes it can be written in very long one line;

const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])

EDIT: Returns all first order keys if the input is of type array of objects

You could do this with generics trick, but it still is vulnerable to what Jon Skeet wrote:

public interface IHasDefaultConstructor<T> where T : IHasDefaultConstructor<T>, new()
{
}

Class that implements this interface must have parameterless constructor:

public class A : IHasDefaultConstructor<A> //Notice A as generic parameter
{
    public A(int a) { } //compile time error
}

Without any plugins:

You just need to enable highlight: (Idea v.2016, 2017 and 2018, previous versions may have same or similar settings)

File -> Settings -> Editor -> Inspections -> Java -> Serialization issues -> Serializable class without 'serialVersionUID' - set flag and click 'OK'. (For Macs, Settings is under IntelliJ IDEA -> Preferences...)

Now, if your class implements Serializable, you will see highlight and alt+Enter on class name will ask you to generate private static final long serialVersionUID.

UPD: a faster way to find this setting - you might use hotkey Ctrl+Shift+A (find action), type Serializable class without 'serialVersionUID' - the first is the one.

You can use WebClient to download the html for any url. Once you have the html, you can use a third-party library like HtmlAgilityPack to lookup values in the html as in below code -

public static string GetInnerHtmlFromDiv(string url)
    {
        string HTML;
        using (var wc = new WebClient())
        {
            HTML = wc.DownloadString(url);
        }
        var doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(HTML);
        
        HtmlNode element = doc.DocumentNode.SelectSingleNode("//div[@id='<div id here>']");
        if (element != null)
        {
            return element.InnerHtml.ToString();
        }   
        return null;            
    }

This worked for me:

byte[] bfoo = (byte[])foo;

foo is an Object that I'm 100% certain that is a byte array.

Since JsonSerializer is deprecated in .Net 4.0+ I used http://www.newtonsoft.com/json to solve this issue.

NuGet- > Install-Package Newtonsoft.Json

download the library Gradle:

compile 'com.google.code.gson:gson:2.8.2'

To use the library in a method.

Gson gson = new Gson();

//transform a java object to json
System.out.println("json =" + gson.toJson(Object.class).toString());

//Transform a json to java object
String json = string_json;
List<Object> lstObject = gson.fromJson(json_ string, Object.class);

Re-review the Android Activity Lifecycle reference. There is a nice picture, and the table showing what methods get called. reference Link google

https://developer.android.com/reference/android/app/Activity.html

If you are unable to get rid of extra xmlns attributes for each element, when serializing to xml from generated classes (e.g.: when xsd.exe was used), so you have something like:

<manyElementWith xmlns="urn:names:specification:schema:xsd:one" />

then i would share with you what worked for me (a mix of previous answers and what i found here)

explicitly set all your different xmlns as follows:

Dim xmlns = New XmlSerializerNamespaces()
xmlns.Add("one", "urn:names:specification:schema:xsd:one")
xmlns.Add("two",  "urn:names:specification:schema:xsd:two")
xmlns.Add("three",  "urn:names:specification:schema:xsd:three")

then pass it to the serialize

serializer.Serialize(writer, object, xmlns);

you will have the three namespaces declared in the root element and no more needed to be generated in the other elements which will be prefixed accordingly

<root xmlns:one="urn:names:specification:schema:xsd:one" ... />
   <one:Element />
   <two:ElementFromAnotherNameSpace /> ...

If you're running it in Eclipse, check the jars of any projects added to the build path; or do control-shift-T and scan for multiple jars matching the same namespace. Then remove redundant or outdated jars from the project's build path.

Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.

This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.

NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.

NOTE: The only sandbox setting available is now IFRAME. I you want to use an onsubmit attribute in the beginning form tag: <form onsubmit="myFunctionName()">, it may cause the form to disappear from the screen after the form submission.

If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.

If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault(); to your code in the submit event handler function. Or you'll need to use the google.script.run client side API.

A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.

This example shows an upload form with Google Apps Script HTML Service.

What You Need

• Google Account
• Google Drive
• Google Apps Script - also called Google Script

Google Apps Script

There are various ways to end up at the Google Apps Script code editor.

• Load Apps Script directly from the web address: https://script.google.com
• Open a Google Sheet first, then open Apps Script
• Go to your Google Drive, then Open Apps Script: https://drive.google.com/drive/#my-drive
• Go to your Google Drive, then click on an Apps Script project file
• Open Apps Script from Google Docs
• etc

I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.

Apps Script Overview

This example is a "Stand Alone" app with HTML Service.

HTML Service - Create a web app using HTML, CSS and Javascript

Google Apps Script only has two types of files inside of a Project:

• Script
• HTML

Script files have a .gs extension. The .gs code is a server side code written in JavaScript, and a combination of Google's own API.

• Copy and Paste the following code

• Save It

• Create the first Named Version

• Publish it

• Set the Permissions

  and you can start using it.

