DataTable, DbDataReader, or IEnumerable<SqlDataRecord> objects can be used to populate a table-valued parameter per the MSDN article Table-Valued Parameters in SQL Server 2008 (ADO.NET).

The following example illustrates using either a DataTable or an IEnumerable<SqlDataRecord>:

SQL Code:

CREATE TABLE dbo.PageView
(
    PageViewID BIGINT NOT NULL CONSTRAINT pkPageView PRIMARY KEY CLUSTERED,
    PageViewCount BIGINT NOT NULL
);
CREATE TYPE dbo.PageViewTableType AS TABLE
(
    PageViewID BIGINT NOT NULL
);
CREATE PROCEDURE dbo.procMergePageView
    @Display dbo.PageViewTableType READONLY
AS
BEGIN
    MERGE INTO dbo.PageView AS T
    USING @Display AS S
    ON T.PageViewID = S.PageViewID
    WHEN MATCHED THEN UPDATE SET T.PageViewCount = T.PageViewCount + 1
    WHEN NOT MATCHED THEN INSERT VALUES(S.PageViewID, 1);
END

C# Code:

private static void ExecuteProcedure(bool useDataTable, 
                                     string connectionString, 
                                     IEnumerable<long> ids) 
{
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    {
        connection.Open();
        using (SqlCommand command = connection.CreateCommand()) 
        {
            command.CommandText = "dbo.procMergePageView";
            command.CommandType = CommandType.StoredProcedure;

            SqlParameter parameter;
            if (useDataTable) {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateDataTable(ids));
            }
            else 
            {
                parameter = command.Parameters
                              .AddWithValue("@Display", CreateSqlDataRecords(ids));
            }
            parameter.SqlDbType = SqlDbType.Structured;
            parameter.TypeName = "dbo.PageViewTableType";

            command.ExecuteNonQuery();
        }
    }
}

private static DataTable CreateDataTable(IEnumerable<long> ids) 
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(long));
    foreach (long id in ids) 
    {
        table.Rows.Add(id);
    }
    return table;
}

private static IEnumerable<SqlDataRecord> CreateSqlDataRecords(IEnumerable<long> ids) 
{
    SqlMetaData[] metaData = new SqlMetaData[1];
    metaData[0] = new SqlMetaData("ID", SqlDbType.BigInt);
    SqlDataRecord record = new SqlDataRecord(metaData);
    foreach (long id in ids) 
    {
        record.SetInt64(0, id);
        yield return record;
    }
}

Multiple Non-query example if anyone is interested.

using (OdbcConnection DbConnection = new OdbcConnection("ConnectionString"))
{
  DbConnection.Open();
  using (OdbcCommand DbCommand = DbConnection.CreateCommand())
  {
    DbCommand.CommandText = "INSERT...";
    DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name";
    DbCommand.ExecuteNonQuery();

    DbCommand.Parameters.Clear();
    DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name2";
    DbCommand.ExecuteNonQuery();
  }
}

you can use implicit casting AddWithValue

cmd.Parameters.AddWithValue("@param1", klantId);
cmd.Parameters.AddWithValue("@param2", klantNaam);
cmd.Parameters.AddWithValue("@param3", klantVoornaam);

sample code,

using (SqlConnection conn = new SqlConnection("connectionString")) 
{
    using (SqlCommand cmd = new SqlCommand()) 
    { 
        cmd.Connection = conn;
        cmd.CommandType = CommandType.Text;
        cmd.CommandText = @"INSERT INTO klant(klant_id,naam,voornaam) 
                            VALUES(@param1,@param2,@param3)";  

        cmd.Parameters.AddWithValue("@param1", klantId);  
        cmd.Parameters.AddWithValue("@param2", klantNaam);  
        cmd.Parameters.AddWithValue("@param3", klantVoornaam);  

        try
        {
            conn.Open();
            cmd.ExecuteNonQuery(); 
        }
        catch(SqlException e)
        {
            MessgeBox.Show(e.Message.ToString(), "Error Message");
        }

    } 
}

Fixed in 8.0.19.

Previously, the system (!) command for the mysql command-line client worked only for Unix and Unix-like systems. It now works on Windows as well. For example, system cls or ! cls may be used to clear the screen.

Try

mysqldump databaseExample > file.sql

sda = new SqlCeDataAdapter("SELECT COUNT(regNumber) AS i FROM  tblAttendance",con);
sda.Fill(dt);

string i = dt.Rows[0]["i"].ToString();
int bar = Convert.ToInt32(i);

if (bar >= 1){

    dt.Clear();
    MetroFramework.MetroMessageBox.Show(this, "something");
}
else if(bar <= 0) {

    dt.Clear();
    MetroFramework.MetroMessageBox.Show(this, "empty");
}

Default timeout is 15 seconds, to change that, 0 is unlimited, any other number is the number of seconds.

In Code

using (SqlCommand sqlCmd = new SqlCommand(sqlQueryString, sqlConnection))
   {
      sqlCmd.CommandTimeout = 0; // 0 = give it as much time as it needs to complete
      ...
    }

In Your Web.Config, "Command Timeout=0;" do not time out, or as below 1 hour (3600 seconds)

  <add name="ConnectionString" connectionString="Data Source=ServerName;User ID=UserName;Password=Password;Command Timeout=3600;" providerName="System.Data.SqlClient" />

EXPOSURE OF API KEYS ISN'T A SECURITY RISK BUT ANYONE CAN PUT YOUR CREDENTIALS ON THEIR SITE.

Open api keys leads to attacks that can use a lot resources at firebase that will definitely cost your hard money.

You can always restrict you firebase project keys to domains / IP's.

https://console.cloud.google.com/apis/credentials/key

select your project Id and key and restrict it to Your Android/iOs/web App.

Java Streams provides elegant way to do that

Stream.of(MyEnum.values()).anyMatch(v -> v.name().equals(strValue))

Returns: true if any elements of the stream match the provided value, otherwise false

I had the same problem, resolved it by adding

<filtering>true</filtering> 

in pom.xml :

before (didn't work):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>               
        </resource>
    </resources>
</build>

after(it worked):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

After that you just run mvn clean install and deploy application.

I was looking for a pretty and simple solution and I found this:

this.setState({ [`image${i}`]: image })

Hope this helps

sqlite3 yourdb .dump > /tmp/db.txt
edit /tmp/db.txt change column name in Create line
sqlite2 yourdb2 < /tmp/db.txt
mv/move yourdb2 yourdb

@Column(name ="LEAD_ID")
private int leadId; 

Change to

@Column(name ="LEAD_ID")
private Integer leadId; 

Maybe this is what you want?

echo foo > test.txt
echo. >> test.txt
echo bar >> test.txt

results in the following within test.txt:

foo

bar

If you use "format-table" you can use -hidetableheaders

protocol must be subClass of AnyObject, class

example given below

    protocol NameOfProtocol: class {
   // member of protocol
    }
   class ClassName: UIViewController {
      weak var delegate: NameOfProtocol? 
    }

Essentially javascript and C++ work on two different principles. Javascript creates an "associative array" or hash table, which matches a string key, which is the field name, to a value. C++ lays out structures in memory, so the first 4 bytes are an integer, which is an age, then maybe we have a fixed-wth 32 byte string which represents the "profession".

So javascript will handle things like "age" being 18 in one record and "nineteen" in another. C++ can't. (However C++ is much faster).

So if we want to handle JSON in C++, we have to build the associative array from the ground up. Then we have to tag the values with their types. Is it an integer, a real value (probably return as "double"), boolean, a string? It follows that a JSON C++ class is quite a large chunk of code. Effectively what we are doing is implementing a bit of the javascript engine in C++. We then pass our JSON parser the JSON as a string, and it tokenises it, and gives us functions to query the JSON from C++.

This is what worked for me. I am not sure why the syntax is different, But it was extremely frustrating trying every combination of activate, inactive, deactivated, disabled, etc. In lower case upper case in quotes out of quotes in brackets out of brackets etc. Well, here's the winning combination for me, for some reason.. different than everyone else?

import tkinter

class App(object):
    def __init__(self):
        self.tree = None
        self._setup_widgets()

    def _setup_widgets(self):
        butts = tkinter.Button(text = "add line", state="disabled")
        butts.grid()

def main():  
    root = tkinter.Tk()
    app = App()
    root.mainloop()

if __name__ == "__main__":
    main()

Here's a small example to demonstrate this (which only applied to DataFrames, not Series, until Pandas 0.19 where it applies to both):

In [1]: df1 = pd.DataFrame([[1, 2], [3, 4]])

In [2]: df2 = pd.DataFrame([[3, 4], [1, 2]], index=[1, 0])

In [3]: df1 == df2
Exception: Can only compare identically-labeled DataFrame objects

One solution is to sort the index first (Note: some functions require sorted indexes):

In [4]: df2.sort_index(inplace=True)

In [5]: df1 == df2
Out[5]: 
      0     1
0  True  True
1  True  True

Note: == is also sensitive to the order of columns, so you may have to use sort_index(axis=1):

In [11]: df1.sort_index().sort_index(axis=1) == df2.sort_index().sort_index(axis=1)
Out[11]: 
      0     1
0  True  True
1  True  True

Note: This can still raise (if the index/columns aren't identically labelled after sorting).

Absolutely valid.

    <form action="javascript:alert('Hello there, I am being submitted');">
        <button type="submit">
            Let's do it
        </button>
    </form>
    <!-- Tested in Firefox, Chrome, Edge and Safari -->

So for a short answer: yes, this is an option, and a nice one. It says "when submitted, please don't go anywhere, just run this script" - quite to the point.

A minor improvement

To let the event handler know which form we're dealing with, it would seem an obvious way to pass on the sender object:

    <form action="javascript:myFunction(this)">  <!-- should work, but it won't -->

But instead, it will give you undefined. You can't access it because javascript: links live in a separate scope. Therefore I'd suggest the following format, it's only 13 characters more and works like a charm:

    <form action="javascript:;" onsubmit="myFunction(this)">  <!-- now you have it! -->

... now you can access the sender form properly. (You can write a simple "#" as action, it's quite common - but it has a side effect of scrolling to the top when submitting.)

Again, I like this approach because it's effortless and self-explaining. No "return false", no jQuery/domReady, no heavy weapons. It just does what it seems to do. Surely other methods work too, but for me, this is The Way Of The Samurai.

A note on validation

Forms only get submitted if their onsubmit event handler returns something truthy, so you can easily run some preemptive checks:

    <form action="/something.php" onsubmit="return isMyFormValid(this)">

Now isMyFormValid will run first, and if it returns false, server won't even be bothered. Needless to say, you will have to validate on server side too, and that's the more important one. But for quick and convenient early detection this is fine.

Yes, there is a way. Its called custom fonts in CSS.Your CSS needs to be modified, and you need to upload those fonts to your website.

The CSS required for this is:

@font-face {
     font-family: Thonburi-Bold;
     src: url('pathway/Thonburi-Bold.otf'); 
}

Now that Javascript has lookbehind (as of ES2018), on newer environments, you can avoid groups entirely in situations like these. Rather, lookbehind for what comes before the group you were capturing, and lookahead for what comes after, and replace with just !NEW_ID!:

const str = 'name="some_text_0_some_text"';
console.log(
  str.replace(/(?<=name="\w+)\d+(?=\w+")/, '!NEW_ID!')
);

With this method, the full match is only the part that needs to be replaced.

• (?<=name="\w+) - Lookbehind for name=", followed by word characters (luckily, lookbehinds do not have to be fixed width in Javascript!)
• \d+ - Match one or more digits - the only part of the pattern not in a lookaround, the only part of the string that will be in the resulting match
• (?=\w+") - Lookahead for word characters followed by " `

Keep in mind that lookbehind is pretty new. It works in modern versions of V8 (including Chrome, Opera, and Node), but not in most other environments, at least not yet. So while you can reliably use lookbehind in Node and in your own browser (if it runs on a modern version of V8), it's not yet sufficiently supported by random clients (like on a public website).

