This is helpfull, its work for me..

$('.bd-example-modal-sm').on('hidden.bs.modal', function () { 
      $(this).find("select").val('').end(); // Clear dropdown content
      $("ul").empty();   // Clear li content 
});

Better to use arc4random_uniform. However, this isn't available below iOS 4.3. Luckily iOS will bind this symbol at runtime, not at compile time (so don't use the #if preprocessor directive to check if it's available).

The best way to determine if arc4random_uniform is available is to do something like this:

#include <stdlib.h>

int r = 0;
if (arc4random_uniform != NULL)
    r = arc4random_uniform (74);
else
    r = (arc4random() % 74);

In Ubuntu:

First You have to check that is the Docker Database port is Available in your system by following command -

sudo iptables -L -n

Sample OUTPUT:

Chain DOCKER (1 references)
target     prot opt source               destination         
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.2           tcp dpt:3306
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.3           tcp dpt:80
ACCEPT     tcp  --  0.0.0.0/0            172.17.0.3           tcp dpt:22

Here 3306 is used as Docker Database Port on 172.17.0.2 IP, If this port is not available Run the following command -

sudo iptables -A INPUT -p tcp --dport 3306 -j ACCEPT

Now, You can easily access the Docker Database from your local system by following configuration

  host: 172.17.0.2 
  adapter: mysql
  database: DATABASE_NAME
  port: 3307
  username: DATABASE_USER
  password: DATABASE_PASSWORD
  encoding: utf8

In CentOS:

First You have to check that is the Docker Database port is Available in your firewall by following command -

sudo firewall-cmd --list-all

Sample OUTPUT:

  target: default
  icmp-block-inversion: no
  interfaces: eno79841677
  sources: 
  services: dhcpv6-client ssh
  **ports: 3307/tcp**
  protocols: 
  masquerade: no
  forward-ports: 
  sourceports: 
  icmp-blocks: 
  rich rules:

Here 3307 is used as Docker Database Port on 172.17.0.2 IP, If this port is not available Run the following command -

sudo firewall-cmd --zone=public --add-port=3307/tcp

In server, You can add the port permanently

sudo firewall-cmd --permanent --add-port=3307/tcp
sudo firewall-cmd --reload

Now, You can easily access the Docker Database from your local system by the above configuration.

I came across this post when looking to parse an input like: word1,word2,...

none of the above helped me. solved it by using awk. If it helps someone:

for word in ${array}

You can use my highlight script from https://github.com/kepkin/dev-shell-essentials

It's better than grep cause you can highlight each match with it's own color.

This code might work:

//if the directory exists
 DWORD dwAttr = GetFileAttributes(str);
 if(dwAttr != 0xffffffff && (dwAttr & FILE_ATTRIBUTE_DIRECTORY)) 

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".

In your case, it will produce an error. :-)

Set assigns an object reference. For all other assignments the (implicit, optional, and little-used) Let statement is correct:

Set object = New SomeObject
Set object = FunctionReturningAnObjectRef(SomeArgument)

Let i = 0
Let i = FunctionReturningAValue(SomeArgument)

' or, more commonly '

i = 0
i = FunctionReturningAValue(SomeArgument)

I had to split a list for feature extraction in two parts lt,lc:

Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python. Thus,try to install python through installer itself,visit the site "https://www.python.org/downloads/" for more help. Thank you.

You can use an extension method.

public static class Extensions
{

    public static T ToEnum<T>(this string data) where T : struct
    {
        if (!Enum.TryParse(data, true, out T enumVariable))
        {
            if (Enum.IsDefined(typeof(T), enumVariable))
            {
                return enumVariable;
            }
        }

        return default;
    }

    public static T ToEnum<T>(this int data) where T : struct
    {
        return (T)Enum.ToObject(typeof(T), data);
    }
}

Use it like the below code:

Enum:

public enum DaysOfWeeks
{
    Monday = 1,
    Tuesday = 2,
    Wednesday = 3,
    Thursday = 4,
    Friday = 5,
    Saturday = 6,
    Sunday = 7,
}

Usage:

 string Monday = "Mon";
 int Wednesday = 3;
 var Mon = Monday.ToEnum<DaysOfWeeks>();
 var Wed = Wednesday.ToEnum<DaysOfWeeks>();

You can try same thing using Joins too..

With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

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

Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code

scGetruntotals.CommandTimeout = 180;

Note : the parameter value is in seconds.

Killing the Word process outright is possible (see some of the other replies), but outright rude and dangerous: what if the user has important unsaved changes in an open document? Not to mention the stale temporary files this will leave behind...

This is probably as far as you can go in this regard (VB.NET):

    Dim proc = Process.GetProcessesByName("winword")
    For i As Integer = 0 To proc.Count - 1
        proc(i).CloseMainWindow()
    Next i

This will close all open Word windows in an orderly fashion (prompting the user to save his/her work if applicable). Of course, the user can always click 'Cancel' in this scenario, so you should be able to handle this case as well (preferably by putting up a "please close all Word instances, otherwise we can't continue" dialog...)