Start by:

• Create a new Blank Project in Apps Script
• Copy and Paste in this code:

Upload a file with HTML Service:

Code.gs file (Created by Default)

//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to

function doGet(e) {
  return HtmlService.createTemplateFromFile('Form')
    .evaluate() // evaluate MUST come before setting the Sandbox mode
    .setTitle('Name To Appear in Browser Tab')
    .setSandboxMode();//Defaults to IFRAME which is now the only mode available
}

function processForm(theForm) {
  var fileBlob = theForm.picToLoad;
  
  Logger.log("fileBlob Name: " + fileBlob.getName())
  Logger.log("fileBlob type: " + fileBlob.getContentType())
  Logger.log('fileBlob: ' + fileBlob);

  var fldrSssn = DriveApp.getFolderById(Your Folder ID);
    fldrSssn.createFile(fileBlob);
    
  return true;
}

Create an html file:

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <h1 id="main-heading">Main Heading</h1>
    <br/>
    <div id="formDiv">

      <form id="myForm">
    
        <input name="picToLoad" type="file" /><br/>
        <input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
          
      </form>
    </div>


  <div id="status" style="display: none">
  <!-- div will be filled with innerHTML after form submission. -->
  Uploading. Please wait...
</div>

</body>
<script>

function picUploadJs(frmData) {

  document.getElementById('status').style.display = 'inline';

  google.script.run
    .withSuccessHandler(updateOutput)
    .processForm(frmData)
};
  // Javascript function called by "submit" button handler,
  // to show results.
  
  function updateOutput() {
  
    var outputDiv = document.getElementById('status');
    outputDiv.innerHTML = "The File was UPLOADED!";
  }

</script>
</html>

This is a full working example. It only has two buttons and one <div> element, so you won't see much on the screen. If the .gs script is successful, true is returned, and an onSuccess function runs. The onSuccess function (updateOutput) injects inner HTML into the div element with the message, "The File was UPLOADED!"

• Save the file, give the project a name
• Using the menu: File, Manage Version then Save the first Version
• Publish, Deploy As Web App then Update

When you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.

The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.

Another example of using the HTML Service can be seen at this link here on StackOverflow:

File Upload with HTML Service

NOTES about deprecated UI Service:

There is a difference between the UI Service, and the Ui getUi() method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.

Google Documentation - UI Service

Even though the UI Service is deprecated, there is a getUi() method of the spreadsheet class to add custom menus, which is NOT deprecated:

Spreadsheet Class - Get UI method

I mention this because it could be confusing because they both use the terminology UI.

The UI method returns a Ui return type.

You can add HTML to a UI Service, but you can't use a <button>, <input> or <script> tag in the HTML with the UI Service.

Here is a link to a shared Apps Script Web App file with an input form:

Shared File - Contact Form

Your svn merge syntax is wrong.

You want to checkout a working copy of trunk and then use the svn merge --reintegrate option:

$ pwd
/home/user/project-trunk

$ svn update  # (make sure the working copy is up to date)
At revision <N>.

$ svn merge --reintegrate ^/project/branches/branch_1
--- Merging differences between repository URLs into '.':
U    foo.c
U    bar.c
 U   .

$ # build, test, verify, ...

$ svn commit -m "Merge branch_1 back into trunk!"
Sending        .
Sending        foo.c
Sending        bar.c
Transmitting file data ..
Committed revision <N+1>.

See the SVN book chapter on merging for more details.

Note that at the time it was written, this was the right answer (and was accepted), but things have moved on. See the answer of topek, and http://subversion.apache.org/docs/release-notes/1.8.html#auto-reintegrate

You can use something like this,

var element = document.getElementById("yourDivID");
window.scrollTo(0,element.offsetHeight);

I have found that using cabs(double), cabsf(float), cabsl(long double), __cabsf(float), __cabs(double), __cabsf(long double) is the solution

I just tried to make a transparent image with powerpoint after failing miserably with other online systems. I was successful. Amazing.

First I used word art to give me typefaces which convert well to PNG or JPEG. The ordinary text in powerpoint does not convert well. It gets fuzzy. Anyway, I typed in my words in white (my choice of colour as i wanted it against a navy blue background), arranged it how i wanted, then right clicked and selected format shape to remove lines, then shadow to set the transparency.

I took the transparency to 100%. It came out fine. i then right clicked to save as png. Opened the image with MS Picture manager and resized the image to my suiting. It did not come out with the powerpoint white background at all. Once resized, i dropped the image against my navy blue background and it was like magic.

Change *.cs to .cs in the excludefileslist.txt

It can be done this way as well

foreach (Company company in listofCompany.Where(d => d.Id = 1)).ToList())
                {
                    //do your stuff here
                    company.Id= 2;
                    company.Name= "Sample"
                }

I cracked open Reflector to have a look at this as there seems to be a bit of confusion about SortedList. It is in fact not a binary search tree, it is a sorted (by key) array of key-value pairs. There is also a TKey[] keys variable which is sorted in sync with the key-value pairs and used to binary search.

Here is some source (targeting .NET 4.5) to backup my claims.