Scrum is a very specific set of practices. Agile describes a family of practices, everything from Extreme Programming to Scrum and almost anything else that uses short iterations can claim Agile. That may not have originally been the case when the term was coined, but it certainly is by now.

if you don't want to use parser :

int a;
String s;
Scanner scan = new Scanner(System.in);

System.out.println("enter a no");
a = scan.nextInt();
System.out.println("no is =" + a);
scan.nextLine(); // This line you have to add (It consumes the \n character)
System.out.println("enter a string");
s = scan.nextLine();
System.out.println("string is=" + s);

Here are 3 separate approaches to the problem in hand along with the best choices of indexing for each of those queries (please try out the indexes yourselves and see the logical read, elapsed time, execution plan. I have provided the suggestions from my experience on such queries without executing for this specific problem).

Approach 1: Using ROW_NUMBER(). If rowstore index is not being able to enhance the performance, you can try out nonclustered/clustered columnstore index as for queries with aggregation and grouping and for tables which are ordered by in different columns all the times, columnstore index usually is the best choice.

;WITH CTE AS
    (
       SELECT   *,
                RN = ROW_NUMBER() OVER (PARTITION BY DocumentID ORDER BY DateCreated DESC)
       FROM     DocumentStatusLogs
    )
    SELECT  ID      
        ,DocumentID 
        ,Status     
        ,DateCreated
    FROM    CTE
    WHERE   RN = 1;

Approach 2: Using FIRST_VALUE. If rowstore index is not being able to enhance the performance, you can try out nonclustered/clustered columnstore index as for queries with aggregation and grouping and for tables which are ordered by in different columns all the times, columnstore index usually is the best choice.

SELECT  DISTINCT
    ID      = FIRST_VALUE(ID) OVER (PARTITION BY DocumentID ORDER BY DateCreated DESC)
    ,DocumentID
    ,Status     = FIRST_VALUE(Status) OVER (PARTITION BY DocumentID ORDER BY DateCreated DESC)
    ,DateCreated    = FIRST_VALUE(DateCreated) OVER (PARTITION BY DocumentID ORDER BY DateCreated DESC)
FROM    DocumentStatusLogs;

Approach 3: Using CROSS APPLY. Creating rowstore index on DocumentStatusLogs table covering the columns used in the query should be enough to cover the query without need of a columnstore index.

SELECT  DISTINCT
    ID      = CA.ID
    ,DocumentID = D.DocumentID
    ,Status     = CA.Status 
    ,DateCreated    = CA.DateCreated
FROM    DocumentStatusLogs D
    CROSS APPLY (
            SELECT  TOP 1 I.*
            FROM    DocumentStatusLogs I
            WHERE   I.DocumentID = D.DocumentID
            ORDER   BY I.DateCreated DESC
            ) CA;

If your destination element is empty and will only contain the <svg> tag you could consider using ng-bind-html as follow :

Declare your HTML tag in the directive scope variable

link: function (scope, iElement, iAttrs) {

    scope.svgTag = '<svg width="600" height="100" class="svg"></svg>';

    ...
}

Then, in your directive template, just add the proper attribute at the exact place you want to append the svg tag :

<!-- start of directive template code -->
...
<!-- end of directive template code -->
<div ng-bind-html="svgTag"></div>

Don't forget to include ngSanitize to allow ng-bind-html to automatically parse the HTML string to trusted HTML and avoid insecure code injection warnings.

See official documentation for more details.

The problem with systemPath is that the dependencies' jars won't get distributed along your artifacts as transitive dependencies. Try what I've posted here: Is it best to Mavenize your project jar files or put them in WEB-INF/lib?

Then declare dependencies as usual.

And please read the footer note.

Another example:

Dim myPath As String = """" & Path.Combine(part1, part2) & """"

Good luck!

You need to create the matplotlib Figure and Axes objects ahead of time, specifying how big the figure is:

from matplotlib import pyplot
import seaborn

import mylib

a4_dims = (11.7, 8.27)
df = mylib.load_data()
fig, ax = pyplot.subplots(figsize=a4_dims)
seaborn.violinplot(ax=ax, data=df, **violin_options)

Pure bash, done in two separate operations:

1. Remove the path from a path-string:

   path=/foo/bar/bim/baz/file.gif
   
   file=${path##*/}  
   #$file is now 'file.gif'
   

2. Remove the extension from a path-string:

   base=${file%.*}
   #${base} is now 'file'.
   

While this isn't possible with the video itself, you could use a canvas to draw the frames of the video except for pixels in a color range or whatever. It would take some javascript and such of course. See Video Puzzle (apparently broken at the moment), Exploding Video, and Realtime Video -> ASCII

@Frode F. gave the right answer.

By the Way Invoke-WebRequest also prints you the 200 OK and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod which is lighter.

Also, keep in mind that you need to use | ConvertTo-Json for the body only, not the header:

$body = @{
 "UserSessionId"="12345678"
 "OptionalEmail"="[email protected]"
} | ConvertTo-Json

$header = @{
 "Accept"="application/json"
 "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
 "Content-Type"="application/json"
} 

Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML

and you can then append a | ConvertTo-HTML at the end of the request for better readability

It can be treated as defensive programming approach from the compiler - the variables must be assigned before it can be used.

I had this problem and the instructions from a tech at Microsoft fixed it for me:

• Close all instances of Visual Studio.
• Open the Task Manager and check if any TFS Services are running. Select each of them and click on End Process Tree.
• Browse to the folder below and delete all the contents and folders in %LocalAppData%\Microsoft\Team Foundation{version}\Cache
• Go to Control Panel -> User Accounts -> Manage your Credential -> Windows Credential, select the VSTS URL to remove it
• Then go to "C:\Users\USER NAME\AppData\Local\GitCredentialManager\tenant.cache" and delete it
• Also go to "C:\Users\USER NAME\AppData\Local.IdentityService" and delete it

C99 defines "%zd" etc. for that. (thanks to the commenters) There is no portable format specifier for that in C++ - you could use %p, which woulkd word in these two scenarios, but isn't a portable choice either, and gives the value in hex.

Alternatively, use some streaming (e.g. stringstream) or a safe printf replacement such as Boost Format. I understand that this advice is only of limited use (and does require C++). (We've used a similar approach fitted for our needs when implementing unicode support.)

The fundamental problem for C is that printf using an ellipsis is unsafe by design - it needs to determine the additional argument's size from the known arguments, so it can't be fixed to support "whatever you got". So unless your compiler implement some proprietary extensions, you are out of luck.

There are some good answers already. I'll focus mainly on what I think they lack - an explanation of the "cons" with the copy-and-swap idiom....

What is the copy-and-swap idiom?

A way of implementing the assignment operator in terms of a swap function:

X& operator=(X rhs)
{
    swap(rhs);
    return *this;
}

The fundamental idea is that:

• the most error-prone part of assigning to an object is ensuring any resources the new state needs are acquired (e.g. memory, descriptors)

• that acquisition can be attempted before modifying the current state of the object (i.e. *this) if a copy of the new value is made, which is why rhs is accepted by value (i.e. copied) rather than by reference

• swapping the state of the local copy rhs and *this is usually relatively easy to do without potential failure/exceptions, given the local copy doesn't need any particular state afterwards (just needs state fit for the destructor to run, much as for an object being moved from in >= C++11)

When should it be used? (Which problems does it solve [/create]?)

• When you want the assigned-to objected unaffected by an assignment that throws an exception, assuming you have or can write a swap with strong exception guarantee, and ideally one that can't fail/throw..†

• When you want a clean, easy to understand, robust way to define the assignment operator in terms of (simpler) copy constructor, swap and destructor functions.

  • Self-assignment done as a copy-and-swap avoids oft-overlooked edge cases.‡

• When any performance penalty or momentarily higher resource usage created by having an extra temporary object during the assignment is not important to your application. ?

† swap throwing: it's generally possible to reliably swap data members that the objects track by pointer, but non-pointer data members that don't have a throw-free swap, or for which swapping has to be implemented as X tmp = lhs; lhs = rhs; rhs = tmp; and copy-construction or assignment may throw, still have the potential to fail leaving some data members swapped and others not. This potential applies even to C++03 std::string's as James comments on another answer:

@wilhelmtell: In C++03, there is no mention of exceptions potentially thrown by std::string::swap (which is called by std::swap). In C++0x, std::string::swap is noexcept and must not throw exceptions. – James McNellis Dec 22 '10 at 15:24

‡ assignment operator implementation that seems sane when assigning from a distinct object can easily fail for self-assignment. While it might seem unimaginable that client code would even attempt self-assignment, it can happen relatively easily during algo operations on containers, with x = f(x); code where f is (perhaps only for some #ifdef branches) a macro ala #define f(x) x or a function returning a reference to x, or even (likely inefficient but concise) code like x = c1 ? x * 2 : c2 ? x / 2 : x;). For example:

struct X
{
    T* p_;
    size_t size_;
    X& operator=(const X& rhs)
    {
        delete[] p_;  // OUCH!
        p_ = new T[size_ = rhs.size_];
        std::copy(p_, rhs.p_, rhs.p_ + rhs.size_);
    }
    ...
};

On self-assignment, the above code delete's x.p_;, points p_ at a newly allocated heap region, then attempts to read the uninitialised data therein (Undefined Behaviour), if that doesn't do anything too weird, copy attempts a self-assignment to every just-destructed 'T'!

? The copy-and-swap idiom can introduce inefficiencies or limitations due to the use of an extra temporary (when the operator's parameter is copy-constructed):

struct Client
{
    IP_Address ip_address_;
    int socket_;
    X(const X& rhs)
      : ip_address_(rhs.ip_address_), socket_(connect(rhs.ip_address_))
    { }
};

Here, a hand-written Client::operator= might check if *this is already connected to the same server as rhs (perhaps sending a "reset" code if useful), whereas the copy-and-swap approach would invoke the copy-constructor which would likely be written to open a distinct socket connection then close the original one. Not only could that mean a remote network interaction instead of a simple in-process variable copy, it could run afoul of client or server limits on socket resources or connections. (Of course this class has a pretty horrid interface, but that's another matter ;-P).

If you have a relatively- (or otherwise-) positioned div you can center something inside it with margin:auto

Vertical centering is a bit tricker, but possible.

I know I am late, but if you want to know the easiest way, you could do a code like this:

number = 100
right_questions = 1
control = 100
c = control / number
cc = right_questions * c
print float(cc)

You can change up the number score, and right_questions. It will tell you the percent.

@kajetons' answer is fully functional.

You can also pass multiple variables by passing them like: use($var1, $var2)

DB::table('users')->where(function ($query) use ($activated,$var2) {
    $query->where('activated', '=', $activated);
    $query->where('var2', '>', $var2);
})->get();

I have also encountered this error . Just i opened the new window ie Window -> New Window in eclipse .Then , I closed my old window. This solved my problem.

With Android Studio, try this:

//region VARIABLES
private String _sMyVar1;
private String _sMyVar2;
//endregion

Careful : no blank line after //region ...

And you will get:

1. Create SDK folder at \Android\Sdk
2. Close any project which is already open in Android studio

Android Studio setup wizard will appear and perform the needed installation.

Code written in Java is:

• First compiled to bytecode by a program called javac as shown in the left section of the image above;
• Then, as shown in the right section of the above image, another program called java starts the Java runtime environment and it may compile and/or interpret the bytecode by using the Java Interpreter/JIT Compiler.

When does java interpret the bytecode and when does it compile it? The application code is initially interpreted, but the JVM monitors which sequences of bytecode are frequently executed and translates them to machine code for direct execution on the hardware. For bytecode which is executed only a few times, this saves the compilation time and reduces the initial latency; for frequently executed bytecode, JIT compilation is used to run at high speed, after an initial phase of slow interpretation. Additionally, since a program spends most time executing a minority of its code, the reduced compilation time is significant. Finally, during the initial code interpretation, execution statistics can be collected before compilation, which helps to perform better optimization.

