You might need to allow different combinations of data in your intent filter to get it to work in different cases (http/ vs https/, www. vs no www., etc).

For example, I had to do the following for an app which would open when the user opened a link to Google Drive forms (www.docs.google.com/forms)

Note that path prefix is optional.

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data android:scheme="http" />
            <data android:scheme="https" />

            <data android:host="www.docs.google.com" />
            <data android:host="docs.google.com" />

            <data android:pathPrefix="/forms" />
        </intent-filter>

You can use the get(index) method to access an element from a List.

Sets, by definition, simply contain elements and have no particular order. Therefore, there is no "first" element you can get, but it is possible to iterate through it using iterator (using the for each loop) or convert it to an array using the toArray() method.

How to set default values in twig: http://twig.sensiolabs.org/doc/filters/default.html

{{ my_var | default("my_var doesn't exist") }}

Or if you don't want it to display when null:

{{ my_var | default("") }}

Download make.exe from their official site GnuWin32

• In the Download session, click Complete package, except sources.

• Follow the installation instructions.

• Once finished, add the <installation directory>/bin/ to the PATH variable.

Now you will be able to use make in cmd.

User Defined Function.

1. Function must return a value.
2. Will allow only Select statements, it will not allow us to use DML statements.
3. It will allow only input parameters, doesn't support output parameters.
4. It will not allow us to use try-catch blocks.
5. Transactions are not allowed within functions.
6. We can use only table variables, it will not allow using temporary tables.
7. Stored Procedures can't be called from a function.
8. Functions can be called from a select statement.
9. A UDF can be used in join clause as a result set.

Stored Procedure

1. Stored Procedure may or not return values.
2. Can have select statements as well as DML statements such as insert, update, delete and so on
3. It can have both input and output parameters.
4. For exception handling we can use try catch blocks.
5. Can use transactions within Stored Procedures.
6. Can use both table variables as well as temporary table in it.
7. Stored Procedures can call functions.
8. Procedures can't be called from Select/Where/Having and so on statements. Execute/Exec statement can be used to call/execute Stored Procedure.
9. Procedures can't be used in Join clause

You can simply pass more arguments to summarise:

df %>% group_by(grp) %>% summarise(mean(a), mean(b), mean(c), mean(d))

Source: local data frame [3 x 5]

  grp  mean(a)  mean(b)  mean(c) mean(d)
1   1 2.500000 3.500000 2.000000     3.0
2   2 3.800000 3.200000 3.200000     2.8
3   3 3.666667 3.333333 2.333333     3.0

I tried experimenting with the answers given. My personal finding came out to be:

git rm -r --cached .

And then

git add .

This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.

The correct mechanism for C++ in anonymous namespaces. If you want something that is local to your file, you should use an anonymous namespace rather than the static modifier.

If you're using Devise, please note that

For Rails 5, protect_from_forgery is no longer prepended to the before_action chain, so if you have set authenticate_user before protect_from_forgery, your request will result in "Can't verify CSRF token authenticity." To resolve this, either change the order in which you call them, or use protect_from_forgery prepend: true.

Documentation

You could use eval:

eval(variablename + ".value = 'value'");

Review the pom.xml file inside of target/checkout/. Chances are, the pom.xml in your trunk or master branch does not have the distributionManagement tag.

Oh - the ugliness of Windows... Order of includes are important here. You need to include winsock2.h before windows.h. Since windows.h is probably included from your precompiled header (stdafx.h), you will need to include winsock2.h from there:

#include <winsock2.h>
#include <windows.h>

using json.loads will turn your data into a python dictionary.

Dictionaries values are accessed using ['key']

resp_str = {
  "name" : "ns1:timeSeriesResponseType",
  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",
  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",
  "value" : {
    "queryInfo" : {
      "creationTime" : 1349724919000,
      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",
      "criteria" : {
        "locationParam" : "[ALL:103232434]",
        "variableParam" : "[00060, 00065]"
      },
      "note" : [ {
        "value" : "[ALL:103232434]",
        "title" : "filter:sites"
      }, {
        "value" : "[mode=LATEST, modifiedSince=null]",
        "title" : "filter:timeRange"
      }, {
        "value" : "sdas01",
        "title" : "server"
      } ]
    }
  },
  "nil" : false,
  "globalScope" : true,
  "typeSubstituted" : false
}

would translate into a python diction

resp_dict = json.loads(resp_str)

resp_dict['name'] # "ns1:timeSeriesResponseType"

resp_dict['value']['queryInfo']['creationTime'] # 1349724919000

Converting HTML to PDF using ITextSharp

            //reading html code from html file
            FileStream fsHTMLDocument = new FileStream(htmlFileName, FileMode.Open, FileAccess.Read);
            StreamReader srHTMLDocument = new StreamReader(fsHTMLDocument);
            strHtml = srHTMLDocument.ReadToEnd();
            srHTMLDocument.Close();

            strHtml = strHtml.Replace("\r\n", "");
            strHtml = strHtml.Replace("\0", "");

You can download the sample file. Just place the html you want to convert in the files folder and run. It will automatically generate the pdf file and place it in the same folder. But in your case, you can specify your html path in the htmlFileName variable.

We can use

Type.GetType()

to get class name and can also create object of it using Activator.CreateInstance(type);

using System;
using System.Reflection;

namespace MyApplication
{
    class Application
    {
        static void Main()
        {
            Type type = Type.GetType("MyApplication.Action");
            if (type == null)
            {
                throw new Exception("Type not found.");
            }
            var instance = Activator.CreateInstance(type);
            //or
            var newClass = System.Reflection.Assembly.GetAssembly(type).CreateInstance("MyApplication.Action");
        }
    }

    public class Action
    {
        public string key { get; set; }
        public string Value { get; set; }
    }
}

Another trick is to place a invisible element above it. This will disable any hover effects as well

.myButton{
    position: absolute;
    display: none;
}

.myButton::after{ 
    position: absolute;
    content:"";
    height:100%;
    width:100%;
    top:0;
    left:0;
}

Try following solution and let me know in case of any issues:

driver.get('https://example.com/')
driver.switchTo().alert().sendKeys("username" + Keys.TAB + "password");
driver.switchTo().alert().accept();

This is working fine for me

lstpp is empty. You cant access the first element of an empty list.

In general, you can check if size > index.

In your case, you need to check if lstpp is empty. (you can use !lstpp.isEmpty())

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

string input = "Exemple of value between two string FirstString text I want to keep SecondString end of my string";
var match = Regex.Match(input, @"FirstString (.+?) SecondString ").Groups[1].Value;

If you are using Linux I suggest you to use the tee command. The implementation goes like this:

python python_file.py | tee any_file_name.txt

If you don't want to change anything in the code, I think this might be the best possible solution. You can also implement logger but you need do some changes in the code.

getElementById is defined by DOM Level 1 HTML to return null in the case no element is matched.

!==null is the most explicit form of the check, and probably the best, but there is no non-null falsy value that getElementById can return - you can only get null or an always-truthy Element object. So there's no practical difference here between !==null, !=null or the looser if (document.getElementById('xx')).

I don't think that is possible (though refer to the update below); as far as I know a table variable only exists within the scope that declared it. You can, however, use a temp table (use the create table syntax and prefix your table name with the # symbol), and that will be accessible within both the scope that creates it and the scope of your dynamic statement.

UPDATE: Refer to Martin Smith's answer for how to use a table-valued parameter to pass a table variable in to a dynamic SQL statement. Also note the limitation mentioned: table-valued parameters are read-only.

http://en.wikipedia.org/wiki/Byte_order_mark

The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. Its code point is U+FEFF. BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.

The BOM is a funky-looking character that you sometimes find at the start of unicode streams, giving a clue what the encoding is. It's usually handles invisibly by the string-handling stuff in Java, so you must have confused it somehow, but without seeing your code, it's hard to see where.

You might be able to fix it trivially by manually stripping the BOM from the string before feeding it to javac. It probably qualifies as whitespace, so try calling trim() on the input String, and feeding the output of that to javac.

You dont need to define option tags, you can do this using the ngOptions directive: https://docs.angularjs.org/api/ng/directive/ngOptions

<select class="form-control" ng-change="unitChanged()" ng-model="data.unit" ng-options="unit.id as unit.label for unit in units"></select>

ping -n 11 -w 1000 127.0.0.1 > nul

Update

Beginner's mistake. Ping doesn't wait 1000 ms before or after an request, but inbetween requests. So to wait 10 seconds, you'll have to do 11 pings to have 10 'gaps' of a second inbetween.

Specially for Android

For callback purposes I usually implement my own generic Runnable with input parameter(s):

public interface Runnable<TResult> {
    void run(TResult result);
}

Usage is simple:

myManager.doCallbackOperation(new Runnable<MyResult>() {
    @Override
    public void run(MyResult result) {
        // do something with the result
    }
});

In manager:

public void doCallbackOperation(Runnable<MyResult> runnable) {
    new AsyncTask<Void, Void, MyResult>() {
        @Override
        protected MyResult doInBackground(Void... params) {
            // do background operation
            return new MyResult(); // return resulting object
        }

        @Override
        protected void onPostExecute(MyResult result) {
            // execute runnable passing the result when operation has finished
            runnable.run(result);
        }
    }.execute();
}

Even we can refresh particular connection and in turn it will refresh all the pivots linked to it.