Private members

// Fields
private const int _defaultCapacity = 4;
private int _size;
[NonSerialized]
private object _syncRoot;
private IComparer<TKey> comparer;
private static TKey[] emptyKeys;
private static TValue[] emptyValues;
private KeyList<TKey, TValue> keyList;
private TKey[] keys;
private const int MaxArrayLength = 0x7fefffff;
private ValueList<TKey, TValue> valueList;
private TValue[] values;
private int version;

SortedList.ctor(IDictionary, IComparer)

public SortedList(IDictionary<TKey, TValue> dictionary, IComparer<TKey> comparer) : this((dictionary != null) ? dictionary.Count : 0, comparer)
{
    if (dictionary == null)
    {
        ThrowHelper.ThrowArgumentNullException(ExceptionArgument.dictionary);
    }
    dictionary.Keys.CopyTo(this.keys, 0);
    dictionary.Values.CopyTo(this.values, 0);
    Array.Sort<TKey, TValue>(this.keys, this.values, comparer);
    this._size = dictionary.Count;
}

SortedList.Add(TKey, TValue) : void

public void Add(TKey key, TValue value)
{
    if (key == null)
    {
        ThrowHelper.ThrowArgumentNullException(ExceptionArgument.key);
    }
    int num = Array.BinarySearch<TKey>(this.keys, 0, this._size, key, this.comparer);
    if (num >= 0)
    {
        ThrowHelper.ThrowArgumentException(ExceptionResource.Argument_AddingDuplicate);
    }
    this.Insert(~num, key, value);
}

SortedList.RemoveAt(int) : void

public void RemoveAt(int index)
{
    if ((index < 0) || (index >= this._size))
    {
        ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument.index, ExceptionResource.ArgumentOutOfRange_Index);
    }
    this._size--;
    if (index < this._size)
    {
        Array.Copy(this.keys, index + 1, this.keys, index, this._size - index);
        Array.Copy(this.values, index + 1, this.values, index, this._size - index);
    }
    this.keys[this._size] = default(TKey);
    this.values[this._size] = default(TValue);
    this.version++;
}

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?

Interface does not implement the methods of another interface but just extends them. One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward and moveBack but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp, moveDown so in the end you have:

public interface IVehicle {
  bool moveForward(int x);
  bool moveBack(int x);
};

and airplane:

public interface IAirplane extends IVehicle {
  bool moveDown(int x);
  bool moveUp(int x);
};

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

I simply Renamed my Xcode file in Application folder to something else and renamed it back to Xcode.

Worked

In the project I'm working on, audit log also started from the very minimalistic design, like the one you described:

event ID
event date/time
event type
user ID
description

The idea was the same: to keep things simple.

However, it quickly became obvious that this minimalistic design was not sufficient. The typical audit was boiling down to questions like this:

Who the heck created/updated/deleted a record 
with ID=X in the table Foo and when?

So, in order to be able to answer such questions quickly (using SQL), we ended up having two additional columns in the audit table

object type (or table name)
object ID

That's when design of our audit log really stabilized (for a few years now).

Of course, the last "improvement" would work only for tables that had surrogate keys. But guess what? All our tables that are worth auditing do have such a key!

Try this piece of code, it should work too

<%
    //response.setContentType("Content-Type", "application/json"); // this will fail compilation
    response.setContentType("application/json"); //fixed
%>

$("form").validate().settings.ignore = "*";

Or

$("form").validate().cancelSubmit = true;

But without success in a custom required validator. For call a submit dynamically, i have created a fake hidden submit button with this code:

var btn = form.children('input.cancel.fakeSubmitFormButton');
if (btn.length === 0) {
    btn = $('<input name="FakeCancelSubmitButton" class="cancel fakeSubmitFormButton hide" type="submit" formnovalidate value="FakeCancelSubmitButton" />');
    form.append(btn);
}
btn.click();

Now skip the validation correctly :)

Just put the condition into the lambda itself, e.g.

animalMap.entrySet().stream()
        .forEach(
                pair -> {
                    if (pair.getValue() != null) {
                        myMap.put(pair.getKey(), pair.getValue());
                    } else {
                        myList.add(pair.getKey());
                    }
                }
        );

Of course, this assumes that both collections (myMap and myList) are declared and initialized prior to the above piece of code.

Update: using Map.forEach makes the code shorter, plus more efficient and readable, as Jorn Vernee kindly suggested:

    animalMap.forEach(
            (key, value) -> {
                if (value != null) {
                    myMap.put(key, value);
                } else {
                    myList.add(key);
                }
            }
    );

I/O is an operating system function. In many cases, the operating system won't pass typed character to a program until ENTER is pressed. This allows the user to modify the input (such as backspacing and retyping) before sending it to the program. For most purposes, this works well, presents a consistent interface to the user, and relieves the program from having to deal with this. In some cases, it's desirable for a program to get characters from keys as they are pressed.

The C library itself deals with files, and doesn't concern itself with how data gets into the input file. Therefore, there's no way in the language itself to get keys as they are pressed; instead, this is platform-specific. Since you haven't specified OS or compiler, we can't look it up for you.