Import jquery first before bootstrap:

If you have a date object:

let date = new Date()_x000D_
let result = date.toISOString().split`T`[0]_x000D_
_x000D_
console.log(result)

or

let date = new Date()_x000D_
let result = date.toISOString().slice(0, 10)_x000D_
_x000D_
console.log(result)

Method for converting from one timeZone to other(probably it works :) ).

/**
 * Adapt calendar to client time zone.
 * @param calendar - adapting calendar
 * @param timeZone - client time zone
 * @return adapt calendar to client time zone
 */
public static Calendar convertCalendar(final Calendar calendar, final TimeZone timeZone) {
    Calendar ret = new GregorianCalendar(timeZone);
    ret.setTimeInMillis(calendar.getTimeInMillis() +
            timeZone.getOffset(calendar.getTimeInMillis()) -
            TimeZone.getDefault().getOffset(calendar.getTimeInMillis()));
    ret.getTime();
    return ret;
}

To convert serialize object to String and String to Object

stringToBean(beanToString(new LoginMdp()), LoginMdp.class);

public static String beanToString(Object object) throws IOException {

    ObjectMapper objectMapper = new ObjectMapper();
    StringWriter stringEmp = new StringWriter();
    objectMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
    objectMapper.writeValue(stringEmp, object);
    return stringEmp.toString();
}

public static <T> T stringToBean(String content, Class<T> valueType) throws IOException {
    return new ObjectMapper().readValue(content, valueType);
}

I think the best way is to test for functionality rather than versions. In some cases, this is trivial, not so in others.

eg:

try :
    # Do stuff
except : # Features weren't found.
    # Do stuff for older versions.

As long as you're specific in enough in using the try/except blocks, you can cover most of your bases.

I got this error after creating an event source under the Application Log from the command line using "EventCreate". This command creates a new key under: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application

If you look at the Key that's been created (e.g. SourceTest) there will be a string value calledEventMessageFile, which for me was set to %SystemRoot%\System32\EventCreate.exe.

Change this to c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll

Delete theCustomSource and TypesSupported values.

This should stop the "The description for Event ID...." message.

I would wrap the text in a so you can target it separately. Now if you float both and left, you can use line-height to control the vertical spacing of the . Setting it to the same height as the (30px) will middle align it. See here.

New Markup:

 <div>
    <i class='icon icon-2x icon-camera'></i>
    <span id="text">hello world</span>
</div>

New CSS:

div {
    border: 1px solid #ccc;
    height: 30px;
    margin: 60px;
    padding: 4px;
    vertical-align: middle;
}
i{
    float: left;
}
#text{
    line-height: 30px;
    float: left;
}

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

You can use the following script to convert jupyter notebook to Python script, or view the code directly.

To do this, write the following contents into a file cat_ipynb, then chmod +x cat_ipynb.

#!/usr/bin/env python
import sys
import json

for file in sys.argv[1:]:
    print('# file: %s' % file)
    print('# vi: filetype=python')
    print('')
    code = json.load(open(file))

    for cell in code['cells']:
        if cell['cell_type'] == 'code':
            print('# -------- code --------')
            for line in cell['source']:
                print(line, end='')
            print('\n')
        elif cell['cell_type'] == 'markdown':
            print('# -------- markdown --------')
            for line in cell['source']:
                print("#", line, end='')
            print('\n')

Then you can use

cat_ipynb your_notebook.ipynb > output.py

Or show it with vi directly

cat_ipynb your_notebook.ipynb | view -

try this:

bigInt.sign = number < 0 ? 0 : 1

Here is an approach that to me seems quite straightforward, and easier that adding an AttachedBehaviour (which is also a valid solution). We use the default UpdateSourceTrigger (LostFocus for TextBox), and then add an InputBinding to the Enter Key, bound to a command.

The xaml is as follows

       <TextBox Grid.Row="0" Text="{Binding Txt1}" Height="30" Width="150">
        <TextBox.InputBindings>
            <KeyBinding Gesture="Enter" 
                        Command="{Binding UpdateText1Command}"
                        CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}},Path=Text}" />
        </TextBox.InputBindings>
    </TextBox>

Then the Command methods are

Private Function CanExecuteUpdateText1(ByVal param As Object) As Boolean
    Return True
End Function
Private Sub ExecuteUpdateText1(ByVal param As Object)

    If TypeOf param Is String Then
        Txt1 = CType(param, String)
    End If
End Sub

And the TextBox is bound to the Property

 Public Property Txt1 As String
    Get
        Return _txt1
    End Get
    Set(value As String)
        _txt1 = value
        OnPropertyChanged("Txt1")
    End Set
End Property

So far this seems to work well and catches the Enter Key event in the TextBox.

What you are looking for is disabled="true". Here is an example:

<textarea class="customPayload" disabled="true" *ngIf="!showSpinner"></textarea>

Another way to understand those concept is as follow: Depth: Draw a horizontal line at the root position and treat this line as ground. So the depth of the root is 0, and all its children are grow downward so each level of nodes has the current depth + 1.

Height: Same horizontal line but this time the ground position is external nodes, which is the leaf of tree and count upward.

I implemented this in java and ran a unit test (source below). None of the above solutions work. This code passes the unit test. If anyone finds a unit test that does not pass, please let me know.

Code: NOTE: nearlyEqual(double,double) returns true if the two numbers are very close.

/*
 * @return integer code for which side of the line ab c is on.  1 means
 * left turn, -1 means right turn.  Returns
 * 0 if all three are on a line
 */
public static int findSide(
        double ax, double ay, 
        double bx, double by,
        double cx, double cy) {
    if (nearlyEqual(bx-ax,0)) { // vertical line
        if (cx < bx) {
            return by > ay ? 1 : -1;
        }
        if (cx > bx) {
            return by > ay ? -1 : 1;
        } 
        return 0;
    }
    if (nearlyEqual(by-ay,0)) { // horizontal line
        if (cy < by) {
            return bx > ax ? -1 : 1;
        }
        if (cy > by) {
            return bx > ax ? 1 : -1;
        } 
        return 0;
    }
    double slope = (by - ay) / (bx - ax);
    double yIntercept = ay - ax * slope;
    double cSolution = (slope*cx) + yIntercept;
    if (slope != 0) {
        if (cy > cSolution) {
            return bx > ax ? 1 : -1;
        }
        if (cy < cSolution) {
            return bx > ax ? -1 : 1;
        }
        return 0;
    }
    return 0;
}

Here's the unit test:

    assertTrue("1", 1 == Utility.findSide(1, 0, 0, 0, -1, -1));

sort() was deprecated for DataFrames in favor of either:

• sort_values() to sort by column(s)
• sort_index() to sort by the index

sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).

I had the same issue when I tried to use git.

It is possible to install git without it. And I doubt that gcc on mac is truly dependent on XCode. And I don't want to use root to accept something unless I'm sure I need it.

I uninstalled XCode by navigating to the applications folder and dragging XCode to the trash.

Now my git commands work as usual. I'll re-install XCode if/when I truly need it.

If you are able to allow the ASPNET and associated users permission to read & write a file, you can easily use an HTML file with standard String.Format() placeholders ({0}, {1:C}, etc.) to accomplish this.

Merely read in the file, as a string, using classes from the System.IO namespace. Once you have that string, pass it as the first argument to String.Format(), and provide the parameters.

Keep that string around, and use it as the body of the e-mail, and you're essentially done. We do this on dozens of (admittedly small) sites today, and have had no issues.

I should note that this works best if (a) you're not sending zillions of e-mails at a time, (b) you're not personalizing each e-mail (otherwise you eat up a ton of strings) and (c) the HTML file itself is relatively small.

I tried what kohske wrote as an answer and I got error again, so I did some search and found this which worked for me (R 3.0.2):

require(splines) # package
detach(package:splines)

or also

library(splines)
pkg <- "package:splines"
detach(pkg, character.only = TRUE)

I would probably use regexp matches if the input has only a few valid entries. E.g. only the "start" and "stop" are valid actions.

if [[ "${ACTION,,}" =~ ^(start|stop)$ ]]; then
  echo "valid action"
fi

Note that I lowercase the variable $ACTION by using the double comma's. Also note that this won't work on too aged bash versions out there.

Import the jquery CDN as a first

(e.g)

<script
  src="https://code.jquery.com/jquery-3.3.1.min.js"
  integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
  crossorigin="anonymous"></script>

I think what you want is Browser-Based Uploads Using POST.

Basically, you do need server-side code, but all it does is generate signed policies. Once the client-side code has the signed policy, it can upload using POST directly to S3 without the data going through your server.

Here's the official doc links:

Diagram: http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingHTTPPOST.html

Example code: http://docs.aws.amazon.com/AmazonS3/latest/dev/HTTPPOSTExamples.html

The signed policy would go in your html in a form like this:

<html>
  <head>
    ...
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    ...
  </head>
  <body>
  ...
  <form action="http://johnsmith.s3.amazonaws.com/" method="post" enctype="multipart/form-data">
    Key to upload: <input type="input" name="key" value="user/eric/" /><br />
    <input type="hidden" name="acl" value="public-read" />
    <input type="hidden" name="success_action_redirect" value="http://johnsmith.s3.amazonaws.com/successful_upload.html" />
    Content-Type: <input type="input" name="Content-Type" value="image/jpeg" /><br />
    <input type="hidden" name="x-amz-meta-uuid" value="14365123651274" />
    Tags for File: <input type="input" name="x-amz-meta-tag" value="" /><br />
    <input type="hidden" name="AWSAccessKeyId" value="AKIAIOSFODNN7EXAMPLE" />
    <input type="hidden" name="Policy" value="POLICY" />
    <input type="hidden" name="Signature" value="SIGNATURE" />
    File: <input type="file" name="file" /> <br />
    <!-- The elements after this will be ignored -->
    <input type="submit" name="submit" value="Upload to Amazon S3" />
  </form>
  ...
</html>

Notice the FORM action is sending the file directly to S3 - not via your server.

Every time one of your users wants to upload a file, you would create the POLICY and SIGNATURE on your server. You return the page to the user's browser. The user can then upload a file directly to S3 without going through your server.

When you sign the policy, you typically make the policy expire after a few minutes. This forces your users to talk to your server before uploading. This lets you monitor and limit uploads if you desire.

The only data going to or from your server is the signed URLs. Your secret keys stay secret on the server.

Here's an implementation using node-http-proxy from nodejitsu.

var http = require('http');
var httpProxy = require('http-proxy');
var proxy = httpProxy.createProxyServer({});

http.createServer(function(req, res) {
    proxy.web(req, res, { target: 'http://www.google.com' });
}).listen(3000);

As JoshC said, the class .sr-only is used to visually hide the information used for screen readers only. But not only to hide labels. You might consider hiding various other elements such as "skip to main content" link, icons which have an alternative texts etc.

BTW. you can also use .sr-only sr-only-focusable if you need the element to become visible when focused e.g. "skip to main content"

If you want make your website even more accessible I recommend to start here:

• Accessibility @Google - Web Fundamentals
• Accessibility Developer Guide (my personal favorite)
• WebAIM Principles + WebAIM WCAG Checklist
• Accessibility @ReactJS (lots of good resources and general stuff)

Why?

According to the World Health Organization, 285 million people have vision impairments. So making a website accessible is important.

IMPORTANT: Avoid treating disabled users differently. Generally speaking try to avoid developing a different content for different groups of users. Instead try to make accessible the existing content so that it simply works out-of-the-box and for all not specifically targeting e.g. screen readers. In other words don't try to reinvent the wheel. Otherwise the resulting accessibility will often be worse than if there was nothing developed at all. We developers should not assume how those users will use our website. So be very careful when you need to develop such solutions. Obviously a "skip link" is a good example of such content if it's made visible when focused. But there many bad examples too. Such would be hiding from a screen reader a "zoom" button on the map assuming that it has no relevance to blind users. But surprisingly, a zoom function indeed is used among blind users! They like to download images like many other users do (even in high resolution), for sending them to somebody else or for using them in some other context.