For this code I have created slicer from table present in Excel:

Sub UpdateConnection()
        Dim ServerName As String
        Dim ServerNameRaw As String
        Dim CubeName As String
        Dim CubeNameRaw As String
        Dim ConnectionString As String

        ServerNameRaw = ActiveWorkbook.SlicerCaches("Slicer_ServerName").VisibleSlicerItemsList(1)
        ServerName = Replace(Split(ServerNameRaw, "[")(3), "]", "")

        CubeNameRaw = ActiveWorkbook.SlicerCaches("Slicer_CubeName").VisibleSlicerItemsList(1)
        CubeName = Replace(Split(CubeNameRaw, "[")(3), "]", "")

        If CubeName = "All" Or ServerName = "All" Then
            MsgBox "Please Select One Cube and Server Name", vbOKOnly, "Slicer Info"
        Else
            ConnectionString = GetConnectionString(ServerName, CubeName)
            UpdateAllQueryTableConnections ConnectionString, CubeName
        End If
    End Sub

    Function GetConnectionString(ServerName As String, CubeName As String)
        Dim result As String
        result = "OLEDB;Provider=MSOLAP.5;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=" & CubeName & ";Data Source=" & ServerName & ";MDX Compatibility=1;Safety Options=2;MDX Missing Member Mode=Error;Update Isolation Level=2"

        GetConnectionString = result
    End Function

    Function GetConnectionString(ServerName As String, CubeName As String)
    Dim result As String
    result = "OLEDB;Provider=MSOLAP.5;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=" & CubeName & ";Data Source=" & ServerName & ";MDX Compatibility=1;Safety Options=2;MDX Missing Member Mode=Error;Update Isolation Level=2"
    GetConnectionString = result
End Function

Sub UpdateAllQueryTableConnections(ConnectionString As String, CubeName As String)
    Dim cn As WorkbookConnection

        For i = 0 To UBound(oTmp) - 1
            If InStr(1, oTmp(i), DBName, vbTextCompare) = 1 Then
                Set oledbCn = cn.OLEDBConnection
                oledbCn.SavePassword = True
                oledbCn.Connection = ConnectionString
                oledbCn.Refresh
                Count = Count + 1
            End If

    End If
End Sub

Using Moment.

I can't recommend the use of Moment enough. If you are able to use third-party libraries, I highly recommend doing so. Beyond just formatting, it deals with timezones, parsing, durations and time travel extremely well and will pay dividends in simplicity and time (at the small expense of size, abstraction and performance).

Usage

You wanted something that looked like this:

Friday 2:00pm 1 Feb 2013

Well, with Moment all you need you to do is this:

import Moment from "moment";

Moment().format( "dddd h:mma D MMM YYYY" ); //=> "Wednesday 9:20am 9 Dec 2020"

And if you wanted to match that exact date and time, all you would need to do is this:

import Moment from "moment";

Moment( "2013-2-1 14:00:00" ).format( "dddd h:mma D MMM YYYY" ) ); //=> "Friday 2:00pm 1 Feb 2013"

There's a myriad of other formatting options that can be found here.

Install

Go to their home page to see more detailed instructions, but if you're using npm or yarn it's as simple as:

npm install moment --save

or

yarn add moment

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

If you need to write semantically correct mark-up, even in HTML5, you must not use ' to escape single quotes. Although, I can imagine you actually meant apostrophe rather then single quote.

single quotes and apostrophes are not the same, semantically, although they might look the same.

Here's one apostrophe.

Use ' to insert it if you need HTML4 support. (edited)

In British English, single quotes are used like this:

"He told me to 'give it a try'", I said.

Quotes come in pairs. You can use:

<p><q>He told me to <q>give it a try</q></q>, I said.<p>

to have nested quotes in a semantically correct way, deferring the substitution of the actual characters to the rendering engine. This substitution can then be affected by CSS rules, like:

q {
  quotes: '"' '"' '<' '>';
} 

An old but seemingly still relevant article about semantically correct mark-up: The Trouble With EM ’n EN (and Other Shady Characters).

(edited) This used to be:

Use ’ to insert it if you need HTML4 support.

But, as @James_pic pointed out, that is not the straight single quote, but the "Single curved quote, right".

if you decide to fix this problem through the following configuration:

<mvc:annotation-driven>
  <mvc:message-converters register-defaults="true">
    <bean class="org.springframework.http.converter.StringHttpMessageConverter">
      <property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
    </bean>
  </mvc:message-converters>
</mvc:annotation-driven>

you should confirm that there should only one mvc:annotation-driven tag in all your *.xml file. otherwise, the configuration may not be effective.

data, _ := ioutil.ReadAll(response.Body)
fmt.Println(string(data))

android:background="?android:selectableItemBackground"
android:focusable="true"
android:clickable="true"

@Manuel was part way there. You can add the compiler option as well, like this:

If you have CMake 3.1.0+, this becomes even easier:

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
target_link_libraries(my_app PRIVATE Threads::Threads)

If you are using CMake 2.8.12+, you can simplify this to:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  target_compile_options(my_app PUBLIC "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

Older CMake versions may require:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  set_property(TARGET my_app PROPERTY COMPILE_OPTIONS "-pthread")
  set_property(TARGET my_app PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)

If you want to use one of the first two methods with CMake 3.1+, you will need set(THREADS_PREFER_PTHREAD_FLAG ON) there too.

You can write your possible date formats in array and parse date as following:

public static void Main(string[] args)
        {
            string dd = "12/31/2015"; //or 31/12/2015
            DateTime startDate;
            string[] formats = { "dd/MM/yyyy", "dd/M/yyyy", "d/M/yyyy", "d/MM/yyyy",
                                "dd/MM/yy", "dd/M/yy", "d/M/yy", "d/MM/yy", "MM/dd/yyyy"};
            
            DateTime.TryParseExact(dd, formats, 
            System.Globalization.CultureInfo.InvariantCulture,
            System.Globalization.DateTimeStyles.None, out startDate);
                
            Console.WriteLine(startDate.ToString("yyyy-MM-dd"));
            
        }

I ran into this problem after a firewall change to restrict access between our internal network and the database server reporting the error located in the DMZ. Communication was working fine until the change, and system and database restarts were of no help. In my case both Oracle XE11gR2 installations are on Windows.

After day of struggle I found http://edstevensdba.wordpress.com/2011/07/30/exploring-the-local_listener-parameter/ and solved the problem with:

alter system set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=[my server's ip])(PORT=1521))' scope=both;
alter system register;

it may be that this worked simply because of the 'alter system register' as suggested by ik_zelf. I did have the IP already set in relevant places in listener.ora and tnsnames.ora.

Programs return a 16 bit exit code. If the program was killed with a signal then the high order byte contains the signal used, otherwise the low order byte is the exit status returned by the programmer.

How that exit code is assigned to the status variable $? is then up to the shell. Bash keeps the lower 7 bits of the status and then uses 128 + (signal nr) for indicating a signal.

The only "standard" convention for programs is 0 for success, non-zero for error. Another convention used is to return errno on error.

My suggestion for dynamic JQuery Grid are below.

http://reconstrukt.com/ingrid/

https://github.com/mleibman/SlickGrid

http://www.datatables.net/index

Best one is :

On Ubuntu and Debian

apt-get install python-six

does the trick.

Use sudo apt-get install python-six if you get an error saying "permission denied".

Using junit4 and Hamcrest you get a concise method of comparing arrays. It also gives details of where the error is in the failure trace.

import static org.junit.Assert.*
import static org.hamcrest.CoreMatchers.*;

//...

assertThat(result, is(new int[] {56, 100, 2000}));

Failure Trace output:

java.lang.AssertionError: 
   Expected: is [<56>, <100>, <2000>]
   but: was [<55>, <100>, <2000>]

After you add some stuff... commit them and after all finished push it! BANG!! Start all problems... As you should notice there are some differences in the way both new and existent projects were defined. If some other person tries to add/commit/push same files, or content (git keep both as same objects), we will face the following error:

$ git push
Counting objects: 31, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (17/17), done.
Writing objects: 100% (21/21), 2.07 KiB | 0 bytes/s, done.
Total 21 (delta 12), reused 0 (delta 0)
remote: error: insufficient permission for adding an object to repository database ./objects  remote: fatal: failed to write object

To solve this problem you have to have something in mind operational system's permissions system as you are restricted by it in this case. Tu understand better the problem, go ahead and check your git object's folder (.git/objects). You will probably see something like that:

<your user_name>@<the machine name> objects]$ ls -la
total 200
drwxr-xr-x 25 <your user_name> <group_name> 2048 Feb 10 09:28 .
drwxr-xr-x  3 <his user_name> <group_name> 1024 Feb  3 15:06 ..
drwxr-xr-x  2 <his user_name> <group_name> 1024 Jan 31 13:39 02
drwxr-xr-x  2 <his user_name> <group_name> 1024 Feb  3 13:24 08

*Note that those file's permissions were granted only for your users, no one will never can changed it... *

Level       u   g   o
Permission rwx r-x ---
Binary     111 101 000
Octal       7   5   0

SOLVING THE PROBLEM

If you have super user permission, you can go forward and change all permissions by yourself using the step two, in any-other case you will need to ask all users with objects created with their users, use the following command to know who they are:

$ ls -la | awk '{print $3}' | sort -u 
<your user_name>
<his user_name>

Now you and all file's owner users will have to change those files permission, doing:

$ chmod -R 774 .

After that you will need to add a new property that is equivalent to --shared=group done for the new repository, according to the documentation, this make the repository group-writable, do it executing:

$ git config core.sharedRepository group

I'm using angular2-moment, but usage must be similar.

import { MomentModule } from "angular2-moment";
import moment = require("moment");

export class AppModule {

  constructor() {
    moment.locale('ru');
  }
}

You can also do the following:

CREATE TABLE #TEMPTABLE
(
    Column1 type1,
    Column2 type2,
    Column3 type3
)

INSERT INTO #TEMPTABLE
SELECT ...

SELECT *
FROM #TEMPTABLE ...

DROP TABLE #TEMPTABLE

I would suggest you have a look at BackgroundWorker. If you have a loop that large in your WinForm it will block and your app will look like it has hanged.

Look at BackgroundWorker.ReportProgress() to see how to report progress back to the UI thread.

For example:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;
    progressBar1.Value = 0;
    backgroundWorker.RunWorkerAsync();
}

private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);
        backgroundWorker.ReportProgress((j * 100) / 100000);
    }
}

private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // TODO: do something with final calculation.
}

$("#dropDownId").val(["130860","130858"]);
$("#dropDownId").selectmenu('refresh');

Some answers have already mentioned using various image libraries like Universal Image Loader and androidimageloader etc. This is an old quesion but for anyone still looking for something like this, there are several such libraries for image loading/caching.