Also, the standard output is normally buffered for efficiency. This is done by the C libraries, and so there is a C solution, which is to fflush(stdout); after each character written. After that, whether the characters are displayed immediately is up to the operating system, but all the OSes I'm familiar with will display the output immediately, so that's not normally a problem.

Just pressing F5 is not always working.

why?

Because your ISP is also caching web data for you.

Solution: Force Refresh.

Force refresh your browser by pressing CTRL + F5 in Firefox or Chrome to clear ISP cache too, instead of just pressing F5

You then can see 200 response instead of 304 in the browser F12 developer tools network tab.

Another trick is to add question mark ? at the end of the URL string of the requested page:

http://localhost:52199/Customers/Create?

The question mark will ensure that the browser refresh the request without caching any previous requests.

Additionally in Visual Studio you can set the default browser to Chrome in Incognito mode to avoid cache issues while developing, by adding Chrome in Incognito mode as default browser, see the steps (self illustrated):

No offense, but it's unclever to change class on-the-fly as it forces the CSS interpreter to recalculate the visual presentation of the entire web page.

The reason is that it is nearly impossible for the CSS interpreter to know if any inheritance or cascading could be changed, so the short answer is:

Never ever change className on-the-fly !-)

But usually you'll only need to change a property or two, and that is easily implemented:

function highlight(elm){
    elm.style.backgroundColor ="#345";
    elm.style.color = "#fff";
}

When you override the init you have also to call the init of the parent class

super(Num2, self).__init__(num)

Understanding Python super() with __init__() methods

I was able to get the full text (99,208 chars) out of a NVARCHAR(MAX) column by selecting (Results To Grid) just that column and then right-clicking on it and then saving the result as a CSV file. To view the result open the CSV file with a text editor (NOT Excel). Funny enough, when I tried to run the same query, but having Results to File enabled, the output was truncated using the Results to Text limit.

The work-around that @MartinSmith described as a comment to the (currently) accepted answer didn't work for me (got an error when trying to view the full XML result complaining about "The '[' character, hexadecimal value 0x5B, cannot be included in a name").

Edit: For a better approximation of Alejandro's answer, see below.

I know this is an old question, but wanted to add something to Alejandro's anwser: If you want a nice smoothed image without using py-sphviewer you can instead use np.histogram2d and apply a gaussian filter (from scipy.ndimage.filters) to the heatmap:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm
from scipy.ndimage.filters import gaussian_filter


def myplot(x, y, s, bins=1000):
    heatmap, xedges, yedges = np.histogram2d(x, y, bins=bins)
    heatmap = gaussian_filter(heatmap, sigma=s)

    extent = [xedges[0], xedges[-1], yedges[0], yedges[-1]]
    return heatmap.T, extent


fig, axs = plt.subplots(2, 2)

# Generate some test data
x = np.random.randn(1000)
y = np.random.randn(1000)

sigmas = [0, 16, 32, 64]

for ax, s in zip(axs.flatten(), sigmas):
    if s == 0:
        ax.plot(x, y, 'k.', markersize=5)
        ax.set_title("Scatter plot")
    else:
        img, extent = myplot(x, y, s)
        ax.imshow(img, extent=extent, origin='lower', cmap=cm.jet)
        ax.set_title("Smoothing with  $\sigma$ = %d" % s)

plt.show()

Produces:

The scatter plot and s=16 plotted on top of eachother for Agape Gal'lo (click for better view):

One difference I noticed with my gaussian filter approach and Alejandro's approach was that his method shows local structures much better than mine. Therefore I implemented a simple nearest neighbour method at pixel level. This method calculates for each pixel the inverse sum of the distances of the n closest points in the data. This method is at a high resolution pretty computationally expensive and I think there's a quicker way, so let me know if you have any improvements.

Update: As I suspected, there's a much faster method using Scipy's scipy.cKDTree. See Gabriel's answer for the implementation.

Anyway, here's my code:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm


def data_coord2view_coord(p, vlen, pmin, pmax):
    dp = pmax - pmin
    dv = (p - pmin) / dp * vlen
    return dv


def nearest_neighbours(xs, ys, reso, n_neighbours):
    im = np.zeros([reso, reso])
    extent = [np.min(xs), np.max(xs), np.min(ys), np.max(ys)]

    xv = data_coord2view_coord(xs, reso, extent[0], extent[1])
    yv = data_coord2view_coord(ys, reso, extent[2], extent[3])
    for x in range(reso):
        for y in range(reso):
            xp = (xv - x)
            yp = (yv - y)

            d = np.sqrt(xp**2 + yp**2)

            im[y][x] = 1 / np.sum(d[np.argpartition(d.ravel(), n_neighbours)[:n_neighbours]])

    return im, extent


n = 1000
xs = np.random.randn(n)
ys = np.random.randn(n)
resolution = 250

fig, axes = plt.subplots(2, 2)

for ax, neighbours in zip(axes.flatten(), [0, 16, 32, 64]):
    if neighbours == 0:
        ax.plot(xs, ys, 'k.', markersize=2)
        ax.set_aspect('equal')
        ax.set_title("Scatter Plot")
    else:
        im, extent = nearest_neighbours(xs, ys, resolution, neighbours)
        ax.imshow(im, origin='lower', extent=extent, cmap=cm.jet)
        ax.set_title("Smoothing over %d neighbours" % neighbours)
        ax.set_xlim(extent[0], extent[1])
        ax.set_ylim(extent[2], extent[3])
plt.show()