You can do it using a straight forward select like this:

SELECT * 
FROM sys.indexes 
WHERE name='YourIndexName' AND object_id = OBJECT_ID('Schema.YourTableName')

This is kind of a hack but the best solution that I have found is to use a description tag with no \item. This will produce an error from the latex compiler; however, the error does not prevent the pdf from being generated.

\begin{description} 
     <YOUR TEXT HERE> 
\end{description}

• This only worked on windows latex compiler

string ToBeReplaceCharacters = @"~()@#$%&+,'"<>|;\/*?";
string fileName = "filename;with<bad:separators?";

foreach (var RepChar in ToBeReplaceCharacters)
{
    fileName = fileName.Replace(RepChar.ToString(), "");
}

UPDATE: Check out AngularUI's new project to address this problem

For subsections it's as easy as leveraging strings in ng-include:

<ul id="subNav">
  <li><a ng-click="subPage='section1/subpage1.htm'">Sub Page 1</a></li>
  <li><a ng-click="subPage='section1/subpage2.htm'">Sub Page 2</a></li>
  <li><a ng-click="subPage='section1/subpage3.htm'">Sub Page 3</a></li>
</ul>
<ng-include src="subPage"></ng-include>

Or you can create an object in case you have links to sub pages all over the place:

$scope.pages = { page1: 'section1/subpage1.htm', ... };

<ul id="subNav">
  <li><a ng-click="subPage='page1'">Sub Page 1</a></li>
  <li><a ng-click="subPage='page2'">Sub Page 2</a></li>
  <li><a ng-click="subPage='page3'">Sub Page 3</a></li>
</ul>
<ng-include src="pages[subPage]"></ng-include>

Or you can even use $routeParams

$routeProvider.when('/home', ...);
$routeProvider.when('/home/:tab', ...);
$scope.params = $routeParams;

<ul id="subNav">
  <li><a href="#/home/tab1">Sub Page 1</a></li>
  <li><a href="#/home/tab2">Sub Page 2</a></li>
  <li><a href="#/home/tab3">Sub Page 3</a></li>
</ul>
<ng-include src=" '/home/' + tab + '.html' "></ng-include>

You can also put an ng-controller at the top-most level of each partial

Always generate script and review before you run. Below the script

  select 'Alter table dbo.' + t.name + ' drop constraint '+ d.name  
  from sys.tables t
  join sys.default_constraints d on d.parent_object_id = t.object_id
  join sys.columns c on c.object_id = t.object_id
       and c.column_id = d.parent_column_id
  where c.name in ('VersionEffectiveDate','VersionEndDate','VersionReasonDesc')
  order by t.name

it's not true the clear() function clear the Arraylist and start from index 0

Neither. You should separate content and presentation, giving your HTML code logical codes. Think of it this way; to a blind person, or on a browser that cannot display colors, what is left of your code? Why do you want it to be red?

Most probably, your decision to make text red is because you want to give it emphasis. So your HTML code should be:

<em>test</em>

This way, even non-visual browsers can make sure they give the text emphasis in one way or another.

Next step is to make the text red. But you don't want to add the color code everywhere, much more efficient to just add it once:

<style>

This way, all emphasized code on your website becomes red, making it more constant.

On Chrome's latest update (38.0.2125.104 m at the moment), Google added the option to know whether the files loaded to the website were newly downloaded from the server - or read from the local cache.

When an error like yours "hits" the console - you know the files were just downloaded from the server and not read from the local cache. You can recreate this error by clicking Ctrl + F5 (refresh and erase cache).

It fits your description where Firebug (or equivalents) doesn't fire any errors to the console - whilst Chrome does.

So, the bottom line is - your're just fine and you can ignore this error - it's merely an indicator.

    byte[] seed = (SALT2 + username + password).getBytes();
    SecureRandom random = new SecureRandom(seed);
    KeyGenerator generator;
    generator = KeyGenerator.getInstance("AES");
    generator.init(random);
    generator.init(256);
    Key keyObj = generator.generateKey();

As for me, these are just different methods. The first one leaves the object you're iterating on unchanged, while the seconds leaves it empty. The question is what do you want to do. The complexity of removing is based on implementation of your iterable object. If you're using Collections - just obtain the size like was proposed by Kazekage Gaara - its usually the best approach performance wise.

You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:

render: function() {
  return (
    <span>
      // This will go through all the elements in arrayFromJson and
      // render each one as a <SomeComponent /> with data from the object
      {this.state.arrayFromJson.map(function(object) {
        return (
          <SomeComponent key={object.id} data={object} />
        );
      })}
    </span>
  );
}

Hope Below steps will help

Add the dependency to your project-level build.gradle:

classpath 'com.google.gms:google-services:3.0.0'

Add the plugin to your app-level build.gradle:

apply plugin: 'com.google.gms.google-services'

app-level build.gradle:

dependencies {
        compile 'com.google.android.gms:play-services-auth:9.8.0'
}

To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:

public class Child : Parent 
{
    public void LoadData() 
    {
        base.MyMethod(); // call method of parent class
        base.CurrentRow = 1; // set property of parent class
        // other stuff...
    }
}

Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

Actually its pretty easy to make integration between Csharp (VS) and Python with IronPython. It's not that much complex... As Chris Dunaway already said in answer section I started to build this inegration for my own project. N its pretty simple. Just follow these steps N you will get your results.

step 1 : Open VS and create new empty ConsoleApp project.

step 2 : Go to tools --> NuGet Package Manager --> Package Manager Console.

step 3 : After this open this link in your browser and copy the NuGet Command. Link: https://www.nuget.org/packages/IronPython/2.7.9

step 4 : After opening the above link copy the PM>Install-Package IronPython -Version 2.7.9 command and paste it in NuGet Console in VS. It will install the supportive packages.

step 5 : This is my code that I have used to run a .py file stored in my Python.exe directory.

using IronPython.Hosting;//for DLHE
using Microsoft.Scripting.Hosting;//provides scripting abilities comparable to batch files
using System;
using System.Diagnostics;
using System.IO;
using System.Net;
using System.Net.Sockets;
class Hi
{
private static void Main(string []args)
{
Process process = new Process(); //to make a process call
ScriptEngine engine = Python.CreateEngine(); //For Engine to initiate the script
engine.ExecuteFile(@"C:\Users\daulmalik\AppData\Local\Programs\Python\Python37\p1.py");//Path of my .py file that I would like to see running in console after running my .cs file from VS.//process.StandardInput.Flush();
process.StandardInput.Close();//to close
process.WaitForExit();//to hold the process i.e. cmd screen as output
}
} 

step 6 : save and execute the code

;WITH tmp(SomeID, OtherID, DataItem, Data) as (
    SELECT SomeID, OtherID, LEFT(Data, CHARINDEX(',',Data+',')-1),
        STUFF(Data, 1, CHARINDEX(',',Data+','), '')
FROM Testdata
WHERE Data > ''
)
SELECT SomeID, OtherID, Data
FROM tmp
ORDER BY SomeID

with only tiny little modification to above query...

sed can perform text transformations on input stream from a file or from a pipeline. Example:

echo 'C:\foo\bar.xml' | sed 's/\\/\//g'

gets

C:/foo/bar.xml

.circle {
    border-radius: 50%;
    width: 500px;
    height: 500px;
    background: red;
}

<div class="circle"></div>

see this FIDDLE

The simplest method is

$dateArray = explode('/', $_POST['date']);
$date = $dateArray[2].'-'.$dateArray[0].'-'.$dateArray[1];

$sql = mysql_query("INSERT INTO user_date (column,column,column) VALUES('',$name,$date)") or die (mysql_error());

Because it is not portable.

is a windows / dos only program, so this your code won't run on linux. Moreover, system is not generally regarded as a very good way to call another program - it is usually better to use CreateProcess or fork or something similar.

It can be done using % operator. i.e. SELECT 50 % 5

As far as I know there is no built in svn command to accomplish this. You would need to write a script to run several commands to build all the diffs. A simpler approach would be to use a GUI svn client if that is an option. Many of them such as the subversive plugin for Eclipse will list the history of a file as well as allow you to view the diff of each revision.

You can edit this behavior in:

Tools->Options->Text Editor->All Languages->Tabs

Change Tab to use "Insert Spaces" instead of "Keep Tabs".

Note you can also specify this per language if you wish to have different behavior in a specific language.

Did a quick google. Seems that to find the file size you do this,

long size = f.length();

The differences between the three methods you posted can be found here

getFreeSpace() and getTotalSpace() are pretty self explanatory, getUsableSpace() seems to be the space that the JVM can use, which in most cases will be the same as the amount of free space.

There are two issues here:

The first issue is, adding to an Collection after an Iterator is returned. As mentioned, there is no defined behavior when the underlying Collection is modified, as noted in the documentation for Iterator.remove:

... The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

The second issue is, even if an Iterator could be obtained, and then return to the same element the Iterator was at, there is no guarantee about the order of the iteratation, as noted in the Collection.iterator method documentation:

... There are no guarantees concerning the order in which the elements are returned (unless this collection is an instance of some class that provides a guarantee).

For example, let's say we have the list [1, 2, 3, 4].

Let's say 5 was added when the Iterator was at 3, and somehow, we get an Iterator that can resume the iteration from 4. However, there is no guarentee that 5 will come after 4. The iteration order may be [5, 1, 2, 3, 4] -- then the iterator will still miss the element 5.

As there is no guarantee to the behavior, one cannot assume that things will happen in a certain way.

One alternative could be to have a separate Collection to which the newly created elements can be added to, and then iterating over those elements:

Collection<String> list = Arrays.asList(new String[]{"Hello", "World!"});
Collection<String> additionalList = new ArrayList<String>();

for (String s : list) {
    // Found a need to add a new element to iterate over,
    // so add it to another list that will be iterated later:
    additionalList.add(s);
}

for (String s : additionalList) {
    // Iterate over the elements that needs to be iterated over:
    System.out.println(s);
}

Edit

Elaborating on Avi's answer, it is possible to queue up the elements that we want to iterate over into a queue, and remove the elements while the queue has elements. This will allow the "iteration" over the new elements in addition to the original elements.

Let's look at how it would work.

Conceptually, if we have the following elements in the queue:

[1, 2, 3, 4]

And, when we remove 1, we decide to add 42, the queue will be as the following:

[2, 3, 4, 42]

As the queue is a FIFO (first-in, first-out) data structure, this ordering is typical. (As noted in the documentation for the Queue interface, this is not a necessity of a Queue. Take the case of PriorityQueue which orders the elements by their natural ordering, so that's not FIFO.)

The following is an example using a LinkedList (which is a Queue) in order to go through all the elements along with additional elements added during the dequeing. Similar to the example above, the element 42 is added when the element 2 is removed:

Queue<Integer> queue = new LinkedList<Integer>();
queue.add(1);
queue.add(2);
queue.add(3);
queue.add(4);

while (!queue.isEmpty()) {
    Integer i = queue.remove();
    if (i == 2)
        queue.add(42);

    System.out.println(i);
}

The result is the following:

1
2
3
4
42

As hoped, the element 42 which was added when we hit 2 appeared.

I have provide two methods for doing so for minutes as well as for years and hours if you want to see more examples:

import datetime
print(datetime.datetime.now())
print(datetime.datetime.now() - datetime.timedelta(minutes = 15))
print(datetime.datetime.now() + datetime.timedelta(minutes = -15))
print(datetime.timedelta(hours = 5))
print(datetime.datetime.now() + datetime.timedelta(days = 3))
print(datetime.datetime.now() + datetime.timedelta(days = -9))
print(datetime.datetime.now() - datetime.timedelta(days = 9))

I get the following results:

2016-06-03 16:04:03.706615
2016-06-03 15:49:03.706622
2016-06-03 15:49:03.706642
5:00:00

Just add ! before an exclusion rule.

According to the gitignore man page:

Patterns have the following format:

...