Cited from https://unix.stackexchange.com/questions/50177/birth-is-empty-on-ext4/131347#131347 , the following shellscript would work to get creation time:

get_crtime() {
   for target in "${@}"; do
       inode=$(stat -c %i "${target}")
       fs=$(df "${target}"  | tail -1 | awk '{print $1}')
       crtime=$(sudo debugfs -R 'stat <'"${inode}"'>' "${fs}" 2>/dev/null | grep -oP 'crtime.*--\s*\K.*')
       printf "%s\t%s\n" "${target}" "${crtime}"
   done
}

1. Goto Blustacks settings > Preferences > Check Enable Android Debug Bridge (ADB)
2. Restart Bluestacks and Start Android Studio
3. Done

An Alternative is....

Convert both dates into milliseconds as below

Date d = new Date();
long l = d.getTime();

Now compare both long values

yourArray.indexOf(yourArrayKeyName) > -1

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple') > -1

true

fruit = ['apple', 'grapes', 'banana']

fruit.indexOf('apple1') > -1

false

In C99 (supported by clang and gcc) there's an obscure syntax for passing multi-dimensional arrays to functions by reference:

int l_matrix[10][20];

void test(int matrix_ptr[static 10][20]) {
}

int main(void) {
    test(l_matrix);
}

Unlike a plain pointer, this hints about array size, theoretically allowing compiler to warn about passing too-small array and spot obvious out of bounds access.

Sadly, it doesn't fix sizeof() and compilers don't seem to use that information yet, so it remains a curiosity.

import java.sql.Timestamp;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Util {
  public static Timestamp convertStringToTimestamp(String strDate) {
    try {
      DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
       // you can change format of date
      Date date = formatter.parse(strDate);
      Timestamp timeStampDate = new Timestamp(date.getTime());

      return timeStampDate;
    } catch (ParseException e) {
      System.out.println("Exception :" + e);
      return null;
    }
  }
}

To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space

    <View
        android:layout_width="0dp"
        android:layout_height="20dp"
        android:layout_weight="1" />

Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.

    <ImageButton
        android:id="@+id/btnGenesis"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center|center_vertical"
        android:layout_marginBottom="2dp"
        android:layout_marginLeft="0dp"
        android:layout_marginTop="2dp"
        android:background="@null"
        android:gravity="left"
        android:src="@drawable/prev" />

    <View
        android:layout_width="0dp"
        android:layout_height="20dp"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/lblVerseHeading"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:gravity="center"
        android:textSize="25sp" />

    <Spinner
        android:id="@+id/spinnerVerses"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:gravity="center"
        android:textSize="25sp" />

    <View
        android:layout_width="0dp"
        android:layout_height="20dp"
        android:layout_weight="1" />

    <ImageButton
        android:id="@+id/btnExodus"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center|center_vertical"
        android:layout_marginBottom="2dp"
        android:layout_marginLeft="0dp"
        android:layout_marginTop="2dp"
        android:background="@null"
        android:gravity="right"
        android:src="@drawable/next" />
</LinearLayout>

I would recommend taking a look at jQuery UI autocomplete widget. They handled most of the cases there since their code base is more mature than most ones out there.

Below is a link to a demo page so you can verify it works. http://jqueryui.com/demos/autocomplete/#default

You will get the most benefit from reading the source and seeing how they solved it. You can find it here: https://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.autocomplete.js.

Basically they do it all, they bind to input, keydown, keyup, keypress, focus and blur. Then they have special handling for all sorts of keys like page up, page down, up arrow key and down arrow key. A timer is used before getting the contents of the textbox. When a user types a key that does not correspond to a command (up key, down key and so on) there is a timer that explorers the content after about 300 milliseconds. It looks like this in the code:

// switch statement in the 
switch( event.keyCode ) {
            //...
            case keyCode.ENTER:
            case keyCode.NUMPAD_ENTER:
                // when menu is open and has focus
                if ( this.menu.active ) {
                    // #6055 - Opera still allows the keypress to occur
                    // which causes forms to submit
                    suppressKeyPress = true;
                    event.preventDefault();
                    this.menu.select( event );
                }
                break;
            default:
                suppressKeyPressRepeat = true;
                // search timeout should be triggered before the input value is changed
                this._searchTimeout( event );
                break;
            }
// ...
// ...
_searchTimeout: function( event ) {
    clearTimeout( this.searching );
    this.searching = this._delay(function() { // * essentially a warpper for a setTimeout call *
        // only search if the value has changed
        if ( this.term !== this._value() ) { // * _value is a wrapper to get the value *
            this.selectedItem = null;
            this.search( null, event );
        }
    }, this.options.delay );
},

The reason to use a timer is so that the UI gets a chance to be updated. When Javascript is running the UI cannot be updated, therefore the call to the delay function. This works well for other situations such as keeping focus on the textbox (used by that code).

So you can either use the widget or copy the code into your own widget if you are not using jQuery UI (or in my case developing a custom widget).

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

String called_from = getIntent().getStringExtra("called");

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

You can also set DirectoryIndex in apache's httpd.conf file.

CentOS keeps this file in /etc/httpd/conf/httpd.conf Debian: /etc/apache2/apache2.conf

Open the file in your text editor and find the line starting with DirectoryIndex

To load landing.html as a default (but index.html if that's not found) change this line to read:

DirectoryIndex  landing.html index.html

 HashMap<String, String> jsonToMap(String JsonDetectionString) throws JSONException {

    HashMap<String, String> map = new HashMap<String, String>();
    Gson gson = new Gson();

    map = (HashMap<String, String>) gson.fromJson(JsonDetectionString, map.getClass());

    return map;

}

Use for a date three days ago:

WHERE t.date >= DATE_ADD(CURDATE(), INTERVAL -3 DAY);

Check the DATE_ADD documentation.

Or you can use:

WHERE t.date >= ( CURDATE() - INTERVAL 3 DAY )

Even cleaner would be to just put p#given img { float: right } in the style sheet, or in the <head> and wrapped in style tags. Then, just use the markdown ![Alt text](/path/to/img.jpg).

WAR stands for Web application ARchive

JAR stands for Java ARchive

Follow all the steps.

Step 1: initialize git

$ git init

Step 2: Check files are exist or not.

$git ls

Step 3 : Add the file

$git add filename

Step 4: Add comment to show

$git commit -m "your comment"

Step 5: Link to your repository

$git remote add origin  "copy repository link  and paste here"

Step 6: Push on Git

$ git push -u origin master

If you are using Spring Security ver >= 4.2 you can use Spring Security's native support instead of including Apache's:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

The example above was copied from a Spring blog post in which you also can find information about how to configure CORS on a controller, specific controller methods, etc. Moreover, there is also XML configuration examples as well as Spring Boot integration.

Update from 10 years later In 2008 the hard drives you would run a database on would have much different characteristics and much higher cost than the disks you would store files on. These days there are much better solutions for storing files that didn't exist 10 years ago and I would revoke this advice and advise readers to look at some of the other answers in this thread.

Original

Don't store in images in the database unless you absolutely have to. I understand that this is not a web application, but if there isn't a shared file location that you can point to save the location of the file in the database.

//linuxserver/images/imagexxx.jpg

then perhaps you can quickly set up a webserver and store the web urls in the database (as well as the local path). While databases can handle LOB's and 3000 images (4-6 Megapixels, assuming 500K an image) 1.5 Gigs isn't a lot of space file systems are much better designed for storing large files than a database is.

User3550138 is correct. lonefy.vscode-js-css-html-formatter overrides all the settings mentioned in other answers. However, you don't have to disable or uninstall it as it can be configured.

Full instructions can be found by opening the extensions sidebar and clicking on this extension and it will display configuration instructions in the editor workspace. At least it does for me in Visual Studio Code version 1.14.1.

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

Since the question was "display" :

@Html.ValueFor(model => model.RegistrationDate, "{0:dd/MM/yyyy}")

No. You have to use is null and is not null in HQL.

PreparedStatements are the way to go, because they make SQL injection impossible. Here's a simple example taking the user's input as the parameters:

public insertUser(String name, String email) {
   Connection conn = null;
   PreparedStatement stmt = null;
   try {
      conn = setupTheDatabaseConnectionSomehow();
      stmt = conn.prepareStatement("INSERT INTO person (name, email) values (?, ?)");
      stmt.setString(1, name);
      stmt.setString(2, email);
      stmt.executeUpdate();
   }
   finally {
      try {
         if (stmt != null) { stmt.close(); }
      }
      catch (Exception e) {
         // log this error
      }
      try {
         if (conn != null) { conn.close(); }
      }
      catch (Exception e) {
         // log this error
      }
   }
}

No matter what characters are in name and email, those characters will be placed directly in the database. They won't affect the INSERT statement in any way.

There are different set methods for different data types -- which one you use depends on what your database fields are. For example, if you have an INTEGER column in the database, you should use a setInt method. The PreparedStatement documentation lists all the different methods available for setting and getting data.

import org.springframework.core.io.ClassPathResource;

...

File folder = new ClassPathResource("sql").getFile();
File[] listOfFiles = folder.listFiles();

It is worth noting that this will limit your deployment options, ClassPathResource.getFile() only works if the container has exploded (unzipped) your war file.

<form id="myform">
    <input type="textbox" id="field"/>
    <input type="button" value="submit">
</form>

<script>
    $(function () {
        $("#field").keyup(function (event) {
            if (event.which === 13) {
                document.myform.submit();
            }
        }
    });
</script>

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

Another solution but without using ng-click which still works even for other tags than <a>:

<tr [routerLink]="['/about']">

This way you can also pass parameters to your route: https://stackoverflow.com/a/40045556/838494

(This is my first day with angular. Gentle feedback is welcome)

You can use a FileReader object to read text file here is example code:

  <div id="page-wrapper">

        <h1>Text File Reader</h1>
        <div>
            Select a text file: 
            <input type="file" id="fileInput">
        </div>
        <pre id="fileDisplayArea"><pre>

    </div>
<script>
window.onload = function() {
        var fileInput = document.getElementById('fileInput');
        var fileDisplayArea = document.getElementById('fileDisplayArea');

        fileInput.addEventListener('change', function(e) {
            var file = fileInput.files[0];
            var textType = /text.*/;

            if (file.type.match(textType)) {
                var reader = new FileReader();

                reader.onload = function(e) {
                    fileDisplayArea.innerText = reader.result;
                }

                reader.readAsText(file);    
            } else {
                fileDisplayArea.innerText = "File not supported!"
            }
        });
}

</script>

Here is the codepen demo

If you have a fixed file to read every time your application load then you can use this code :

<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function ()
    {
        if(rawFile.readyState === 4)
        {
            if(rawFile.status === 200 || rawFile.status == 0)
            {
                var allText = rawFile.responseText;
                fileDisplayArea.innerText = allText 
            }
        }
    }
    rawFile.send(null);
}

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

Get the entire record as you want using the condition with inner select query.