Result:

To expand upon nosklo's explanation:

a = {}
b = ['some', 'list']
a[b] = 'some' # this won't work
a[tuple(b)] = 'some' # this will, same as a['some', 'list']

The simplest solution is with copying files to shared printer.
Example in C#:

System.IO.File.Copy(inputFilePath, printerPath);

where:

• inputFilePath - path to ZPL file (special extension is not required);
• printerPath - path to shared(!) printer, for example: \127.0.0.1\zebraGX

I have 3 routines which work just fine, just select a cell in a table and run one of the subroutines

Sub ClearTable()
If Not ActiveCell.ListObject Is Nothing Then
    ActiveCell.ListObject.DataBodyRange.Rows.ClearContents
End If
End Sub

and Shrink Table to remove the databody range except from the headers and the first data row

Sub ShrinkTable()
If Not ActiveCell.ListObject Is Nothing Then
    ActiveCell.ListObject.DataBodyRange.Delete
End If
End Sub

and Delete Table to completely delete the table from the sheet

Sub DeleteTable()
If Not ActiveCell.ListObject Is Nothing Then
    ActiveCell.ListObject.Delete
End If
End Sub

You can use git stash. You have to specify --include-untracked, otherwise you'll end up with the original problem.

git stash --include-untracked

Then just drop the last entry in the stash

git stash drop

You can make a handy-dandy alias for that, and call it git discard for example:

git config --global alias.discard "! git stash -q --include-untracked && git stash drop -q"

Amazon provides a policy generator tool:

After that, you can enter the policy requirements for the bucket on the AWS console:

An alternative, and perhaps a not so good procedural coding one, is to send the "function name" to a script that then executes the function. For instance, with a login form, there is typically the login, forgotusername, forgotpassword, signin activities that are presented on the form as buttons or anchors. All of these can be directed to/as, say,

weblogin.php?function=login
weblogin.php?function=forgotusername
weblogin.php?function=forgotpassword
weblogin.php?function=signin

And then a switch statement on the receiving page does any prep work and then dispatches or runs the (next) specified function.

The proper way to set the root logging level is using the property logging.level.root. See documentation, which has been updated since this question was originally asked.

Example:

logging.level.root=WARN

In v1.43 is the ability to separately color the vertical rulers.

See issue Support multiple rulers with different colors - (in settings.json):

"editor.rulers": [
  {
    "column": 80,
    "color": "#ff00FF"
  },
  100,  // <- a ruler in the default color or as customized (with "editorRuler.foreground") at column 100
  {
    "column": 120,
    "color": "#ff0000"
  },
], 

Enum.GetName()

Format() is really just a wrapper around GetName() with some formatting functionality (or InternalGetValueAsString() to be exact). ToString() is pretty much the same as Format(). I think GetName() is best option since it's totally obvious what it does for anyone who reads the source.

CURL error code 7 (CURLE_COULDNT_CONNECT)

is very explicit ... it means Failed to connect() to host or proxy.

The following code would work on any system:

$ch = curl_init("http://google.com");    // initialize curl handle
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($ch);
print($data);

If you can not see google page then .. your URL is wrong or you have some firewall or restriction issue.

This is a little more concise and also allows you to have different dialog values etc based on different click events:

$('#click_link').live("click",function() {
    $("#popup").dialog({modal:true, width:500, height:800});

    $("#popup").dialog("open");

    return false;
});

My Hackie way to solve this was by modifying the swagger.go file in the echo-swagger package in my case:

At the bottom of the file update the window.onload function to include a requestInterceptor which correctly formats the token.

window.onload = function() {
  // Build a system
  const ui = SwaggerUIBundle({
  url: "{{.URL}}",
  dom_id: '#swagger-ui',
  validatorUrl: null,
  presets: [
    SwaggerUIBundle.presets.apis,
    SwaggerUIStandalonePreset
  ],
  plugins: [
    SwaggerUIBundle.plugins.DownloadUrl
  ,
  layout: "StandaloneLayout",
  requestInterceptor: (req) => {
    req.headers.Authorization = "Bearer " + req.headers.Authorization
  return req
  }
})

window.ui = ui

}

I went to File -> Project Structure -> Modules clicked on + and then import module found my root folder and selected it.

It worked.