• An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

in my case, it just because the mysql server runs together with an application , who write too many logs that the disk is full.

you can check if the disk has enough space use

df -h

if the disk usage percentage is 100%, you can use this command to find which directory is too large

du -h -d 1 /

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

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

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

I found this:

http://www.robvanderwoude.com/commandlineswitches.php#Acrobat

Open a PDF file with navigation pane active, zoom out to 50%, and search for and highlight the word "batch":

AcroRd32.exe /A "zoom=50&navpanes=1=OpenActions&search=batch" PdfFile

Double period (..) means you go up one folder and then look for the folder behind the slash. For example:

If your index.html is in the folder html/files and the fonts are in html/fonts, the .. is fine (because you have to go back one folder to go to /fonts). Is your index.html in html and your fonts in html/fonts, then you should use only one period.

Another problem could be that your browser might not support .eot font-files.

Without seeing more of your code (and maybe a link to a live version of your website), I can't really help you further.

Edit: Forget the .eot part, I missed the .ttf file in your css.

Try the following:

@font-face { 
font-family: Gotham;
src: url(../fonts/gothammedium.eot);
src: url(../fonts/Gotham-Medium.ttf); 
}

How about playing with these two properties?

It is useful when you share a variable between a few modules. You define it in one module, and use extern in the others.

For example:

in file1.cpp:

int global_int = 1;

in file2.cpp:

extern int global_int;
//in some function
cout << "global_int = " << global_int;

From one of my other posts, getting a unixtimestamp:

$unixTimestamp = time();

Converting to mysql datetime format:

$mysqlTimestamp = date("Y-m-d H:i:s", $unixTimestamp);

Getting some mysql timestamp:

$mysqlTimestamp = '2013-01-10 12:13:37';

Converting it to a unixtimestamp:

$unixTimestamp = strtotime('2010-05-17 19:13:37');

...comparing it with one or a range of times, to see if the user entered a realistic time:

if($unixTimestamp > strtotime("1999-12-15") && $unixTimestamp < strtotime("2025-12-15"))
{...}

Unix timestamps are safer too. You can do the following to check if a url passed variable is valid, before checking (for example) the previous range check:

if(ctype_digit($_GET["UpdateTimestamp"]))
{...}

$str = "http://www.vimeo.com/1234567";
$s = explode("/",$str);
print end($s);

$@ is the name of the target being generated, and $< the first prerequisite (usually a source file). You can find a list of all these special variables in the GNU Make manual.

For example, consider the following declaration:

all: library.cpp main.cpp

In this case:

• $@ evaluates to all
• $< evaluates to library.cpp
• $^ evaluates to library.cpp main.cpp

I had an issue with the Visual Studio Update 3 installer getting stuck on the "Features" tab at ther very start of installation...it would show only "Update 2 (installed)" and nothing else, with no way to proceed.

After trying some of the other more complex advice here, it turned out, to my surprise, that all I needed to do was use "Run as Administrator" when kicking off the installer. I was under the impression MSI generally runs with Admin privileges (under the Trusted Installer service) but I suppose the VS bootstrapper in this case does not.

// Add this middleware
// error handler
app.use(function(err, req, res, next) {
 // set locals, only providing error in development
   res.locals.message = err.message;
   res.locals.error = req.app.get('env') === 'development' ? err : {};

 // render the error page
   res.status(err.status || 500);
   res.render('error');
  });

Google Guava provides another way to do this with Strings#repeat():

String repeated = Strings.repeat("pete and re", 42);

I created 2 servers, listening on same port 8081, running from same code, while learning

1st server creation shud have worked 2nd server creation failed with EADDRINUSE

node.js callback delays might be reason behind neither worked, or 2nd server creation had exception, and program exited, so 1st server is also closed

2 server issue hint, I got from: How to fix Error: listen EADDRINUSE while using nodejs?

As stated in many of the above answers, the === operator is used under the hood on case/when statements.

Here is additional information about that operator:

Case equality operator: ===

Many of Ruby's built-in classes, such as String, Range, and Regexp, provide their own implementations of the === operator, also known as "case-equality", "triple equals" or "threequals". Because it's implemented differently in each class, it will behave differently depending on the type of object it was called on. Generally, it returns true if the object on the right "belongs to" or "is a member of" the object on the left. For instance, it can be used to test if an object is an instance of a class (or one of its sub-classes).

String === "zen"  # Output: => true
Range === (1..2)   # Output: => true
Array === [1,2,3]   # Output: => true
Integer === 2   # Output: => true

The same result can be achieved with other methods which are probably best suited for the job, such as is_a? and instance_of?.

Range Implementation of ===

When the === operator is called on a range object, it returns true if the value on the right falls within the range on the left.

(1..4) === 3  # Output: => true
(1..4) === 2.345 # Output: => true
(1..4) === 6  # Output: => false

("a".."d") === "c" # Output: => true
("a".."d") === "e" # Output: => false

Remember that the === operator invokes the === method of the left-hand object. So (1..4) === 3 is equivalent to (1..4).=== 3. In other words, the class of the left-hand operand will define which implementation of the === method will be called, so the operand positions are not interchangeable.

Regexp Implementation of ===

Returns true if the string on the right matches the regular expression on the left.

/zen/ === "practice zazen today"  # Output: => true
# is similar to
"practice zazen today"=~ /zen/

The only relevant difference between the two examples above is that, when there is a match, === returns true and =~ returns an integer, which is a truthy value in Ruby. We will get back to this soon.

Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.

Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

• fix #xxx
• fixes #xxx
• fixed #xxx
• close #xxx
• closes #xxx
• closed #xxx
• resolve #xxx
• resolves #xxx
• resolved #xxx

You can also substitute #xxx with gh-xxx.

Referencing and closing issues across repos also works:

fixes user/repo#xxx

If your cascading deletes nuke a product because it was a member of a category that was killed, then you've set up your foreign keys improperly. Given your example tables, you should have the following table setup:

CREATE TABLE categories (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE products (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE categories_products (
    category_id int unsigned not null,
    product_id int unsigned not null,
    PRIMARY KEY (category_id, product_id),
    KEY pkey (product_id),
    FOREIGN KEY (category_id) REFERENCES categories (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE,
    FOREIGN KEY (product_id) REFERENCES products (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE
)Engine=InnoDB;

This way, you can delete a product OR a category, and only the associated records in categories_products will die alongside. The cascade won't travel farther up the tree and delete the parent product/category table.

e.g.

products: boots, mittens, hats, coats
categories: red, green, blue, white, black

prod/cats: red boots, green mittens, red coats, black hats

If you delete the 'red' category, then only the 'red' entry in the categories table dies, as well as the two entries prod/cats: 'red boots' and 'red coats'.

The delete will not cascade any farther and will not take out the 'boots' and 'coats' categories.

comment followup:

you're still misunderstanding how cascaded deletes work. They only affect the tables in which the "on delete cascade" is defined. In this case, the cascade is set in the "categories_products" table. If you delete the 'red' category, the only records that will cascade delete in categories_products are those where category_id = red. It won't touch any records where 'category_id = blue', and it would not travel onwards to the "products" table, because there's no foreign key defined in that table.

Here's a more concrete example:

categories:     products:
+----+------+   +----+---------+
| id | name |   | id | name    |
+----+------+   +----+---------+
| 1  | red  |   | 1  | mittens |
| 2  | blue |   | 2  | boots   |
+---++------+   +----+---------+

products_categories:
+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 1          | 2           | // blue mittens
| 2          | 1           | // red boots
| 2          | 2           | // blue boots
+------------+-------------+

Let's say you delete category #2 (blue):

DELETE FROM categories WHERE (id = 2);

the DBMS will look at all the tables which have a foreign key pointing at the 'categories' table, and delete the records where the matching id is 2. Since we only defined the foreign key relationship in products_categories, you end up with this table once the delete completes:

+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 2          | 1           | // red boots
+------------+-------------+

There's no foreign key defined in the products table, so the cascade will not work there, so you've still got boots and mittens listed. There's just no 'blue boots' and no 'blue mittens' anymore.

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

Here's another re + itertools version that should work when searching for either a str or a RegexpObject. I will freely admit that this is likely over-engineered, but for some reason it entertained me.

import itertools
import re

def find_nth(haystack, needle, n = 1):
    """
    Find the starting index of the nth occurrence of ``needle`` in \
    ``haystack``.

    If ``needle`` is a ``str``, this will perform an exact substring
    match; if it is a ``RegexpObject``, this will perform a regex
    search.

    If ``needle`` doesn't appear in ``haystack``, return ``-1``. If
    ``needle`` doesn't appear in ``haystack`` ``n`` times,
    return ``-1``.

    Arguments
    ---------
    * ``needle`` the substring (or a ``RegexpObject``) to find
    * ``haystack`` is a ``str``
    * an ``int`` indicating which occurrence to find; defaults to ``1``

    >>> find_nth("foo", "o", 1)
    1
    >>> find_nth("foo", "o", 2)
    2
    >>> find_nth("foo", "o", 3)
    -1
    >>> find_nth("foo", "b")
    -1
    >>> import re
    >>> either_o = re.compile("[oO]")
    >>> find_nth("foo", either_o, 1)
    1
    >>> find_nth("FOO", either_o, 1)
    1
    """
    if (hasattr(needle, 'finditer')):
        matches = needle.finditer(haystack)
    else:
        matches = re.finditer(re.escape(needle), haystack)
    start_here = itertools.dropwhile(lambda x: x[0] < n, enumerate(matches, 1))
    try:

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

No need to touch hot_standby_feedback. As others have mentioned, setting it to on can bloat master. Imagine opening transaction on a slave and not closing it.

Instead, set max_standby_archive_delay and max_standby_streaming_delay to some sane value:

# /etc/postgresql/10/main/postgresql.conf on a slave
max_standby_archive_delay = 900s
max_standby_streaming_delay = 900s

This way queries on slaves with a duration less than 900 seconds won't be cancelled. If your workload requires longer queries, just set these options to a higher value.

Modal Window using ExtJS approach.

Your .eslintrc.json should contain the text below.
This way ESLint knows about your global variables.

{
  "env": {
    "browser": true,
    "node": true
  }

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

If you want to change R's language in terminal to English forever, this works fine for me in macOS:

Open terminal.app, and say:

touch .bash_profile

Then say:

open -a TextEdit.app .bash_profile

These two commands will help you open ".bash_profile" file in TextEdit.

Add this to ".bash_profile" file:

export LANG=en_US.UTF-8

Then save the file, reopen terminal and type R, you will find it's language has changed to english.

If you want language come back to it's original, just simply add a # before export LANG=en_US.UTF-8.

nodeEnter.append("svg:image")

I have got this error report problem, too. My code is under below.

public static void getShop() throws Exception {
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                OkHttpClient client = new OkHttpClient();
                Request request = new Request.Builder()
                        .url("https://10.0.2.2:8010/getShopInfo/aaa")
                        .build();
                Response response = client.newCall(request).execute();
                Log.d("response", response.body().string());
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }).start();
}

I have my Springboot as my backend and use Android OKHttp to get information. The critical mistake i made was that i use a .url("https://10.0.2.2:8010/getShopInfo/aaa") in code of Android. But the my backend is not allowed https request. After i use .url("http://10.0.2.2:8010/getShopInfo/aaa"), then my code went well. So, i want to say my mistake is not the version of emulator, it about the request protocol. I meet another problem after doing what i said, but it's another problem, and i attach the resolve method of the new problem .
Good Luck!GUY!

FLCL's idea is very correct, I show you in a code:

    public class O1<T> where T: class
    {
        public Guid Id { get; }
        public O1(Guid id)
        {
            Id = id;
        }
        public bool IsNull => !GlobalHolder.Holder.ContainsKey(Id);
        public T Val => GlobalHolder.Holder.ContainsKey(Id) ? (T)GlobalHolder.Holder[Id] : null;
    }
    public class GlobalHolder
    {
        public static readonly Dictionary<Guid, object> Holder = new Dictionary<Guid, object>();
        public static O1<T> Instantiate<T>() where T: class, new()
        {
            var a = new T();
            var nguid = Guid.NewGuid();
            var b = new O1<T>(nguid);
            Holder[nguid] = a;
            return b;
        }
        public static void Destroy<T>(O1<T> obj) where T: class
        {
            Holder.Remove(obj.Id);
        }
    }

    public class Animal
    {

    }

    public class AnimalTest
    {
        public static void Test()
        {
            var tom = GlobalHolder.Instantiate<Animal>();
            var duplicateTomReference = tom;
            GlobalHolder.Destroy(tom);
            Console.WriteLine($"{duplicateTomReference.IsNull}");
            // prints true
        }
    }

Note: In this code sample, my naming convention comes from Unity.