SELECT *
FROM   member
WHERE  email IN (SELECT email
                 FROM   member
                 WHERE  login_id = [email protected]) 

In python 3, to get text output:

import io
import urllib.request

response = urllib.request.urlopen("http://google.com")
text = io.TextIOWrapper(response)

Simply copy the file, add and commit it:

cp dir1/A.txt dir2/A.txt
git add dir2/A.txt
git commit -m "Duplicated file from dir1/ to dir2/"

Then the following commands will show the full pre-copy history:

git log --follow dir2/A.txt

To see inherited line-by-line annotations from the original file use this:

git blame -C -C -C dir2/A.txt

Git does not track copies at commit-time, instead it detects them when inspecting history with e.g. git blame and git log.

Most of this information comes from the answers here: Record file copy operation with Git

Bootstrap 4

The carousel has changed in 4.x, and the multi-slide animation transitions can be overridden like this...

.carousel-inner .carousel-item-right.active,
.carousel-inner .carousel-item-next {
  transform: translateX(33.33%);
}

.carousel-inner .carousel-item-left.active, 
.carousel-inner .carousel-item-prev {
  transform: translateX(-33.33%)
}

.carousel-inner .carousel-item-right,
.carousel-inner .carousel-item-left{ 
  transform: translateX(0);
}

Bootstrap 4 Alpha.6 Demo
Bootstrap 4.0.0 (show 4, advance 1 at a time)
Bootstrap 4.1.0 (show 3, advance 1 at a time)
Bootstrap 4.1.0 (advance all 4 at once)
Bootstrap 4.3.1 responsive (show multiple, advance 1)new
Bootstrap 4.3.1 carousel with cardsnew

Another option is a responsive carousel that only shows and advances 1 slide on smaller screens, but shows multiple slides are larger screens. Instead of cloning the slides like the previous example, this one adjusts the CSS and use jQuery only to move the extra slides to allow for continuous cycling (wrap around):

Please don't just copy-and-paste this code. First, understand how it works.

Bootstrap 3

Here is a 3.x example on Bootply: http://bootply.com/89193

You need to put an entire row of images in the item active. Here is another version that doesn't stack the images at smaller screen widths: http://bootply.com/92514

EDIT Alternative approach to advance one slide at a time:

Use jQuery to clone the next items..

$('.carousel .item').each(function(){
  var next = $(this).next();
  if (!next.length) {
    next = $(this).siblings(':first');
  }
  next.children(':first-child').clone().appendTo($(this));

  if (next.next().length>0) {
    next.next().children(':first-child').clone().appendTo($(this));
  }
  else {
    $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
  }
});

And then CSS to position accordingly...

Before 3.3.1

.carousel-inner .active.left { left: -33%; }
.carousel-inner .next        { left:  33%; }

After 3.3.1

.carousel-inner .item.left.active {
  transform: translateX(-33%);
}
.carousel-inner .item.right.active {
  transform: translateX(33%);
}

.carousel-inner .item.next {
  transform: translateX(33%)
}
.carousel-inner .item.prev {
  transform: translateX(-33%)
}

.carousel-inner .item.right,
.carousel-inner .item.left { 
  transform: translateX(0);
}

This will show 3 at time, but only slide one at a time:

Please don't copy-and-paste this code. First, understand how it works. This answer is here to help you learn.

Doubling up this modified bootstrap 4 carousel only functions half correctly (scroll loop stops working)
how to make 2 bootstrap sliders in single page without mixing their css and jquery?
Bootstrap 4 Multi Carousel show 4 images instead of 3

All answers look a bit to big. I just use:

if (SYSTEM_VERSION_GREATER_THAN(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_EQUAL_TO(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_LESS_THAN(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(@"7.0")){(..CODE...)}

Of course replace the @"7.0" with your required OS version.

You can append to your PATH in a minimal fashion. No need for parentheses unless you're appending more than one element. It also usually doesn't need quotes. So the simple, short way to append is:

path+=/some/new/bin/dir

This lower-case syntax is using path as an array, yet also affects its upper-case partner equivalent, PATH (to which it is "bound" via typeset).

(Notice that no : is needed/wanted as a separator.)

Common interactive usage

Then the common pattern for testing a new script/executable becomes:

path+=$PWD/.
# or
path+=$PWD/bin

Common config usage

You can sprinkle path settings around your .zshrc (as above) and it will naturally lead to the earlier listed settings taking precedence (though you may occasionally still want to use the "prepend" form path=(/some/new/bin/dir $path)).

Related tidbits

Treating path this way (as an array) also means: no need to do a rehash to get the newly pathed commands to be found.

Also take a look at vared path as a dynamic way to edit path (and other things).

You may only be interested in path for this question, but since we're talking about exports and arrays, note that arrays generally cannot be exported.

You can even prevent PATH from taking on duplicate entries (refer to this and this):

typeset -U path

You can do it using remote debugging, here is official documentation. Basic process:

1. Connect your android device
2. Select your device: More tools > Inspect devices* from dev tools on pc/mac.
3. Authorize on your mobile.
4. Happy debugging!!

* This is now "Remote devices".

We may need more information. Here is what I did to reproduce on SQL Server 2008:

CREATE DATABASE [Test] ON  PRIMARY 
    ( 
    NAME = N'Test'
    , FILENAME = N'...Test.mdf' 
    , SIZE = 3072KB 
    , FILEGROWTH = 1024KB 
    )
    LOG ON 
    ( 
    NAME = N'Test_log'
    , FILENAME = N'...Test_log.ldf' 
    , SIZE = 1024KB 
    , FILEGROWTH = 10%
    )
    COLLATE SQL_Latin1_General_CP850_BIN2
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[MyTable]
    (
    [SomeCol] [varchar](50) NULL
    ) ON [PRIMARY]
GO
Insert MyTable( SomeCol )
Select '±' Collate SQL_Latin1_General_CP1_CI_AS
GO
Select SomeCol, SomeCol Collate SQL_Latin1_General_CP1_CI_AS
From MyTable

Results show the original character. Declaring collation in the query should return the proper character from SQL Server's perspective however it may be the case that the presentation layer is then converting to something yet different like UTF-8.

Here are the steps:

1. Start the command line.
2. Enter the folder containing the .m file with cd C:\M1\M2\M3
3. Run the following: C:\E1\E2\E3\matlab.exe -r mfile

Windows systems will use your current folder as the location for MATLAB to search for .m files, and the -r option tries to start the given .m file as soon as startup occurs.

For GCC, this is accomplished in two stages:

First compile the data but tell the compiler to separate the code into separate sections within the translation unit. This will be done for functions, classes, and external variables by using the following two compiler flags:

-fdata-sections -ffunction-sections

Link the translation units together using the linker optimization flag (this causes the linker to discard unreferenced sections):

-Wl,--gc-sections

So if you had one file called test.cpp that had two functions declared in it, but one of them was unused, you could omit the unused one with the following command to gcc(g++):

gcc -Os -fdata-sections -ffunction-sections test.cpp -o test -Wl,--gc-sections

(Note that -Os is an additional compiler flag that tells GCC to optimize for size)

If you want multiple string replacement:

NSString *s = @"foo/bar:baz.foo";
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"/:."];
s = [[s componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];
NSLog(@"%@", s); // => foobarbazfoo

It's for your UPDATE question.

Since you cannot have two methods with the same name and signature you have to use the ActionName attribute:

UPDATE:

[HttpGet]
public ActionResult FirstAjax()
{
    Some Code--Some Code---Some Code
    return View();
}

[HttpPost]
[ActionName("FirstAjax")]
public ActionResult FirstAjaxPost()
{
    Some Code--Some Code---Some Code
    return View();
}

And please refer this link for further reference of how a method becomes an action. Very good reference though.

JavaScript Solution

<select id="comboA">
<option value="">Select combo</option>
<option value="Value1">Text1</option>
<option value="Value2">Text2</option>
<option value="Value3">Text3</option>
</select>

<script>
 document.getElementById("comboA").onchange = function(){
    var value = document.getElementById("comboA").value;
 };
</script>

or

<script>
 document.getElementById("comboA").onchange = function(evt){
    var value = evt.target.value;
 };
</script>

or

<script>
 document.getElementById("comboA").onchange = handleChange;

 function handleChange(evt){
    var value = evt.target.value;
 };
</script>

The easiest way to draw a relationship between items is by understanding them in plain languages. Example

A user can have many cars but then a car can have just one owner. After establishing this, the foreign key should be used on the item with the many relationship. In this case the car. Meaning you'll include user as a foreign key in cars

And a one on one relationship is quite simple. Say a man and a heart. A man has only one heart and a heart can belong to just one man

Using C# 6.0 (which allows expression bodied functions and null propagation), for LINQ to Objects, it can be done in a single line like this (also checking for null):

public static bool ContainsInsensitive(this string str, string value) => str?.IndexOf(value, StringComparison.OrdinalIgnoreCase) >= 0;

VLookup

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

If you want to see dependencies on project and all subprojects use in your top-level build.gradle:

subprojects {
    task listAllDependencies(type: DependencyReportTask) {}
}

Then call gradle:

gradle listAllDependencies

I had an applicationhost.config inside my project folder. It seems IISExpress uses this folder, even though it displays a different file in my c:\users folder

.vs\config\applicationhost.config

Use a packet analyzer to intercept the packets to/from somewhere.com. Studying those packets should tell you what is going on.