I used the Sebastien Horin function getIp and request()->ip() (at global request), because to localhost the getIp function return null:

$this->getIp() ?? request()->ip();

The getIp function:

public function getIp(){
foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
    if (array_key_exists($key, $_SERVER) === true){
        foreach (explode(',', $_SERVER[$key]) as $ip){
            $ip = trim($ip); // just to be safe
            if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                return $ip;
            }
        }
    }
}

}

$('td').click(function() {
    var myCol = $(this).index();
    var $tr = $(this).closest('tr');
    var myRow = $tr.index();
});

The unwanted side effects of simple folder delete or installing over existing installation have been removed by a script written by Kyle Fuller - deintegrate and here is the proper workflow:

1. Install clean:

   $ sudo gem install cocoapods-clean
   

2. Run deintegrate in the folder of the project:

   $ pod deintegrate
   

3. Clean (this tool is no longer available):

   $ pod clean
   

4. Modify your podfile (delete the lines with the pods you don't want to use anymore) and run:

   $ pod install
   

Done.

var matches = [];
var searchEles = document.getElementById("myDiv").children;
for(var i = 0; i < searchEles.length; i++) {
    if(searchEles[i].tagName == 'SELECT' || searchEles.tagName == 'INPUT') {
        if(searchEles[i].id.indexOf('q1_') == 0) {
            matches.push(searchEles[i]);
        }
    }
}

Once again, I strongly suggest jQuery for such tasks:

$("#myDiv :input").hide(); // :input matches all input elements, including selects

I faced the same issue while creating the connection on SQLDeveloper "ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist"

Solution:

1.Update the listene.ora file to include the SID.

  SID_LIST_LISTENER =
    (SID_LIST =
      (SID_DESC =
        (SID_NAME = PLSExtProc)
        (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
        (PROGRAM = extproc)
      )
      (SID_DESC =
        (SID_NAME = CLRExtProc)
        (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
        (PROGRAM = extproc)
      )
      (SID_DESC =
        ((GLOBAL_DBNAME = XE.DB)
        ((ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
        ((SID_NAME = XE)
      )
    )

  LISTENER =
    (DESCRIPTION_LIST =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
        (ADDRESS = (PROTOCOL = TCP)(HOST = USMUMTBALAKDAS2.us.deloitte.com)(PORT = 1521))
      )
    )

  DEFAULT_SERVICE_LISTENER = (XE)

The Oraclexe directory may have the permission set to "ReadOnly", Change the directory/sub-directory permission to read/write and restart the listener services. Problem is solved.

You can also do it with the keyboard shortcut shown under the simulator menu bar (Hardware-> Home).

The shortcut is ?+?+H, but you need to hit H twice in a row for it to simulate the double press that shows the apps.

Well just a small change 'cause the above solution outputs

"I want anapple"

instead of

"I want an apple"

To get the output as

"I want an apple"

use the following modified code

var output = a.substr(0, position) + " " + b + a.substr(position);

Since your subdateshow is a VARCHAR column instead of the proper DATE, TIMESTAMP or DATETIME column you have to convert the string to date before you can use YEAR on it:

SELECT YEAR(STR_TO_DATE(subdateshow, "%m/%d/%Y")) from table

See http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_str-to-date

Looks like Facebook disabled passing parameters to the sharer.

We have changed the behavior of the sharer plugin to be consistent with other plugins and features on our platform.

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post from the url OG meta tags.

Here's the URL to the post: https://developers.facebook.com/x/bugs/357750474364812/

a = '123' if b else '456'

Consider this example:

bool isEqual = (23.42f == 23.42);

What is isEqual? 9 out of 10 people will say "It's true, of course" and 9 out of 10 people are wrong: https://rextester.com/RVL15906

That's because floating point numbers are no exact numeric representations.

Being binary numbers, they cannot even exactly represent all numbers that can be exact represented as decimal numbers. E.g. while 0.1 can be exactly represented as a decimal number (it is exactly the tenth part of 1), it cannot be represented using floating point because it is 0.00011001100110011... periodic as binary. 0.1 is for floating point what 1/3 is for decimal (which is 0.33333... as decimal)

The consequence is that calculations like 0.3 + 0.6 can result in 0.89999999999999991, which is not 0.9, albeit it's close to that. And thus the test 0.1 + 0.2 - 0.3 == 0.0 might fail as the result of the calculation may not be 0, albeit it will be very close to 0.

== is an exact test and performing an exact test on inexact numbers is usually not very meaningful. As many floating point calculations include rounding errors, you usually want your comparisons to also allow small errors and this is what the test code you posted is all about. Instead of testing "Is A equal to B" it tests "Is A very close to B" as very close is quite often the best result you can expect from floating point calculations.

I think you are right by saying that people cannot click half pixels, so personally, I would use rounded jQuery offset...

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);

1. The API you're interested in is the Product Advertising API (PA). It allows you programmatic access to search and retrieve product information from Amazon's catalog. If you're having trouble finding information on the API, that's because the web service has undergone two name changes in recent history: it was also known as ECS and AAWS.
2. The signature process you're referring to is the same HMAC signature that all of the other AWS services use for authentication. All that's required to sign your requests to the Product Advertising API is a function to compute a SHA-1 hash and and AWS developer key. For more information, see the section of the developer documentation on signing requests.
3. As far as I know, there is no support for retrieving RSS feeds of products or tags through PA. If anyone has information suggesting otherwise, please correct me.
4. Either the REST or SOAP APIs should make your use case very straight forward. Amazon provides a fairly basic "getting started" guide available here. As well, you can view the complete API developer documentation here.