In CakePHP 1.3, use 'default'=>value to select the default value in a select input:

$this->Form->input('Leaf.id', array('type'=>'select', 'label'=>'Leaf', 'options'=>$leafs, 'default'=>'3'));

You can do:

for f in *.txt; do (cat "${f}"; echo) >> finalfile.txt; done

Make sure the file finalfile.txt does not exist before you run the above command.

If you are allowed to use awk you can do:

awk 'FNR==1{print ""}1' *.txt > finalfile.txt

The ObjectiveC equivalent is:

    myView.translatesAutoresizingMaskIntoConstraints = NO;

    [[myView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor] setActive:YES];

    [[myView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor] setActive:YES];

I haven't found this to work on, say Application objects. I have however had success with

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

string rval = serializer.Serialize(myAppObj);

@cOnstructOr provided a great idea, but it left a comma in place

var today = new Date().toLocaleString('en-GB').split(' ')[0].slice(0,-1).split('/').reverse().join('-');

fixes that

Indeed as versions are changing, so is changing the user interface and options available on the menu. After reading most of the answers to these questions I had to guess what would work for Android Studio 1.1.0.

1. With your mouse, select the project at the main level (this is where it shows the name of your app).

2. Right click, and select the menu options New, Folder, Assets Folder.

3. After creating the assets folder, paste or copy in it, whatever JAR file you need for your library.

4. From Android Studio's main menu (top of the screen) select File -> Project Structure.

5. Then select your project name and go to the Dependencies tab.

6. Click on the plus sign (+) on the lower left of the dialog box and select file dependency.

7. Finally open the recently created assets folder, select the JAR files that you copied, and then click apply and OK.

Clean and rebuild your project.

There are lots of answers are already available but i think all of them are missing an important part of this question. Before reading data from an internal database or its table we have to understand how data is stored in it and then we can find the solution of the above question that is :

How can I read SMS messages from the device programmatically in Android?

So,In android SMS table is like look like this

Know,we can select whatever we want from the database.In our case we have only required

id,address and body

In case of reading SMS:

1.Ask for permissions

int REQUEST_PHONE_CALL = 1;

   if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_SMS}, REQUEST_PHONE_CALL);
        }

or

 <uses-permission android:name="android.permission.READ_SMS" />

2.Now your code goes like this

// Create Inbox box URI
Uri inboxURI = Uri.parse("content://sms/inbox");

// List required columns
String[] reqCols = new String[]{"_id", "address", "body"};

// Get Content Resolver object, which will deal with Content Provider
ContentResolver cr = getContentResolver();

// Fetch Inbox SMS Message from Built-in Content Provider
Cursor c = cr.query(inboxURI, reqCols, null, null, null);

// Attached Cursor with adapter and display in listview
adapter = new SimpleCursorAdapter(this, R.layout.a1_row, c,
        new String[]{"body", "address"}, new int[]{
        R.id.A1_txt_Msg, R.id.A1_txt_Number});
lst.setAdapter(adapter);

I hope this one will be helpful. Thanks.

This is how it's done using string interpolation C# 7

$"{myString:000}"

Assume that we need to view some data in command prompt which are coming from a database table. First we create a list. Team_Details is my property class.

    List<Team_Details> teamDetails = new List<Team_Details>();

Then you can connect to the database and do the data retrieving part and save it to the list as follows.

            string connetionString = "Data Source=.;Initial Catalog=your DB name;Integrated Security=True;MultipleActiveResultSets=True";
            using (SqlConnection conn = new SqlConnection(connetionString)){
            string getTeamDetailsQuery = "select * from Team";
            conn.Open();
            using (SqlCommand cmd = new SqlCommand(getTeamDetailsQuery, conn))
                    {
                        SqlDataReader rdr = cmd.ExecuteReader();
                    {
                        teamDetails.Add(new Team_Details
                        {
                            Team_Name = rdr.GetString(rdr.GetOrdinal("Team_Name")),
                            Team_Lead = rdr.GetString(rdr.GetOrdinal("Team_Lead")),
                        });
                    }

Then you can print this list in command prompt as follows.

foreach (Team_Details i in teamDetails)
                        {
                            Console.WriteLine(i.Team_Name);
                            Console.WriteLine(i.Team_Lead);
                        }

I had a similar problem when using TFS 2017. I was not able to push or pull GIT repositories. Eventually I reinstalled TFS 2017, making sure that I installed TFS 2017 with an SSH Port different from 22 (in my case, I chose 8022). After that, push and pull became possible against TFS using SSH.