Time-outs or connections refused could mean that the remote host is too busy.

The updated or deleted values are stored in DELETED. we can get it by the below method in trigger

Full example,

CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE 
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)

SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED

END

Thought I'd add an answer since your question title looks like it is asking how to create or update, rather than get or create as described in the question body.

If you did want to create or update an object, the .save() method already has this behaviour by default, from the docs:

Django abstracts the need to use INSERT or UPDATE SQL statements. Specifically, when you call save(), Django follows this algorithm:

If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.

It's worth noting that when they say 'if the UPDATE didn't update anything' they are essentially referring to the case where the id you gave the object doesn't already exist in the database.

Python dictionary was unordered before Python 3.6. In CPython implementation of Python 3.6, dictionary keeps the insertion order. From Python 3.7, this will become a language feature.

In changelog of Python 3.6 (https://docs.python.org/3.6/whatsnew/3.6.html#whatsnew36-compactdict):

The order-preserving aspect of this new implementation is considered an implementation detail and should not be relied upon (this may change in the future, but it is desired to have this new dict implementation in the language for a few releases before changing the language spec to mandate order-preserving semantics for all current and future Python implementations; this also helps preserve backwards-compatibility with older versions of the language where random iteration order is still in effect, e.g. Python 3.5).

In document of Python 3.7 (https://docs.python.org/3.7/tutorial/datastructures.html#dictionaries):

Performing list(d) on a dictionary returns a list of all the keys used in the dictionary, in insertion order (if you want it sorted, just use sorted(d) instead).

So unlike previous versions, you can sort a dict after Python 3.6/3.7. If you want to sort a nested dict including the sub-dict inside, you can do:

test_dict = {'a': 1, 'c': 3, 'b': {'b2': 2, 'b1': 1}}

def dict_reorder(item):
    return {k: sort_dict(v) if isinstance(v, dict) else v for k, v in sorted(item.items())}

reordered_dict = dict_reorder(test_dict)

What you're talking about is becoming a payment service provider. I have been there and done that. It was a lot easier about 10 years ago than it is now, but if you have a phenomenal amount of time, money and patience available, it is still possible.

You will need to contact an acquiring bank. You didnt say what region of the world you are in, but by this I dont mean a local bank branch. Each major bank will generally have a separate card acquiring arm. So here in the UK we have (eg) Natwest bank, which uses Streamline (or Worldpay) as its acquiring arm. In total even though we have scores of major banks, they all end up using one of five or so card acquirers.

Happily, all UK card acquirers use a standard protocol for communication of authorisation requests, and end of day settlement. You will find minor quirks where some acquiring banks support some features and have slightly different syntax, but the differences are fairly minor. The UK standards are published by the Association for Payment Clearing Services (APACS) (which is now known as the UKPA). The standards are still commonly referred to as APACS 30 (authorization) and APACS 29 (settlement), but are now formally known as APACS 70 (books 1 through 7).

Although the APACS standard is widely supported across the UK (Amex and Discover accept messages in this format too) it is not used in other countries - each country has it's own - for example: Carte Bancaire in France, CartaSi in Italy, Sistema 4B in Spain, Dankort in Denmark etc. An effort is under way to unify the protocols across Europe - see EPAS.org

Communicating with the acquiring bank can be done a number of ways. Again though, it will depend on your region. In the UK (and most of Europe) we have one communications gateway that provides connectivity to all the major acquirers, they are called TNS and there are dozens of ways of communicating through them to the acquiring bank, from dialup 9600 baud modems, ISDN, HTTPS, VPN or dedicated line. Ultimately the authorisation request will be converted to X25 protocol, which is the protocol used by these acquiring banks when communicating with each other.

In summary then: it all depends on your region.

• Contact a major bank and try to get through to their card acquiring arm.
• Explain that you're setting up as a payment service provider, and request details on comms format for authorization requests and end of day settlement files
• Set up a test merchant account and develop auth/settlement software and go through the accreditation process. Most acquirers help you through this process for free, but when you want to register as an accredited PSP some will request a fee.
• you will need to comply with some regulations too, for example you may need to register as a payment institution

Once you are registered and accredited you'll then be able to accept customers and set up merchant accounts on behalf of the bank/s you're accredited against (bearing in mind that each acquirer will generally support multiple banks). Rinse and repeat with other acquirers as you see necessary.

Beyond that you have lots of other issues, mainly dealing with PCI-DSS. Thats a whole other topic and there are already some q&a's on this site regarding that. Like I say, its a phenomenal undertaking - most likely a multi-year project even for a reasonably sized team, but its certainly possible.

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

You can just modified the .bash_profile by adding the MySQL $PATH as the following:
export PATH=$PATH:/usr/local/mysql/bin.

I did the following:

1- Open Terminal then $ nano .bash_profile or $ vim .bash_profile

2- Add the following PATH code to the .bash_profile

# Set architecture flags
export ARCHFLAGS="-arch x86_64"
# Ensure user-installed binaries take precedence
export PATH=/usr/local/mysql/bin:$PATH
# Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc 

3- Save the file.

4- Refresh Terminal using $ source ~/.bash_profile

5- To verify, type in Terminal $ mysql --version

6- It should print the output something like this:

$ mysql Ver 14.14 Distrib 5.7.17, for macos10.12 (x86_64)

The Terminal is now configured to read the MySQL commands from $PATH which is placed in the .bash_profile .

The following is more Drupal-ish:

url(current_path(), array('absolute' => true)); 

The padding options padx and pady of the grid and pack methods can take a 2-tuple that represent the left/right and top/bottom padding.

Here's an example:

import tkinter as tk

class MyApp():
    def __init__(self):
        self.root = tk.Tk()
        l1 = tk.Label(self.root, text="Hello")
        l2 = tk.Label(self.root, text="World")
        l1.grid(row=0, column=0, padx=(100, 10))
        l2.grid(row=1, column=0, padx=(10, 100)) 

app = MyApp()
app.root.mainloop()

Use the convert function, for example:

select * from data 
where dateVal < convert(datetime, '01/01/2008', 103)

Where the convert style (103) determines the date format to use.

SQLite lets you use it in memory.

Take a look at this Github issue:

https://github.com/facebook/react-native/issues/231

They are trying to require non-JSON files, in particular JSON. There is no method of doing this right now, so you either have to use AsyncStorage as @CocoOS mentioned, or you could write a small native module to do what you need to do.

I had this same problem and resolved it by making sure all references to the previous version of crystal from the Web Config file, the server, and the publishing workstation were removed. Other than the full trust basically everything that user707217 did, I did and it worked for my upgraded Web application

"a"[0]

or

?a

Both would return their ASCII equivalent.

I want to work with exec_query of the ActiveRecord class, because it returns the mapping of the query transforming into object, so it gets very practical and productive to iterate with the objects when the subject is Raw SQL.

Example:

values = ActiveRecord::Base.connection.exec_query("select * from clients")
p values

and return this complete query:

[{"id": 1, "name": "user 1"}, {"id": 2, "name": "user 2"}, {"id": 3, "name": "user 3"}]

To get only list of values

p values.rows

[[1, "user 1"], [2, "user 2"], [3, "user 3"]]

To get only fields columns

p values.columns

["id", "name"]

In my case,this error happen when I use the Floating action button and set android:backgroundTint="#000". Then just don't set backgroundTint and problem solved. Hope it's helpful for you.

If you want to combine using AND (intersection), use merge:

first_name_relation.merge(last_name_relation)

If you want to combine using OR (union), use or^†:

first_name_relation.or(last_name_relation)

^† Only in ActiveRecord 5+; for 4.2 install the where-or backport.

It worked for me:

Template HTML:

I added (ngModelChange)="selectChange($event)" to my select.

<div>
  <label for="myListOptions">My List Options</label>
  <select (ngModelChange)="selectChange($event)" [(ngModel)]=model.myListOptions.id >
    <option *ngFor="let oneOption of listOptions" [ngValue]="oneOption.id">{{oneOption.name}}</option>
  </select>
</div>

On component.ts:

  listOptions = [
    { id: 0, name: "Perfect" },
    { id: 1, name: "Low" },
    { id: 2, name: "Minor" },
    { id: 3, name: "High" },
  ];

An you need add to component.ts this function:

  selectChange( $event) {
    //In my case $event come with a id value
    this.model.myListOptions = this.listOptions[$event];
  }

Note: I try with [select]="oneOption.id==model.myListOptions.id" and not work.

============= Another ways can be: =========

Template HTML:

I added [compareWith]="compareByOptionId to my select.

<div>
  <label for="myListOptions">My List Options</label>
  <select [(ngModel)]=model.myListOptions [compareWith]="compareByOptionId">
    <option *ngFor="let oneOption of listOptions" [ngValue]="oneOption">{{oneOption.name}}</option>
  </select>
</div>

On component.ts:

  listOptions = [
    { id: 0, name: "Perfect" },
    { id: 1, name: "Low" },
    { id: 2, name: "Minor" },
    { id: 3, name: "High" },
  ];

An you need add to component.ts this function:

 /* Return true or false if it is the selected */
 compareByOptionId(idFist, idSecond) {
    return idFist && idSecond && idFist.id == idSecond.id;
 }

Have added ErrorHandler to this in case the user hits the cancel button instead of selecting a folder. So instead of getting a horrible error message you get a message that a folder must be selected and then the routine ends. Below code also stores the folder path in a range name (Which is just linked to cell A1 on a sheet).

Sub SelectFolder()

Dim diaFolder As FileDialog

'Open the file dialog
On Error GoTo ErrorHandler
Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
diaFolder.AllowMultiSelect = False
diaFolder.Title = "Select a folder then hit OK"
diaFolder.Show
Range("IC_Files_Path").Value = diaFolder.SelectedItems(1)
Set diaFolder = Nothing
Exit Sub

ErrorHandler:
Msg = "No folder selected, you must select a folder for program to run"
Style = vbError
Title = "Need to Select Folder"
Response = MsgBox(Msg, Style, Title)

End Sub

The Global Assembly Cache (GAC) is a folder in Windows directory to store the .NET assemblies that are specifically designated to be shared by all applications executed on a system. Assemblies can be shared among multiple applications on the machine by registering them in global Assembly cache(GAC). GAC is a machine wide a local cache of assemblies maintained by the .NET Framework.