By setting and unsetting the setCustomValidity in the right time, the validation message will work flawlessly.

<input name="Username" required 
oninvalid="this.setCustomValidity('Username cannot be empty.')" 
onchange="this.setCustomValidity('')" type="text" />

I used onchange instead of oninput which is more general and occurs when the value is changed in any condition even through JavaScript.

As per the author, they want to create a script in the head, not a link to a script file. Also, to avoid complications from jQuery (which provides little useful functionality in this case), vanilla javascript is likely the better option.

That may possibly be done as such:

var script = document.createTextNode("<script>alert('Hi!');</script>");   
document.getElementsByTagName('head')[0].appendChild(script);

Do you want to detect when the window has been resized?

You can use JQuery's resize to attach a handler.

I have had this issue and that doesn't mean, that the same library is loaded many times but System is trying to load a class with the same name and possibly same package name simultaneously, i.e.

• com.pack1.de and Class Geometry of library1.jar

and another

• com.pack1.de and Class Geometry of library2.jar.

How should you approach? You should analyze which methods are being used, a method of library1.jar or library2.

There are 2 Solutions,

1. Rename a packagename and then dalvik interprets, that they are distinct classes
2. Or if you want to risk, purge the class, which doesn't contain the methode, which we really use.

I hope that has clarified this often asked question.

Jarret Hardie is correct. Or, first merge your changes back into master and then try the push. By default, git push pushes all branches that have names that match on the remote -- and no others. So those are your two choices -- either specify it explicitly like Jarret said or merge back to a common branch and then push.

There's been talk about this on the Git mail list and it's clear that this behavior is not about to change anytime soon -- many developers rely on this behavior in their workflows.

Edit/Clarification

Assuming your upstreammaster branch is ready to push then you could do this:

1. Pull in any changes from the upstream.

   $ git pull upstream master

2. Switch to my local master branch

   $ git checkout master

3. Merge changes in from upstreammaster

   $ git merge upstreammaster

4. Push my changes up

   $ git push upstream

Another thing that you may want to do before pushing is to rebase your changes against upstream/master so that your commits are all together. You can either do that as a separate step between #1 and #2 above (git rebase upstream/master) or you can do it as part of your pull (git pull --rebase upstream master)

Call After would be a better name than the stupid name, callback. When or if condition gets met within a function, call another function, the Call After function, the one received as argument.

Rather than hard-code an inner function within a function, one writes a function to accept an already-written Call After function as argument. The Call After might get called based on state changes detected by code in the function receiving the argument.

If you are doing this because you want more context in your search, you can do this:

cat BIG_FILE.txt | less

Doing a search in less should highlight your search terms.

Or pipe the output to your favorite editor. One example:

cat BIG_FILE.txt | vim -

Then search/highlight/replace.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

Following are the references that may explain Architecture in more detail and a list of UML diagrams for software architecture. (I could not find listing of UML diagrams for software design )

Grady Booch

Classification of UML diagrams

Even after posting this answer, i myself is not clear which diagram is for architecture and which one for design :). Grady Booch, in his slide # 58, states that Classes, Interfaces and Collaborations are part of Design View and this Design View is one of the View of Architecture !!!

I also had problem understanding next() , but this helped

var app = require("express")();

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write("Hello");
    next(); //remove this and see what happens 
});

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write(" World !!!");
    httpResponse.end();
});

app.listen(8080);

You can also run conda init as below,

C:\ProgramData\Anaconda3\Scripts\conda init cmd.exe

or

C:\ProgramData\Anaconda3\Scripts\conda init powershell

Note that the execution policy of powershell must be set, e.g. using Set-ExecutionPolicy Unrestricted.

You can use it as: data = recvall(sock)

def recvall(sock):
    BUFF_SIZE = 4096 # 4 KiB
    data = b''
    while True:
        part = sock.recv(BUFF_SIZE)
        data += part
        if len(part) < BUFF_SIZE:
            # either 0 or end of data
            break
    return data

Thou shalt always encode URLs.

Here is how Ruby encodes your URL:

irb(main):008:0> CGI.escape "a.com/a+b"
=> "a.com%2Fa%2Bb"

If you would like to mount a particular host directory (/disk1/prometheus-data in the following example) as a volume in the volumes section of the Docker Compose YAML file, you can do it as below, e.g.:

version: '3'

services:
  prometheus:
    image: prom/prometheus
    volumes:
      - prometheus-data:/prometheus

volumes:
  prometheus-data:
    driver: local
    driver_opts:
      o: bind
      type: none
      device: /disk1/prometheus-data

By the way, in prometheus's Dockerfile, You may find the VOLUME instruction as below, which marks it as holding externally mounted volumes from native host, etc. (Note however: this instruction is not a must though to mount a volume into a container.):

Dockerfile

...
VOLUME ["/prometheus"]

    // arrSelected [1]['item0','item1','item2'] 

    // You need to get the iteration value. 
    //
    selected.each((idx, val) => {
        arrSelected.push(val.value);
    });
    // arrSelected [0]['item0'] 
    // arrSelected [1]['item1']
    // arrSelected [2]['item2']
});

These both work fine for me...

<?php
  $db = mysql_connect('localhost','user','pass');
  mysql_select_db('test_db');

  $stmt = "INSERT INTO `test` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}','{$last}','NOW())";
  $rslt = mysql_query($stmt);

  $stmt = "INSERT INTO `users` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}', '{$last}', CURRENT_TIMESTAMP)";
  $rslt = mysql_query($stmt);

?>

Side note: mysql_query() is not the best way to connect to MySQL in current versions of PHP.

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

Thanks for the suggestions in the comments. I made a bit of a dirty hack to get what I want without having to create my own image. With javascript I first hide the default tag that's being used for the down arrow, like so:

$('b[role="presentation"]').hide();

I then included font-awesome in my page and add my own down arrow, again with a line of javascript, to replace the default one:

$('.select2-arrow').append('<i class="fa fa-angle-down"></i>');

Then with CSS I style the select boxes. I set the height, change the background color of the arrow area to a gradient black, change the width, font-size and also the color of the down arrow to white:

.select2-container .select2-choice {
    padding: 5px 10px;
    height: 40px;
    width: 132px; 
    font-size: 1.2em;  
}

.select2-container .select2-choice .select2-arrow {
    background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
    background-image: -moz-linear-gradient(top, #424242, #030303);
    background-image: -ms-linear-gradient(top, #424242, #030303);
    background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
    background-image: -webkit-linear-gradient(top, #424242, #030303);
    background-image: -o-linear-gradient(top, #424242, #030303);
    background-image: linear-gradient(#424242, #030303);
    width: 40px;
    color: #fff;
    font-size: 1.3em;
    padding: 4px 12px;
}

The result is the styling the way I want it:

Update 5/6/2015 As @Katie Lacy mentioned in the other answer the classnames have been changed in version 4 of Select2. The updated CSS with the new classnames should look like this:

.select2-container--default .select2-selection--single{
    padding:6px;
    height: 37px;
    width: 148px; 
    font-size: 1.2em;  
    position: relative;
}

.select2-container--default .select2-selection--single .select2-selection__arrow {
    background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
    background-image: -moz-linear-gradient(top, #424242, #030303);
    background-image: -ms-linear-gradient(top, #424242, #030303);
    background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
    background-image: -webkit-linear-gradient(top, #424242, #030303);
    background-image: -o-linear-gradient(top, #424242, #030303);
    background-image: linear-gradient(#424242, #030303);
    width: 40px;
    color: #fff;
    font-size: 1.3em;
    padding: 4px 12px;
    height: 27px;
    position: absolute;
    top: 0px;
    right: 0px;
    width: 20px;
}

JS:

$('b[role="presentation"]').hide();
$('.select2-selection__arrow').append('<i class="fa fa-angle-down"></i>');

There is an article in MSDN which describes the differences:

Comparing Web Site Projects and Web Application Projects

BTW: there are some similar questions about that topic, e.g:

• Web Site vs. ASP.Net Web Application in Visual Studio note: was removed, no longer on SO
• website or webapplication in.ASP.NET

Swift 4 answer:

// Define paragraph style - you got to pass it along to NSAttributedString constructor
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center

// Define attributed string attributes
let attributes = [NSAttributedStringKey.paragraphStyle: paragraphStyle]

let attributedString = NSAttributedString(string:"Test", attributes: attributes)

Set it with a px value. Changing the code like below should work

el.css('marginLeft', mrg + 'px');

The SQLiteDatabase.deleteDatabase(File file) static method was added in API 16. If you want to write apps that support older devices, how do you do this?

I tried: file.delete();

but it messes up SQLiteOpenHelper.

Thanks.

NEVER MIND! I later realized you are using Context.deleteDatabase(). The Context one works great and deletes the journal too. Works for me.

Also, I found I needed to call SQLiteOpenHelp.close() before doing the delete, so that I could then use LoaderManager to recreate it.

You can also use the NSString class methods which will also create an autoreleased instance and have more options like string formatting:

NSString *myString = [NSString stringWithString:@"abc"];
NSString *myString = [NSString stringWithFormat:@"abc %d efg", 42];

Untested....but should work.

Dim lastrow as long

lastrow = range("D65000").end(xlup).Row

ActiveCell.FormulaR1C1 = _
        "=IF(MONTH(RC[-1])>3,"" ""&YEAR(RC[-1])&""-""&RIGHT(YEAR(RC[-1])+1,2),"" ""&YEAR(RC[-1])-1&""-""&RIGHT(YEAR(RC[-1]),2))"
    Selection.AutoFill Destination:=Range("E2:E" & lastrow)
    'Selection.AutoFill Destination:=Range("E2:E"& lastrow)
    Range("E2:E1344").Select

Only exception being are you sure your Autofill code is perfect...

json-loader doesn't load json file if it's array, in this case you need to make sure it has a key, for example

{
    "items": [
    {
      "url": "https://api.github.com/repos/vmg/redcarpet/issues/598",
      "repository_url": "https://api.github.com/repos/vmg/redcarpet",
      "labels_url": "https://api.github.com/repos/vmg/redcarpet/issues/598/labels{/name}",
      "comments_url": "https://api.github.com/repos/vmg/redcarpet/issues/598/comments",
      "events_url": "https://api.github.com/repos/vmg/redcarpet/issues/598/events",
      "html_url": "https://github.com/vmg/redcarpet/issues/598",
      "id": 199425790,
      "number": 598,
      "title": "Just a heads up (LINE SEPARATOR character issue)",
    },
    ..... other items in array .....
]}

You could encode your values, for example in PHP base64_encode($str) / base64_decode($str)

IMO this is simpler than doubling up quotes, etc.

https://www.php.net/manual/en/function.base64-encode.php

The encoded values will never contain a comma so every comma in your CSV will be a separator.

This worked for me:

$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(false);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(10);

be sure to add setAuzoSize(false), before the setWidth(); as Rolland mentioned

The Answer already posted .But We can use the jquery in this way also

demo

$(function(){
    $('#check1').click(function() {
        if($('#check1').attr('checked'))
            alert('checked');
        else
            alert('unchecked');
    });

    $('#check2').click(function() {
        if(!$('#check2').attr('checked'))
            alert('unchecked');
        else
            alert('checked');
    });
});

select propety

Row Source Type => Value List

Code :

ListbName.ColumnCount=2

ListbName.AddItem "value column1;value column2"

Any easy way to cover ALL file inputs is to just style your input[type=button] and drop this in globally to turn file inputs into buttons:

$(document).ready(function() {
    $("input[type=file]").each(function () {
        var thisInput$ = $(this);
        var newElement = $("<input type='button' value='Choose File' />");
        newElement.click(function() {
            thisInput$.click();
        });
        thisInput$.after(newElement);
        thisInput$.hide();
    });
});

Here's some sample button CSS that I got from http://cssdeck.com/labs/beautiful-flat-buttons:

input[type=button] {
  position: relative;
  vertical-align: top;
  width: 100%;
  height: 60px;
  padding: 0;
  font-size: 22px;
  color:white;
  text-align: center;
  text-shadow: 0 1px 2px rgba(0, 0, 0, 0.25);
  background: #454545;
  border: 0;
  border-bottom: 2px solid #2f2e2e;
  cursor: pointer;
  -webkit-box-shadow: inset 0 -2px #2f2e2e;
  box-shadow: inset 0 -2px #2f2e2e;
}
input[type=button]:active {
  top: 1px;
  outline: none;
  -webkit-box-shadow: none;
  box-shadow: none;
}

Or you may do the following

$(this).animate({color:'black'},1000);

But you need to download the color plugin from here.