Although the documentation is a little hard to find (likely due to all the name changes), the PA API is very well documented and rather elegant. With a modicum of elbow grease and some previous experience in calling out to web services, you shouldn't have any trouble getting the information you need from the API.

This code calculate difference between two dates in yyyy MM dd format.

declare @StartDate datetime 
declare @EndDate datetime

declare @years int
declare @months int 
declare @days int

--NOTE: date of birth must be smaller than As on date, 
--else it could produce wrong results
set @StartDate = '2013-12-30' --birthdate
set @EndDate  = Getdate()            --current datetime

--calculate years
select @years = datediff(year,@StartDate,@EndDate)

--calculate months if it's value is negative then it 
--indicates after __ months; __ years will be complete
--To resolve this, we have taken a flag @MonthOverflow...
declare @monthOverflow int
select @monthOverflow = case when datediff(month,@StartDate,@EndDate) - 
  ( datediff(year,@StartDate,@EndDate) * 12) <0 then -1 else 1 end
--decrease year by 1 if months are Overflowed
select @Years = case when @monthOverflow < 0 then @years-1 else @years end
select @months =  datediff(month,@StartDate,@EndDate) - (@years * 12) 

--as we do for month overflow criteria for days and hours 
--& minutes logic will followed same way
declare @LastdayOfMonth int
select @LastdayOfMonth =  datepart(d,DATEADD
    (s,-1,DATEADD(mm, DATEDIFF(m,0,@EndDate)+1,0)))

select @days = case when @monthOverflow<0 and 
    DAY(@StartDate)> DAY(@EndDate) 
then @LastdayOfMonth + 
  (datepart(d,@EndDate) - datepart(d,@StartDate) ) - 1  
      else datepart(d,@EndDate) - datepart(d,@StartDate) end 


select
 @Months=case when @days < 0 or DAY(@StartDate)> DAY(@EndDate) then @Months-1 else @Months end

Declare @lastdayAsOnDate int;
set @lastdayAsOnDate = datepart(d,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@EndDate),0)));
Declare @lastdayBirthdate int;
set @lastdayBirthdate =  datepart(d,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@StartDate)+1,0)));

if (@Days < 0) 
(
    select @Days = case when( @lastdayBirthdate > @lastdayAsOnDate) then
        @lastdayBirthdate + @Days
    else
        @lastdayAsOnDate + @Days
    end
)
print  convert(varchar,@years)   + ' year(s),   '  +
       convert(varchar,@months)  + ' month(s),   ' +
       convert(varchar,@days)    + ' day(s)   '   

This is how the ORM maps blank & null fields for Django 1.8

class Test(models.Model):
    charNull        = models.CharField(max_length=10, null=True)
    charBlank       = models.CharField(max_length=10, blank=True)
    charNullBlank   = models.CharField(max_length=10, null=True, blank=True)

    intNull         = models.IntegerField(null=True)
    intBlank        = models.IntegerField(blank=True)
    intNullBlank    = models.IntegerField(null=True, blank=True)

    dateNull        = models.DateTimeField(null=True)
    dateBlank       = models.DateTimeField(blank=True)
    dateNullBlank   = models.DateTimeField(null=True, blank=True)        

The database fields created for PostgreSQL 9.4 are :

CREATE TABLE Test (
  id              serial                    NOT NULL,

  "charNull"      character varying(10),
  "charBlank"     character varying(10)     NOT NULL,
  "charNullBlank" character varying(10),

  "intNull"       integer,
  "intBlank"      integer                   NOT NULL,
  "intNullBlank"  integer,

  "dateNull"      timestamp with time zone,
  "dateBlank"     timestamp with time zone  NOT NULL,
  "dateNullBlank" timestamp with time zone,
  CONSTRAINT Test_pkey PRIMARY KEY (id)
)

The database fields created for MySQL 5.6 are :

CREATE TABLE Test (
     `id`            INT(11)     NOT  NULL    AUTO_INCREMENT,

     `charNull`      VARCHAR(10) NULL DEFAULT NULL,
     `charBlank`     VARCHAR(10) NOT  NULL,
     `charNullBlank` VARCHAR(10) NULL DEFAULT NULL,

     `intNull`       INT(11)     NULL DEFAULT NULL,
     `intBlank`      INT(11)     NOT  NULL,
     `intNullBlank`  INT(11)     NULL DEFAULT NULL,

     `dateNull`      DATETIME    NULL DEFAULT NULL,
     `dateBlank`     DATETIME    NOT  NULL,
     `dateNullBlank` DATETIME    NULL DEFAULT NULL
)

In Java when you are making an object from a class like Person p = new Person();, p is actually an address of a memory location which is pointing to a type of Person.