VERY IMPORTANT Additional info on difference between .text() and .html():

If your selector selects more than one item, e.g you have two spans like so <span class="foo">bar1</span> <span class="foo">bar2</span> ,

then

$('.foo').text(); appends the two texts and give you that; whereas

$('.foo').html(); gives you only one of those.

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

So if I get it right, on click of a button, you want to open up a modal that lists the values entered by the users followed by submitting it.

For this, you first change your input type="submit" to input type="button" and add data-toggle="modal" data-target="#confirm-submit" so that the modal gets triggered when you click on it:

<input type="button" name="btn" value="Submit" id="submitBtn" data-toggle="modal" data-target="#confirm-submit" class="btn btn-default" />

Next, the modal dialog:

<div class="modal fade" id="confirm-submit" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                Confirm Submit
            </div>
            <div class="modal-body">
                Are you sure you want to submit the following details?

                <!-- We display the details entered by the user here -->
                <table class="table">
                    <tr>
                        <th>Last Name</th>
                        <td id="lname"></td>
                    </tr>
                    <tr>
                        <th>First Name</th>
                        <td id="fname"></td>
                    </tr>
                </table>

            </div>

            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a href="#" id="submit" class="btn btn-success success">Submit</a>
            </div>
        </div>
    </div>
</div>

Lastly, a little bit of jQuery:

$('#submitBtn').click(function() {
     /* when the button in the form, display the entered values in the modal */
     $('#lname').text($('#lastname').val());
     $('#fname').text($('#firstname').val());
});

$('#submit').click(function(){
     /* when the submit button in the modal is clicked, submit the form */
    alert('submitting');
    $('#formfield').submit();
});

You haven't specified what the function validateForm() does, but based on this you should restrict your form from being submitted. Or you can run that function on the form's button #submitBtn click and then load the modal after the validations have been checked.

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

The question is pretty old, but nowadays you can use forEach, which is efficient and will retain the keys as numbers:

let keys = widthRange.map((v,k) => k).filter(i=>i!==undefined))

This loops through widthRange and makes a new array with the value of the keys, and then filters out all sparce slots by only taking the values that are defined.

(Bad idea, but for thorughness: If slot 0 was always empty, that could be shortened to filter(i=>i) or filter(Boolean)

And, it may be less efficient, but the numbers can be cast with let keys = Object.keys(array).map(i=>i*1)

To answer your question posted in the title of this topic...

Step 1--> Right Click on Java Project, Select the option "Properties"

Step 2--> Select "Java Build Path" from the left side menu, make sure you are on "Source" tab, click "Add Folder"

Step 3--> Click the option "Create New Folder..." available at the bottom of the window

Step 4--> Enter the name of the new folder as "resources" and then click "Finish"

Step 5--> Now you'll be able to see the newly created folder "resources" under your java project, Click "Ok", again Click "Ok"

Final Step --> Now you should be able to see the new folder "resources" under your java project

you can use like this:

string Log_In_Val = (Convert.ToString(attenObj.Log_In) == "" ? "Null" + "," : "'" + Convert.ToString(attenObj.Log_In) + "',");

Here my extended version of Oleksandr Shpota's answer, including the imports. The package org.apache.http.* can be found in org.apache.httpcomponents:httpclient. I've commented the changes:

There are many ways to do this. My favorite way is:

1. Add a mod_user field to your source table (the one you want to log).

2. Create a log table that contains the fields you want to log, plus a log_datetime and seq_num field. seq_num is the primary key.

3. Build a trigger on the source table that inserts the current record into the log table whenever any monitored field is changed.

Now you've got a record of every change and who made it.

• SAP SE is a German multinational that makes enterprise software. It is best known for SAP ERP and its predecessors (SAP R/2 & SAP R/3). As the name suggests, SAP ERP is an ERP system, which basically means that it supports a wide range of business processes from warehouse management and sales to HR, business intelligence, etc.
  
  Although SAP ERP isn't the only software sold by SAP, people are typically refering to SAP ERP when they say "they're using SAP at work". It's important to note, though, that SAP is the name of the company and no software is sold or licensed as just "SAP".

• ABAP is a 4GL programming language created by SAP, and commonly compared with OpenEdge ABL or COBOL. Much of SAP's software is written in ABAP. SAP provides an ABAP Workbench, which is a collection of tools that allows third party developers to develop, test and run custom ABAP programs within the SAP ERP system. The ABAP Workbench is typically used only when business logic cannot be implemented in SAP ERP by means of mere configuration.

Looking at the AndroidManifest.xml (link), on line 9:

<activity android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden" android:name="VncCanvasActivity">

This line specifies the screenOrientation as landscape, but author goes further in overriding any screen orientation changes with configChanges="orientation|keyboardHidden". This points to a overridden function in VncCanvasActivity.java.

If you look at VncCanvasActivity, on line 109 is the overrided function:

@Override
public void onConfigurationChanged(Configuration newConfig) {
  // ignore orientation/keyboard change
  super.onConfigurationChanged(newConfig);
}

The author specifically put a comment to ignore any keyboard or orientation changes.

If you want to change this, you can go back to the AndroidManifest.xml file shown above, and change the line to:

<activity android:screenOrientation="sensor" android:name="VncCanvasActivity">

This should change the program to switch from portrait to landscape when the user rotates the device.

This may work, but might mess up how the GUI looks, depending on how the layout were created. You will have to account for that. Also, depending on how the activities are coded, you may notice that when screen orientation is changed, the values that were filled into any input boxes disappear. This also may have to be handled.

Interestingly virtually all answers revolve around XPath's function contains(), neglecting the fact it is case sensitive - contrary to the OP's ask.

If you need case insensitivity, that is achievable in XPath 1.0 (the version contemporary browsers support), though it's not pretty - by using the translate() function. It substitutes a source character to its desired form, by using a translation table.

Constructing a table of all upper case characters will effectively transform the node's text to its lower() form - allowing case-insensitive matching (here's just the prerogative):

[
  contains(
    translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),
    'my button'
  )
]
# will match a source text like "mY bUTTon"

The full Python call:

driver.find_elements_by_xpath("//*[contains(translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ?', 'abcdefghijklmnopqrstuvwxyz?'), 'my button')]")

Naturally this approach has its drawbacks - as given, it'll work only for Latin text; if you want to cover Unicode characters - you'll have to add them to the translation table. I've done that in the sample above - the last character is the Cyrillic symbol "?".

And if we lived in a world where browsers supported XPath 2.0 and up (, but not happening any time soon ??), we could having used the functions lower-case() (yet, not fully locale-aware), and matches (for regex searches, with the case-insensitive ('i') flag).

Below command will display the modfied files alone in windows.

svn status | findstr "^M"

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

Print a unicode character in Python:

Print a unicode character directly from python interpreter:

el@apollo:~$ python
Python 2.7.3
>>> print u'\u2713'
?

Unicode character u'\u2713' is a checkmark. The interpreter prints the checkmark on the screen.

Print a unicode character from a python script:

Put this in test.py:

#!/usr/bin/python
print("here is your checkmark: " + u'\u2713');

Run it like this:

el@apollo:~$ python test.py
here is your checkmark: ?

If it doesn't show a checkmark for you, then the problem could be elsewhere, like the terminal settings or something you are doing with stream redirection.

Store unicode characters in a file:

Save this to file: foo.py:

#!/usr/bin/python -tt
# -*- coding: utf-8 -*-
import codecs
import sys 
UTF8Writer = codecs.getwriter('utf8')
sys.stdout = UTF8Writer(sys.stdout)
print(u'e with obfuscation: é')

Run it and pipe output to file:

python foo.py > tmp.txt

Open tmp.txt and look inside, you see this:

el@apollo:~$ cat tmp.txt 
e with obfuscation: é

Thus you have saved unicode e with a obfuscation mark on it to a file.

Satisfies all your requirements if you use the trick told below

Regex: /^(\+\d{1,3}[- ]?)?\d{10}$/

1. ^ start of line
2. A + followed by \d+ followed by a or - which are optional.
3. Whole point two is optional.
4. Negative lookahead to make sure 0s do not follow.
5. Match \d+ 10 times.
6. Line end.

DEMO ^{Added multiline flag in demo to check for all cases}

P.S. You really need to specify which language you use so as to use an if condition something like below:

// true if above regex is satisfied and (&&) it does not (`!`) match `0`s `5` or more times

if(number.match(/^(\+\d{1,3}[- ]?)?\d{10}$/) && ! (number.match(/0{5,}/)) )

You can just use empty() - as seen in the documentation, it will return false if the variable has no value.

An example on that same page:

<?php
$var = 0;

// Evaluates to true because $var is empty
if (empty($var)) {
    echo '$var is either 0, empty, or not set at all';
}

// Evaluates as true because $var is set
if (isset($var)) {
    echo '$var is set even though it is empty';
}
?>

You can use isset if you just want to know if it is not NULL. Otherwise it seems empty() is just fine to use alone.

Since pandas 1.0 it became much more straightforward. This will read column 'ID' as dtype 'string':

pd.read_csv('sample.csv',dtype={'ID':'string'})

As we can see in this Getting started guide, 'string' dtype has been introduced (before strings were treated as dtype 'object').

This centers the "A" below the image:

<div style="text-align:center">
  <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/opentoselect.gif" />
  <br />
  A
</div>

That is ASP.Net and it would render the HTML as:

<div style="text-align:center">
<img id="Image1" src="Images/opentoselect.gif" style="border-width:0px;" />
<br />
A
</div>

This appears in the context of the Handle-Body-Idiom, also called Pimpl idiom. It allows one to keep the ABI (binary interface) of a library the same, by keeping actual data into another class object, which is merely referenced by a pointer held in an "handle" object, consisting of functions that delegate to that class "Body".

It's also useful to enable constant time and exception safe swap of two objects. For this, merely the pointer pointing to the body object has to be swapped.