    SELECT `locations`.`name`
      FROM `locations`
INNER JOIN `school_locations`
        ON `locations`.`id` = `school_locations`.`location_id`
INNER JOIN `schools`
        ON `school_locations`.`school_id` = `schools_id`
     WHERE `type` = 'coun';

the WHERE clause has to be at the end of the statement

I dont think there is a need to replace any quotes, this is a perfectly formed JSON string, you just need to convert JSON string into object.This article perfectly explains the situation : Link

Example :

success: function (data) {

        // assuming that everything is correct and there is no exception being thrown
        // output string {"d":"{"username":"hi","email":"[email protected]","password":"123"}"}
        // now we need to remove the double quotes (as it will create problem and 
        // if double quotes aren't removed then this JSON string is useless)
        // The output string : {"d":"{"username":"hi","email":"[email protected]","password":"123"}"}
        // The required string : {"d":{username:"hi",email:"[email protected]",password:"123"}"}
        // For security reasons the d is added (indicating the return "data")
        // so actually we need to convert data.d into series of objects
        // Inbuilt function "JSON.Parse" will return streams of objects
        // JSON String : "{"username":"hi","email":"[email protected]","password":"123"}"
        console.log(data);                     // output  : Object {d="{"username":"hi","email":"[email protected]","password":"123"}"}
        console.log(data.d);                   // output : {"username":"hi","email":"[email protected]","password":"123"} (accessing what's stored in "d")
        console.log(data.d[0]);                // output : {  (just accessing the first element of array of "strings")
        var content = JSON.parse(data.d);      // output : Object {username:"hi",email:"[email protected]",password:"123"}" (correct)
        console.log(content.username);         // output : hi 
        var _name = content.username;
        alert(_name);                         // hi

}

You can use the Java UUID class to store these values, instead of byte arrays:

UUID

public UUID(long mostSigBits,
            long leastSigBits)

Constructs a new UUID using the specified data. mostSigBits is used for the most significant 64 bits of the UUID and leastSigBits becomes the least significant 64 bits of the UUID.

You don't need those imports. The only thing you need in your urls.py (to start) is:

from django.conf.urls.defaults import *

# This two if you want to enable the Django Admin: (recommended)
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    # ... your url patterns
)

NOTE: This solution was intended for Django <1.6. This was actually the code generated by Django itself. For newer version, see Jacob Hume's answer.

You can also simply use this:

.bg_rgba {
  background: linear-gradient(0deg, rgba(255, 255, 255, 0.9), rgba(255, 255, 255, 0.9)), url('https://picsum.photos/200');
  width: 200px;
  height: 200px;
  border: 1px solid black;
}

<div class='bg_rgba'></div>

You can change the opacity of the color to your preference.

This forum on MSDN tells you.

Form.Close() sends the proper Windows messages to shut down the win32 window. During that process, if the form was not shown modally, Dispose is called on the form. Disposing the form frees up the unmanaged resources that the form is holding onto.

If you do a form1.Show() or Application.Run(new Form1()), Dispose will be called when Close() is called.

However, if you do form1.ShowDialog() to show the form modally, the form will not be disposed, and you'll need to call form1.Dispose() yourself. I believe this is the only time you should worry about disposing the form yourself.

It depends. If it's a dynamically allocated array, that is, you created it calling malloc, then as others suggest you must either save the size of the array/number of elements somewhere or have a sentinel (a struct with a special value, that will be the last one).

If it's a static array, you can sizeof it's size/the size of one element. For example:

int array[10], array_size;
...
array_size = sizeof(array)/sizeof(int);

Note that, unless it's global, this only works in the scope where you initialized the array, because if you past it to another function it gets decayed to a pointer.

Hope it helps.

Json isn't a huge language to start with, so libraries for it are likely to be small(er than Xml libraries, at least).

There are a whole ton of C libraries linked at Json.org. Maybe one of them will work well for you.

You can check the element existence by

arr.Any(x => x == "One")

You can use

start "" "%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"

or

start "" /D "%USERPROFILE%\Desktop\BGInfo" bginfo.exe dc_bginfo.bgi

or

"%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"

or

cd /D "%USERPROFILE%\Desktop\BGInfo"
bginfo.exe dc_bginfo.bgi

Help on commands start and cd is output by executing in a command prompt window help start or start /? and help cd or cd /?.

But I do not understand why you need a batch file at all for starting the application with the additional parameter. Create a shortcut (*.lnk) on your desktop for this application. Then right click on the shortcut, left click on Properties and append after a space character "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi" as parameter.

More robust:

function trim(word)
{
    word = word.replace(/[^\x21-\x7E]+/g, ' '); // change non-printing chars to spaces
    return word.replace(/^\s+|\s+$/g, '');      // remove leading/trailing spaces
}

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

I think you're getting confused about what can hold what in JSON.Net.

• A JToken is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.
• A JProperty is a single JToken value paired with a name. It can only be added to a JObject, and its value cannot be another JProperty.
• A JObject is a collection of JProperties. It cannot hold any other kind of JToken directly.

In your code, you are attempting to add a JObject (the one containing the "banana" data) to a JProperty ("orange") which already has a value (a JObject containing {"colour":"orange","size":"large"}). As you saw, this will result in an error.

What you really want to do is add a JProperty called "banana" to the JObject which contains the other fruit JProperties. Here is the revised code:

JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));

This is a link to a great Case Study on the industry wide misunderstanding of controlling caches.

http://securityevaluators.com/knowledge/case_studies/caching/

In summary, according to this article, only Cache-Control: no-store is recognized by Chrome, Firefox, and IE. IE recognizes other controls, but Chrome and Firefox do not.

I used interop to open Excel and to modify the column widths once the data was done. If you use interop to spit the data into a new Excel workbook (if this is what you want), it will be terribly slow. Instead, I generated a .CSV, then opened the .CSV in Excel. This has its own problems, but I've found this the quickest method.

First, convert the .CSV:

// Convert array data into CSV format.
// Modified from http://csharphelper.com/blog/2018/04/write-a-csv-file-from-an-array-in-c/.
private string GetCSV(List<string> Headers, List<List<double>> Data)
{
    // Get the bounds.
    var rows = Data[0].Count;
    var cols = Data.Count;
    var row = 0;

    // Convert the array into a CSV string.
    StringBuilder sb = new StringBuilder();

    // Add the first field in this row.
    sb.Append(Headers[0]);

    // Add the other fields in this row separated by commas.
    for (int col = 1; col < cols; col++)
        sb.Append("," + Headers[col]);

    // Move to the next line.
    sb.AppendLine();

    for (row = 0; row < rows; row++)
    {
        // Add the first field in this row.
        sb.Append(Data[0][row]);

        // Add the other fields in this row separated by commas.
        for (int col = 1; col < cols; col++)
            sb.Append("," + Data[col][row]);

        // Move to the next line.
        sb.AppendLine();
    }

    // Return the CSV format string.
    return sb.ToString();
}

Then, export it to Excel:

public void ExportToExcel()
{
    // Initialize app and pop Excel on the screen.
    var excelApp = new Excel.Application { Visible = true };

    // I use unix time to give the files a unique name that's almost somewhat useful.
    DateTime dateTime = DateTime.UtcNow;
    long unixTime = ((DateTimeOffset)dateTime).ToUnixTimeSeconds();
    var path = @"C:\Users\my\path\here + unixTime + ".csv";

    var csv = GetCSV();
    File.WriteAllText(path, csv);

    // Create a new workbook and get its active sheet.
    excelApp.Workbooks.Open(path);

    var workSheet = (Excel.Worksheet)excelApp.ActiveSheet;

    // iterate over each value and throw it in the chart
    for (var column = 0; column < Data.Count; column++)
    {
        ((Excel.Range)workSheet.Columns[column + 1]).AutoFit();
    }

    currentSheet = workSheet;
}

You'll have to install some stuff, too...

1. Right click on the solution from solution explorer and select "Manage NuGet Packages." - add Microsoft.Office.Interop.Excel

2. It might actually work right now if you created the project the way interop wants you to. If it still doesn't work, I had to create a new project in a different category. Under New > Project, select Visual C# > Windows Desktop > Console App. Otherwise, the interop tools won't work.

In case I forgot anything, here's my 'using' statements:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;

Request.Url will return you the Uri of the request. Once you have that, you can retrieve pretty much anything you want. To get the protocol, call the Scheme property.

Sample:

Uri url = Request.Url;
string protocol = url.Scheme;

Hope this helps.

So notice variables are on the stack, the values they refer to are on the heap. So having variables is not too bad but yes they do create references to other entities. However in the simple case you describe it's not really any consequence. If it is never read again and within a contained scope, the compiler will probably strip it out before runtime. Even if it didn't the garbage collector will be able to safely remove it after the stack squashes. If you are running into issues where you have too many stack variables, it's usually because you have really deep stacks. The amount of stack space needed per thread is a better place to adjust than to make your code unreadable. The setting to null is also no longer needed

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

In WPF there are certain 'container' controls that automatically resize their contents and there are some that don't.

Here are some that do not resize their contents (I'm guessing that you are using one or more of these):

StackPanel
WrapPanel
Canvas
TabControl

Here are some that do resize their contents:

Grid
UniformGrid
DockPanel

Therefore, it is almost always preferable to use a Grid instead of a StackPanel unless you do not want automatic resizing to occur. Please note that it is still possible for a Grid to not size its inner controls... it all depends on your Grid.RowDefinition and Grid.ColumnDefinition settings:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="100" /> <!--<<< Exact Height... won't resize -->
        <RowDefinition Height="Auto" /> <!--<<< Will resize to the size of contents -->
        <RowDefinition Height="*" /> <!--<<< Will resize taking all remaining space -->
    </Grid.RowDefinitions>
</Grid>

You can find out more about the Grid control from the Grid Class page on MSDN. You can also find out more about these container controls from the WPF Container Controls Overview page on MSDN.

Further resizing can be achieved using the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties. The default value of these properties is Stretch which will stretch elements to fit the size of their containing controls. However, when they are set to any other value, the elements will not stretch.

UPDATE >>>

In response to the questions in your comment:

Use the Grid.RowDefinition and Grid.ColumnDefinition settings to organise a basic structure first... it is common to add Grid controls into the cells of outer Grid controls if need be. You can also use the Grid.ColumnSpan and Grid.RowSpan properties to enable controls to span multiple columns and/or rows of a Grid.

It is most common to have at least one row/column with a Height/Width of "*" which will fill all remaining space, but you can have two or more with this setting, in which case the remaining space will be split between the two (or more) rows/columns. 'Auto' is a good setting to use for the rows/columns that are not set to '"*"', but it really depends on how you want the layout to be.

There is no Auto setting that you can use on the controls in the cells, but this is just as well, because we want the Grid to size the controls for us... therefore, we don't want to set the Height or Width of these controls at all.

The point that I made about the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties was just to let you know of their existence... as their default value is already Stretch, you don't generally need to set them explicitly.