When use a statemenet to print p you will see an address. The new key word makes a new memory location containing all the instance variables and methods which are included in class Person and p is the reference variable pointing to that memory location.

Probably not exactly your issue..

Do you have any spaces in your package path? You should wrap it up in double quotes to be safe, otherwise it can be taken as two separate arguments

sudo installer -store -pkg "/User/MyName/Desktop/helloWorld.pkg" -target /

For all those working with implicit rules (and GNU MAKE). Here is a simple makefile which supports different directories:

#Start of the makefile

VPATH = ./src:./header:./objects

OUTPUT_OPTION = -o objects/$@

CXXFLAGS += -Wall -g -I./header

Target = $(notdir $(CURDIR)).exe

Objects := $(notdir $(patsubst %.cpp,%.o,$(wildcard src/*.cpp)))



all: $(Target)

$(Target): $(Objects)
     $(CXX) $(CXXFLAGS) -o $(Target) $(addprefix objects/,$(Objects))


#Beware of -f. It skips any confirmation/errors (e.g. file does not exist)

.PHONY: clean
clean:
     rm -f $(addprefix objects/,$(Objects)) $(Target)

Lets have a closer look (I will refer to the current Directory with curdir):

This line is used to get a list of the used .o files which are in curdir/src.

Objects := $(notdir $(patsubst %.cpp,%.o,$(wildcard src/*.cpp)))
#expands to "foo.o myfoo.o otherfoo.o"

Via variable the output is set to a different directory (curdir/objects).

OUTPUT_OPTION = -o objects/$@
#OUTPUT_OPTION will insert the -o flag into the implicit rules

To make sure the compiler finds the objects in the new objects folder, the path is added to the filename.

$(Target): $(Objects)
     $(CXX) $(CXXFLAGS) -o $(Target) $(addprefix objects/,$(Objects))
#                                    ^^^^^^^^^^^^^^^^^^^^    

This is meant as an example and there is definitly room for improvement.

For those attempting Richard's solution above, here are some additional information that might help navigate common errors:

1) When running restore filelistonly you may get Operating system error 5(Access is denied). If that's the case, open SQL Server Configuration Manager and change the login for SQLEXPRESS to a user that has local write privileges.

2) @"This will list the contents of the backup - what you need is the first fields that tell you the logical names" - if your file lists more than two headers you will need to also account for what to do with those files in the RESTORE DATABASE command. If you don't indicate what to do with files beyond the database and the log, the system will apparently try to use the attributes listed in the .bak file. Restoring a file from someone else's environment will produce a 'The path has invalid attributes. It needs to be a directory' (as the path in question doesn't exist on your machine). Simply providing a MOVE statement resolves this problem.

In my case there was a third FTData type file. The MOVE command I added:

MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf',
MOVE 'sysft_...' TO 'c:\temp\other';

in my case I actually had to make a new directory for the third file. Initially I tried to send it to the same folder as the .mdf file but that produced a 'failed to initialize correctly' error on the third FTData file when I executed the restore.

Your JavaScript would have to be defined within a PHP-parsed file.

For example, in index.php you could place

<?php
$time = time();
?>
<script>
    document.write(<?php echo $time; ?>);
</script>

There is no need for using NSAttributedString. All you need is a simple label with the proper textColor. Plus this simple solution will work with all versions of iOS, not just iOS 6.

But if you needlessly wish to use NSAttributedString, you can do something like this:

UIColor *color = [UIColor redColor]; // select needed color
NSString *string = ... // the string to colorize
NSDictionary *attrs = @{ NSForegroundColorAttributeName : color };
NSAttributedString *attrStr = [[NSAttributedString alloc] initWithString:string attributes:attrs];
self.scanLabel.attributedText = attrStr;

Try this:

<SCRIPT LANGUAGE="JavaScript">
 function WriteToFile(passForm) {

    set fso = CreateObject("Scripting.FileSystemObject");  
    set s = fso.CreateTextFile("C:\test.txt", True);
    s.writeline("HI");
    s.writeline("Bye");
    s.writeline("-----------------------------");
    s.Close();
 }
  </SCRIPT>

</head>

<body>
<p>To sign up for the Excel workshop please fill out the form below:
</p>
<form onSubmit="WriteToFile(this)">
Type your first name:
<input type="text" name="FirstName" size="20">
<br>Type your last name:
<input type="text" name="LastName" size="20">
<br>
<input type="submit" value="submit">
</form> 

This will work only on IE

Use element.innerHTML="some \\\\n some";.

If you need your SVGs to be fully styleable with CSS they have to be inline in the DOM. This can be achieved through SVG injection, which uses Javascript to replace a HTML element (usually an <img> element) with the contents of an SVG file after the page has loaded.

Here is a minimal example using SVGInject:

<html>
<head>
  <script src="svg-inject.min.js"></script>
</head>
<body>
  <img src="image.svg" onload="SVGInject(this)" />
</body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the file provided in the src attribute. This works with all browsers that support SVG.