I know it is an old topic, but when there is a very complex (especially asynchronous) validation process, there is a simple workaround:

<form id="form1">
<input type="button" onclick="javascript:submitIfVeryComplexValidationIsOk()" />
<input type="submit" id="form1_submit_hidden" style="display:none" />
</form>
...
<script>
function submitIfVeryComplexValidationIsOk() {
    var form1 = document.forms['form1']
    if (!form1.checkValidity()) {
        $("#form1_submit_hidden").click()
        return
    }

    if (checkForVeryComplexValidation() === 'Ok') {
         form1.submit()
    } else {
         alert('form is invalid')
    }
}
</script>

One line solution

myTextView.setText(Html.fromHtml("<p><u>I am Underlined text</u></p>"));

It is bit late but could be useful for someone.

I see a lot of answers have shifted to talk about using IDisposable for both managed and unmanaged resources. I'd suggest this article as one of the best explanations that I've found for how IDisposable should actually be used.

https://www.codeproject.com/Articles/29534/IDisposable-What-Your-Mother-Never-Told-You-About

For the actual question; should you use IDisposable to clean up managed objects that are taking up a lot of memory the short answer would be no. The reason is that once you Dispose of an IDisposable you should be letting it go out of scope. At that point any referenced child objects are also out of scope and will get collected.

The only real exception to this would be if you have a lot of memory tied up in managed objects and you've blocked that thread waiting for some operation to complete. If those objects where not going to be needed after that call completed then setting those references to null might allow the garbage collector to collect them sooner. But that scenario would represent bad code that needed to be refactored - not a use case of IDisposable.

There is no newline, just the div is a block element.

You can make the div inline by adding display: inline, which may be what you want.

This is an old question but it can be summed up as easily as this if you're using django-registration.

In your Log In and Log Out link (lets say in your page header) add the next parameter to the link which will go to login or logout. Your link should look like this.

<li><a href="http://www.noobmovies.com/accounts/login/?next={{ request.path | urlencode }}">Log In</a></li>

<li><a href="http://www.noobmovies.com/accounts/logout/?next={{ request.path | urlencode }}">Log Out</a></li>

That's simply it, nothing else needs to be done, upon logout they will immediately be redirected to the page they are at, for log in, they will fill out the form and it will then redirect to the page that they were on. Even if they incorrectly try to log in it still works.

Just use

If @searchType is null means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR @SearchType is NULL

If @searchType is an empty string means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR @SearchType = ''

If @searchType is null or an empty string means 'return the whole table' then use

WHERE p.[Type] = @SearchType OR Coalesce(@SearchType,'') = ''

Here is an overview of how the .NET framework and compiler versions are related, set and modified. Each project has a target .NET framework version(s), for example version 3.x or 2.x . The .NET framework contains the run time types and components.

The Visual Studio version installation and the .NET framework version determine the compatible c# language version and compiler options that can be used. The default c# version and options used in a Visual Studio project is the latest language version installed that is compatible with the .NET framework version being used.

To view or update the Framework or C# language within a project within Visual Studio 2011:

• right click the project within Solution Explorer and select Properties

• select 'Application' in the left navigation pane. Under Target framework: is the .NET framework version. Select the down arrow to see all available framework versions.

• select 'Build' in the left navigation pane. In the 'General' section of the pane next to 'Language Version:' is the c# compiler language version being used, for example 'default' or c# 5.0

• select the down arrow in the 'Language Version:" dropdown to see all available language versions. If 'default' is the c# version being used, the latest compatible c# language version will be used.

To see the exact compiler language version for 'default', enter the following in the developer command prompt for your installed Visual Studio version. For example, from the Windows Start icon select icon: "Developer Command Prompt for VS2011' and enter:

csc -langversion:Default

Microsoft (R) Visual C# Compiler version 4.7.3062.0 for c# 5

I'd use sed 's/;$//'. eg:

COMPANY_NAME=`cat file.txt | grep "company_name" | cut -d '=' -f 2 | sed 's/;$//'`

You can cut the url and use response.sendredirect(new url), this will bring you to the same page with the new url

additional you could add comma, period and minus (,.-)

The best way to solve this problem is, go to directory laravel/bootstrap/cache and delete config.php file. or you can rename it as well like config.php.old And your problem will be fix. Happy coding :-)

Just test if the array is empty.

$.getJSON(url,function(json){
    if ( json.length == 0 ) {
        console.log("NO DATA!")
    }
});

For Angular 1.3+ (credits to @Tom)

Use an alias expression (Docs: Angular 1.3.0: ngRepeat, scroll down to the Arguments section):

<div ng-repeat="person in data | filter:query as filtered">
</div>

For Angular prior to 1.3

Assign the results to a new variable (e.g. filtered) and access it:

<div ng-repeat="person in filtered = (data | filter: query)">
</div>

Display the number of results:

Showing {{filtered.length}} Persons

In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )

py -2 -m pip install pyfora

The canonical solution in the standard library is argparse (docs):

Here is an example:

from argparse import ArgumentParser

parser = ArgumentParser()
parser.add_argument("-f", "--file", dest="filename",
                    help="write report to FILE", metavar="FILE")
parser.add_argument("-q", "--quiet",
                    action="store_false", dest="verbose", default=True,
                    help="don't print status messages to stdout")

args = parser.parse_args()

argparse supports (among other things):

• Multiple options in any order.
• Short and long options.
• Default values.
• Generation of a usage help message.

It installs missing drivers when you plugin your device.

Obviously make sure you "debug usb" option in "developers options" is on.

Another thing, it's important to uninstall any device's installed driver before using it.

If you remove the files in the directory (with git rm as the other answers explain), then the directory no longer exists as far as git is concerned. You cannot commit an empty directory, nor can you remove one.

This is unlike subversion where you have to explicitly svn rm emptyfolder/, and is incidentally why the man page for git describes itself as "the stupid content tracker"

An answer on "How do I add an empty directory to a git repository" links to the FAQ on this subject:

Currently the design of the git index (staging area) only permits files to be listed, and nobody competent enough to make the change to allow empty directories has cared enough about this situation to remedy it.

Directories are added automatically when adding files inside them. That is, directories never have to be added to the repository, and are not tracked on their own.

You can say "git add <dir>" and it will add files in there.

If you really need a directory to exist in checkouts you should create a file in it. .gitignore works well for this purpose; you can leave it empty, or fill in the names of files you expect to show up in the directory.

use now() in any cell. then use that cell as a "dummy" parameter in a function. when now() changes every minute the formula recalculates. example: someFunction(a1,b1,c1) * (cell with now() / cell with now())

@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")

While it is true that you cannot change the type of the column after the DataTable is filled, you can change it after you call FillSchema, but before you call Fill. For example, say the 3rd column is the one you want to convert from double to Int32, you could use:

adapter.FillSchema(table, SchemaType.Source);
table.Columns[2].DataType = typeof (Int32);
adapter.Fill(table);

If you intend to change A, B, C.... you see high above the columns, you can not. You can hide A, B, C...: Button Office(top left) Excel Options(bottom) Advanced(left) Right looking: Display options fot this worksheet: Select the worksheet(eg. Sheet3) Uncheck: Show column and row headers Ok

Python is a case-sensitive language. All Python keywords are lowercase. Use if, not If.

Also, don't put a colon after the call to print(). Also, indent the print() and exit() calls, as Python uses indentation rather than brackets to represent code blocks.

And also, proceed = "y" or "Y" won't do what you want. Use proceed = "y" and if answer.lower() == proceed:, or something similar.

There's also the fact that your program will exit as long as the input value is not the single character "y" or "Y", which contradicts the prompting of "N" for the alternate case. Instead of your else clause there, use elif answer.lower() == info_incorrect:, with info_incorrect = "n" somewhere beforehand. Then just reprompt for the response or something if the input value was something else.

I'd recommend going through the tutorial in the Python documentation if you're having this much trouble the way you're learning now. http://docs.python.org/tutorial/index.html

Mutable default arguments don't generally do what you want. Instead, try this:

class Node:
     def __init__(self, wordList=None, adjacencyList=None):
        if wordList is None:
            self.wordList = []
        else:
             self.wordList = wordList 
        if adjacencyList is None:
            self.adjacencyList = []
        else:
             self.adjacencyList = adjacencyList 

Use a colon:

: ${A:=hello}

The colon is a null command that does nothing and ignores its arguments. It is built into bash so a new process is not created.

Using your radio button's ID, try rb.SelectedValue.

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

Comparator provides a way for you to provide custom comparison logic for types that you have no control over.

Comparable allows you to specify how objects that you are implementing get compared.

Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator.

Otherwise you can use Comparable.

dirname(__DIR__,level);
dirname(__DIR__,1);

level is how many times will you go back to the folder

You probably need to add the namespace:

    xmlns:local="clr-namespace:UserControlTest"
    Title="User Control Test" Height="300" Width="300">
    <local:UserControl1 />
</Window>

Try the following:

document.getElementById("successAndErrorMessages").innerHTML="someContent";

When you use an async function like

async () => {
    try {
        const response = await fetch(`https://www.reddit.com/r/${subreddit}.json`);
        const json = await response.json();
        setPosts(json.data.children.map(it => it.data));
    } catch (e) {
        console.error(e);
    }
}

it returns a promise and useEffect doesn't expect the callback function to return Promise, rather it expects that nothing is returned or a function is returned.

As a workaround for the warning you can use a self invoking async function.

useEffect(() => {
    (async function() {
        try {
            const response = await fetch(
                `https://www.reddit.com/r/${subreddit}.json`
            );
            const json = await response.json();
            setPosts(json.data.children.map(it => it.data));
        } catch (e) {
            console.error(e);
        }
    })();
}, []);

or to make it more cleaner you could define a function and then call it

useEffect(() => {
    async function fetchData() {
        try {
            const response = await fetch(
                `https://www.reddit.com/r/${subreddit}.json`
            );
            const json = await response.json();
            setPosts(json.data.children.map(it => it.data));
        } catch (e) {
            console.error(e);
        }
    };
    fetchData();
}, []);

the second solution will make it easier to read and will help you write code to cancel previous requests if a new one is fired or save the latest request response in state

Working codesandbox

As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog in your operation's dealloc method and confirm that's getting called.