The Margin property is generally just used to space your controls out evenly... if you drag and drop controls from the Visual Studio Toolbox, VS will set the Margin property to place your control exactly where you dropped it but generally, this is not what we want as it will mess with the auto sizing of controls. If you do this, then just delete or edit the Margin property to suit your needs.

use:

<div class="row form-group"></div>

On windows 10 Control Panel?Administrative Tools?Computer Management

It depends exactly what you're defining as "ASCII", but I would suggest trying a variant of a query like this:

SELECT * FROM tableName WHERE columnToCheck NOT REGEXP '[A-Za-z0-9]';

That query will return all rows where columnToCheck contains any non-alphanumeric characters. If you have other characters that are acceptable, add them to the character class in the regular expression. For example, if periods, commas, and hyphens are OK, change the query to:

SELECT * FROM tableName WHERE columnToCheck NOT REGEXP '[A-Za-z0-9.,-]';

The most relevant page of the MySQL documentation is probably 12.5.2 Regular Expressions.

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

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

Hope it helps!

You can use the codecs module, like this:

import codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sourceFileName, "r", "your-source-encoding") as sourceFile:
    with codecs.open(targetFileName, "w", "utf-8") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

EDIT: added BLOCKSIZE parameter to control file chunk size.

I can't comment on midopa's excellent answer due to lack of reputation.

On a Mac I (finally) successfully installed opencv from source using the following commands:

cmake -D CMAKE_BUILD_TYPE=RELEASE 
-D CMAKE_INSTALL_PREFIX=/usr/local 
-D PYTHON_EXECUTABLE=/Library/Frameworks/Python.framework/Versions/3.4/bin/python3 
-D PYTHON_LIBRARY=/Library/Frameworks/Python.framework//Versions/3.4/lib/libpython3.4m.dylib 
-D PYTHON_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m 
-D PYTHON_NUMPY_INCLUDE_DIRS=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/numpy/core/include/numpy 
-D PYTHON_PACKAGES_PATH=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages 
/relative/path/to/source/directory/

Then,

make -j8

change 8 for the number of threads your machine can handle, to speed things up

sudo make install

I added a PYTHONPATH environment variable to my ~/.bash_profile file so that Python could find cv2.so:

PYTHONPATH="${PYTHONPATH}:/usr/local/lib/python3.4/site-packages”
export PYTHONPATH

[For those using PyCharm, I had to go to Preferences > Project Structure > Add Content Root, and added the path to cv2.so's parent directory: /usr/local/lib/python3.4/site-packages]

This command got me past errors such as:

Could NOT find PythonLibs, by explicitly declaring the python library path

ld: can't link with a main executable for architecture x86_64
collect2: error: ld returned 1 exit status
make[2]: *** [lib/cv2.so] Error 1
make[1]: *** [modules/python2/CMakeFiles/opencv_python2.dir/all] Error 2
make: *** [all] Error 2

by explicitly pointing to the libpython3.4m.dylib

In terminal, check that it worked with:

$python3
>>> import cv2

It's all good if you don't get ImportError: No module named 'cv2'

This worked on a Macbook Pro Retina 15" 2013, Mavericks 10.9.4, Python 3.4.1 (previously installed from official download), opencv3 from source. Hope that this helps someone.

The primary difference between the two is the following

• typeof is a compile time construct and returns the type as defined at compile time
• typeid is a runtime construct and hence gives information about the runtime type of the value.

typeid Reference: https://en.wikipedia.org/wiki/Typeid

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

Got it from another answer but the script works magic. :)

You have to create a variable of the type of the class, and set it equal to a new instance of the object first.

GradeBook myGradeBook = new GradeBook();

Then call the method on the obect you just created.

myGradeBook.[method you want called]

<table cellpadding="pixels"cellspacing="pixels"></table>
<td align="position"valign="position"></td>

cellpadding="length in pixels" ~ The cellpadding attribute, used in the <table> tag, specifies how much blank space to display in between the content of each table cell and its respective border. The value is defined as a length in pixels. Hence, a cellpadding="10" attribute-value pair will display 10 pixels of blank space on all four sides of the content of each cell in that table.

cellspacing="length in pixels" ~ The cellspacing attribute, also used in the <table> tag, defines how much blank space to display in between adjacent table cells and in between table cells and the table border. The value is defined as a length in pixels. Hence, a cellspacing="10" attribute-value pair will horizontally and vertically separate all adjacent cells in the respective table by a length of 10 pixels. It will also offset all cells from the table's frame on all four sides by a length of 10 pixels.

Alternative to broadening permissions in your php config, you could change the user specified in your nginx config.

On the first line of your nginx.conf excerpt above, the user and group are specified as www and www, respectively.

user  www www;

Meanwhile, your php config probably specifies a user and group of www-data:

listen.owner = www-data
listen.group = www-data

You might change the line in your nginx.conf, to any of the following, then:

user www-data www;
user www-data www-data; # or any group, really, since you have the user matching
user www www-data; # requires that your php listen.mode gives rw access to the group

or alternatively you could not bother coding for it and use the 'conditional formatting' function in Excel which will set the background colour and font colour based on cell value.

There are only two variables here so set the default to yellow and then overwrite when the value is greater than or less than your threshold values.

Service:

import {Injectable, EventEmitter} from "@angular/core";    

@Injectable()
export class DataService {
onGetData: EventEmitter = new EventEmitter();

getData() {
  this.http.post(...params).map(res => {
    this.onGetData.emit(res.json());
  })
}

Component:

import {Component} from '@angular/core';    
import {DataService} from "../services/data.service";       
    
@Component()
export class MyComponent {
  constructor(private DataService:DataService) {
    this.DataService.onGetData.subscribe(res => {
      (from service on .emit() )
    })
  }

  //To send data to all subscribers from current component
  sendData() {
    this.DataService.onGetData.emit(--NEW DATA--);
  }
}

    public void invokeShare(Activity activity, String quote, String credit) {
    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, activity.getString(R.string.share_subject));
    shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Example text");    
    shareIntent.putExtra("com.facebook.platform.extra.APPLICATION_ID", activity.getString(R.string.app_id));                        
    activity.startActivity(Intent.createChooser(shareIntent, activity.getString(R.string.share_title)));
}

If you cannot use RowCounter for whatever reason, then a combination of these two filters should be an optimal way to get a count:

FirstKeyOnlyFilter() AND KeyOnlyFilter()

The FirstKeyOnlyFilter will result in the scanner only returning the first column qualifier it finds, as opposed to the scanner returning all of the column qualifiers in the table, which will minimize the network bandwith. What about simply picking one column qualifier to return? This would work if you could guarentee that column qualifier exists for every row, but if that is not true then you would get an inaccurate count.

The KeyOnlyFilter will result in the scanner only returning the column family, and will not return any value for the column qualifier. This further reduces the network bandwidth, which in the general case wouldn't account for much of a reduction, but there can be an edge case where the first column picked by the previous filter just happens to be an extremely large value.

I tried playing around with scan.setCaching but the results were all over the place. Perhaps it could help.

I had 16 million rows in between a start and stop that I did the following pseudo-empirical testing:

With FirstKeyOnlyFilter and KeyOnlyFilter activated:

    With caching not set (i.e., the default value), it took 188 seconds.
    With caching set to 1, it took 188 seconds
    With caching set to 10, it took 200 seconds
    With caching set to 100, it took 187 seconds
    With caching set to 1000, it took 183 seconds.
    With caching set to 10000, it took 199 seconds.
    With caching set to 100000, it took 199 seconds.

With FirstKeyOnlyFilter and KeyOnlyFilter disabled:

    With caching not set, (i.e., the default value), it took 309 seconds

I didn't bother to do proper testing on this, but it seems clear that the FirstKeyOnlyFilter and KeyOnlyFilter are good.

Moreover, the cells in this particular table are very small - so I think the filters would have been even better on a different table.

Here is a Java code sample:

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.util.Bytes;

import org.apache.hadoop.hbase.filter.RowFilter;
import org.apache.hadoop.hbase.filter.KeyOnlyFilter; 
import org.apache.hadoop.hbase.filter.FirstKeyOnlyFilter; 
import org.apache.hadoop.hbase.filter.FilterList;

import org.apache.hadoop.hbase.filter.CompareFilter.CompareOp;
import org.apache.hadoop.hbase.filter.RegexStringComparator; 

public class HBaseCount {
    public static void main(String[] args) throws IOException {
        Configuration config = HBaseConfiguration.create();

        HTable table = new HTable(config, "my_table");

        Scan scan = new Scan(
            Bytes.toBytes("foo"), Bytes.toBytes("foo~")
        );

        if (args.length == 1) {
            scan.setCaching(Integer.valueOf(args[0]));
        }
        System.out.println("scan's caching is " + scan.getCaching());

        FilterList allFilters = new FilterList();
        allFilters.addFilter(new FirstKeyOnlyFilter());
        allFilters.addFilter(new KeyOnlyFilter());

        scan.setFilter(allFilters);

        ResultScanner scanner = table.getScanner(scan);

        int count = 0;

        long start = System.currentTimeMillis();

        try {
            for (Result rr = scanner.next(); rr != null; rr = scanner.next()) {
                count += 1;
                if (count % 100000 == 0) System.out.println(count);
            }
        } finally {
            scanner.close();
        }

        long end = System.currentTimeMillis();

        long elapsedTime = end - start;

        System.out.println("Elapsed time was " + (elapsedTime/1000F));

    }
}

Here is a pychbase code sample:

    from pychbase import Connection
    c = Connection()
    t = c.table('my_table')
    # Under the hood this applies the FirstKeyOnlyFilter and KeyOnlyFilter
    # similar to the happybase example below
    print t.count(row_prefix="foo")

Here is a Happybase code sample:

    from happybase import Connection
    c = Connection(...)
    t = c.table('my_table')
    count = 0
    for _ in t.scan(filter='FirstKeyOnlyFilter() AND KeyOnlyFilter()'):
        count += 1

    print count

Thanks to @Tuckr and @KennyCason for the tip.

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

You need to tell Eclipse which JDK/JRE's you have installed and where they are located.

This is somewhat burried in the Eclipse preferences: In the Window-Menu select "Preferences". In the Preferences Tree, open the Node "Java" and select "Installed JRE's". Then click on the "Add"-Button in the Panel and select "Standard VM", "Next" and for "JRE Home" click on the "Directory"-Button and select the top level folder of the JDK you want to add.

Its easier than the description may make it look.

Code:

$string = "9,[email protected],8";

$array  = explode(",", $string);

print_r($array);

$no = 1;
foreach ($array as $line) {
    echo $no . ". " . $line . PHP_EOL;
    $no++;
};

As per Jeffrey Knight quote above, as soon as I run into situations where I need API calls to get something done, I tend to stop and ask myself "am I overcomplicating things?".

If what is wanted is to have some code and run it in Windows GUI mode or Console mode, consider moving the code used in both modes off to a code library DLL, and then having a Windows Forms application that uses that DLL, and a Console application that uses that DLL (i.e. if in Visual Studio you now have a three-project solution: library with the bulk of the code, GUI with just the Win Forms code, and Console with just your console code.)

file = open('Failed.py', 'w')
file.write('whatever')
file.close()

Here is a more pythonic version, which automatically closes the file, even if there was an exception in the wrapped block:

with open('Failed.py', 'w') as file:
    file.write('whatever')

Context is stored at the application level scope where as request is stored at page level i.e to say

Web Container brings up the applications one by one and run them inside its JVM. It stores a singleton object in its jvm where it registers anyobject that is put inside it.This singleton is shared across all applications running inside it as it is stored inside the JVM of the container itself.

However for requests, the container creates a request object that is filled with data from request and is passed along from one thread to the other (each thread is a new request that is coming to the server), also request is passed to the threads of same application.

try to use absolute url. if it not works, check if service's response has headers:

Access-Control-Allow-Origin and Access-Control-Allow-Headers

for example:

"Access-Control-Allow-Origin": "*"
"Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type, Accept"

Empty dictionaries evaluate to False in Python:

>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>

Thus, your isEmpty function is unnecessary. All you need to do is:

def onMessage(self, socket, message):
    if not self.users:
        socket.send("Nobody is online, please use REGISTER command" \
                    " in order to register into the server")
    else:
        socket.send("ONLINE " + ' ' .join(self.users.keys()))