You said:

I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit

The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self, or even just references an instance variable of self, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation subclass is released.

For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.

If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation is getting deallocated). A common example is the use of a repeating NSTimer. Or some custom delegate or other object that is erroneously maintaining a strong reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:

Or in Xcode 5:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:recyclerview-v7:21.0.0'
}

Just make your dependencies like above in build.gradle file, worked for me.

If the application is not doing anything in that 10 seconds, this will form a bad design only to make the user wait for 10 seconds doing nothing.

If there is something going on in that, or if you wish to implement 10 seconds delay splash screen,Here is the Code :

ProgressDialog pd;
pd = ProgressDialog.show(this,"Please Wait...", "Loading Application..", false, true);
pd.setCanceledOnTouchOutside(false);
Thread t = new Thread()
{ 
      @Override
      public void run()
      {
                try
                {
                    sleep(10000)  //Delay of 10 seconds
                } 
        catch (Exception e) {}
        handler.sendEmptyMessage(0);
        }
} ;
t.start();

//Handles the thread result of the Backup being executed.
private Handler handler = new Handler()
{
    @Override
    public void handleMessage(Message msg) 
    {
        pd.dismiss();
        //Start the Next Activity here...

    }
};

Update Jan. 2021, ten years later:

"git diff"^(man) showed a submodule working tree with untracked cruft as Submodule commit <objectname>-dirty, but a natural expectation is that the "-dirty" indicator would align with "git describe --dirty"^(man), which does not consider having untracked files in the working tree as source of dirtiness.
The inconsistency has been fixed with Git 2.31 (Q1 2021).

See commit 8ef9312 (10 Nov 2020) by Sangeeta Jain (sangu09).
^{(Merged by Junio C Hamano -- gitster -- in commit 0806279, 25 Jan 2021)}

diff: do not show submodule with untracked files as "-dirty"

^{Signed-off-by: Sangeeta Jain}

Git diff reports a submodule directory as -dirty even when there are only untracked files in the submodule directory.
This is inconsistent with what git describe --dirty^(man) says when run in the submodule directory in that state.

Make --ignore-submodules=untracked the default for git diff^(man) when there is no configuration variable or command line option, so that the command would not give '-dirty' suffix to a submodule whose working tree has untracked files, to make it consistent with git describe --dirty that is run in the submodule working tree.

And also make --ignore-submodules=none the default for git status^(man) so that the user doesn't end up deleting a submodule that has uncommitted (untracked) files.

git config now includes in its man page:

By default this is set to untracked so that any untracked submodules are ignored.

Original answer (2011)

As mentioned in Mark Longair's blog post Git Submodules Explained,

Versions 1.7.0 and later of git contain an annoying change in the behavior of git submodule.
Submodules are now regarded as dirty if they have any modified files or untracked files, whereas previously it would only be the case if HEAD in the submodule pointed to the wrong commit.

The meaning of the plus sign (+) in the output of git submodule has changed, and the first time that you come across this it takes a little while to figure out what’s going wrong, for example by looking through changelogs or using git bisect on git.git to find the change. It would have been much kinder to users to introduce a different symbol for “at the specified version, but dirty”.

You can fix it by:

• either committing or undoing the changes/evolutions within each of your submodules, before going back to the parent repo (where the diff shouldn't report "dirty" files anymore). To undo all changes to your submodule just cd into the root directory of your submodule and do git checkout .

dotnetCarpenter comments that you can do a: git submodule foreach --recursive git checkout .

• or add --ignore-submodules to your git diff, to temporarily ignore those "dirty" submodules.

New in Git version 1.7.2

As Noam comments below, this question mentions that, since git version 1.7.2, you can ignore the dirty submodules with:

git status --ignore-submodules=dirty

Create a selector into Drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
<item android:state_pressed="true">
   <shape>
         <solid android:color="@color/blue" />
   </shape>
</item>

<item android:state_pressed="false">
    <shape>
       <solid android:color="@android:color/transparent" />
    </shape>
</item>
</selector>

Add the property into your xml (where you declare the RecyclerView):

android:background="@drawable/selector"

You can also use,

parent.jQuery("#testdiv").attr("style", content from form);

It's looking for the file in the current directory.

First, go to that directory

cd /users/gcameron/Desktop/map

And then try to run it

python colorize_svg.py

Easily: Your data frame is A

b <- A[,1]
b <- b==1
b <- cumsum(b)

Then you get the column b.

Missing Dependency: libffi.so.5 is here :

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

You just have to replace the break with a return statement.

Think of the code inside the Foreach-Object as an anonymous function. If you have loops inside the function, just use the control keywords applying to the construction (continue, break, ...).

Take a look at antlr4. It will get you much farther along in creating a tree structure than regular expressions alone.

https://github.com/antlr/grammars-v4/tree/master/calculator (calculator.g4 contains the grammar you need)

In a nutshell, you define the grammar to parse an expression, use antlr to generate java code, and add callbacks to handle evaluation when the tree is being built.

When you are only dealing with a single table anyway, the biggest practical difference I have found is that DataSet has a "HasChanges" method but DataTable does not. Both have a "GetChanges" however, so you can use that and test for null.

Starting with parameter:

setup.exe /A

asks for saving included files (including MSI).

This may depend on the software which created the setup.exe.

sudo apt-get remove --purge mysql*

Remove the MySQL packages fully from the target system.

sudo apt-get purge mysql*

Remove all mysql related configuration files.

sudo apt-get autoremove

Clean up unused dependencies using autoremove command.

sudo apt-get autoclean

To clear all local repository in the target system.

sudo apt-get remove dbconfig-mysql

If you also want to delete your local/config files for dbconfig-mysql then this will work.

Here's the updated FIDDLE

Your HTML should look like this (I only added the button):

<a class="fragment" href="google.com">
    <button id="closeButton">close</button>
    <div>
        <img src ="http://placehold.it/116x116" alt="some description"/> 
        <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
        <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
        </p>
    </div>
</a>

and you should add the following CSS:

.fragment {
    position: relative;
}
#closeButton {
    position: absolute;
    top: 0;
    right: 0;
}

Then, to make the button actually work, you should add this javascript:

document.getElementById('closeButton').addEventListener('click', function(e) {
    e.preventDefault();
    this.parentNode.style.display = 'none';
}, false);

We're using e.preventDefault() here to prevent the anchor from following the link.

This solution will move the duplicates into one table and the uniques into another.

-- speed up creating uniques table if dealing with many rows
CREATE INDEX temp_idx ON jobs(site_id, company, title, location);

-- create the table with unique rows
INSERT jobs_uniques SELECT * FROM
    (
    SELECT * 
    FROM jobs
    GROUP BY site_id, company, title, location
    HAVING count(1) > 1
    UNION
    SELECT *
    FROM jobs
    GROUP BY site_id, company, title, location
    HAVING count(1) = 1
) x

-- create the table with duplicate rows
INSERT jobs_dupes 
SELECT * 
FROM jobs
WHERE id NOT IN
(SELECT id FROM jobs_uniques)

-- confirm the difference between uniques and dupes tables
SELECT COUNT(1)
AS jobs, 
(SELECT COUNT(1) FROM jobs_dupes) + (SELECT COUNT(1) FROM jobs_uniques)
AS sum
FROM jobs

As the others said, you can use Firebug, and that will sort you out no worries on Firefox. Chrome & Safari both have a built-in developer console which has an almost identical interface to Firebug's console, so your code should be portable across those browsers. For other browsers, there's Firebug Lite.

If Firebug isn't an option for you, then try this simple script:

function dump(obj) {
    var out = '';
    for (var i in obj) {
        out += i + ": " + obj[i] + "\n";
    }

    alert(out);

    // or, if you wanted to avoid alerts...

    var pre = document.createElement('pre');
    pre.innerHTML = out;
    document.body.appendChild(pre)
}

I'd recommend against alerting each individual property: some objects have a LOT of properties and you'll be there all day clicking "OK", "OK", "OK", "O... dammit that was the property I was looking for".

I am using jQuery here to get the entered text and wrapping all code in $(document).ready(). Make sure you have your API key ready for Google Places API Web service. Replace it in the below script file.

<input type="text" id="location">
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=[YOUR_KEY_HERE]&libraries=places"></script>
<script src="javascripts/scripts.js"></scripts>

Use script file to load the autocomplete class. Your scripts.js file will look something like this.

    // scripts.js custom js file
$(document).ready(function () {
   google.maps.event.addDomListener(window, 'load', initialize);
});

function initialize() {
    var input = document.getElementById('location');
    var autocomplete = new google.maps.places.Autocomplete(input);
}

GitHub now has an import option that lets you choose whatever you want your new imported repository public or private

run command

ng serve --host=0.0.0.0 --disable-host-check

this will disable host check and allow to access from outside(instead of localhost) with IP address

Both of your examples should behave pretty much the same.

A value returned inside a then() handler becomes the resolution value of the promise returned from that then(). If the value returned inside the .then is a promise, the promise returned by then() will "adopt the state" of that promise and resolve/reject just as the returned promise does.

In your first example, you return "bbb" in the first then() handler, so "bbb" is passed into the next then() handler.

In your second example, you return a promise that is immediately resolved with the value "bbb", so "bbb" is passed into the next then() handler. (The Promise.resolve() here is extraneous).

The outcome is the same.

If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.

Found it!

SELECT username, 
       account_status
  FROM dba_users;

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

Session["YourItem"] = "";

Works great in .net razor web pages.

So that I can ask it to get me the content/text in the div tag with class='container' contained within the body tag, Or something similar.

try: 
    from BeautifulSoup import BeautifulSoup
except ImportError:
    from bs4 import BeautifulSoup
html = #the HTML code you've written above
parsed_html = BeautifulSoup(html)
print(parsed_html.body.find('div', attrs={'class':'container'}).text)

You don't need performance descriptions I guess - just read how BeautifulSoup works. Look at its official documentation.

Go here and find the version you want to install and then download the correct msi file and run the installer. You cannot install node by running this command, also the error you receive is stating that npm is not on your path which suggests machine doesn't currently have node installed on it