SELECT owner, table_name
  FROM dba_tables

This is assuming that you have access to the DBA_TABLES data dictionary view. If you do not have those privileges but need them, you can request that the DBA explicitly grants you privileges on that table, or, that the DBA grants you the SELECT ANY DICTIONARY privilege or the SELECT_CATALOG_ROLE role (either of which would allow you to query any data dictionary table). Of course, you may want to exclude certain schemas like SYS and SYSTEM which have large numbers of Oracle tables that you probably don't care about.

Alternatively, if you do not have access to DBA_TABLES, you can see all the tables that your account has access to through the ALL_TABLES view:

SELECT owner, table_name
  FROM all_tables

Although, that may be a subset of the tables available in the database (ALL_TABLES shows you the information for all the tables that your user has been granted access to).

If you are only concerned with the tables that you own, not those that you have access to, you could use USER_TABLES:

SELECT table_name
  FROM user_tables

Since USER_TABLES only has information about the tables that you own, it does not have an OWNER column – the owner, by definition, is you.

Oracle also has a number of legacy data dictionary views-- TAB, DICT, TABS, and CAT for example-- that could be used. In general, I would not suggest using these legacy views unless you absolutely need to backport your scripts to Oracle 6. Oracle has not changed these views in a long time so they often have problems with newer types of objects. For example, the TAB and CAT views both show information about tables that are in the user's recycle bin while the [DBA|ALL|USER]_TABLES views all filter those out. CAT also shows information about materialized view logs with a TABLE_TYPE of "TABLE" which is unlikely to be what you really want. DICT combines tables and synonyms and doesn't tell you who owns the object.

@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver program on all your old classes. put these serialVersionUID values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: you should always have a serialVersionUID on all Serializable classes)

if the new versions are not serial compatible, then you need to do some magic with a custom readObject implementation (you would only need a custom writeObject if you were trying to write new class data which would be compatible with old code). generally speaking adding or removing class fields does not make a class serial incompatible. changing the type of existing fields usually will.

Of course, even if the new class is serial compatible, you may still want a custom readObject implementation. you may want this if you want to fill in any new fields which are missing from data saved from old versions of the class (e.g. you have a new List field which you want to initialize to an empty list when loading old class data).

Pass the intent with value on First Activity:

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);

Receive intent on second Activity;-

Intent intent = getIntent();
String user = intent.getStringExtra("uid");
String pass = intent.getStringExtra("pwd");

We use generally two method in intent to send the value and to get the value. For sending the value we will use intent.putExtra("key", Value); and during receive intent on another activity we will use intent.getStringExtra("key"); to get the intent data as String or use some other available method to get other types of data (Integer, Boolean, etc.). The key may be any keyword to identify the value means that what value you are sharing. Hope it will work for you.

This works for me:

C:\xampp\phpMyAdmin\config.inc.php

$cfg['Servers'][$i]['password'] = 'secret';

Edit: Before you got this error it is most likely that from phpmyadmin->Users you have added password for the root user. In my case that was "secret" so the above primer works for me BUT for you will work this:

$cfg['Servers'][$i]['password'] = 'Enter the password for root you have added before you got this error';

The code helped me to fulfill my requirement.

I have made some modifications and using a form I completed this. Here is my code-

Need a 'target' attribute for 'form' -- that's it!

Form

<form id="view_form" name="view_form" method="post" action="view_report.php"  target="Map" >
  <input type="text" value="<?php echo $sale->myvalue1; ?>" name="my_value1"/>
  <input type="text" value="<?php echo $sale->myvalue2; ?>" name="my_value2"/>
  <input type="button" id="download" name="download" value="View report" onclick="view_my_report();"   /> 
</form>

JavaScript

function view_my_report() {     
   var mapForm = document.getElementById("view_form");
   map=window.open("","Map","status=0,title=0,height=600,width=800,scrollbars=1");

   if (map) {
      mapForm.submit();
   } else {
      alert('You must allow popups for this map to work.');
   }
}

Full code is explained showing normal form and form elements.

You can use Bash's time keyword here with an appropriate format string

TIMEFORMAT='It takes %R seconds to complete this task...'
time {
    #command block that takes time to complete...
    #........
 }

Here's what the reference says about TIMEFORMAT:

The value of this parameter is used as a format string specifying how the timing information for pipelines prefixed with the time reserved word should be displayed. The ‘%’ character introduces an escape sequence that is expanded to a time value or other information. The escape sequences and their meanings are as follows; the braces denote optional portions.

%%

    A literal ‘%’.
%[p][l]R

    The elapsed time in seconds.
%[p][l]U

    The number of CPU seconds spent in user mode.
%[p][l]S

    The number of CPU seconds spent in system mode.
%P

    The CPU percentage, computed as (%U + %S) / %R. 

The optional p is a digit specifying the precision, the number of fractional digits after a decimal point. A value of 0 causes no decimal point or fraction to be output. At most three places after the decimal point may be specified; values of p greater than 3 are changed to 3. If p is not specified, the value 3 is used.

The optional l specifies a longer format, including minutes, of the form MMmSS.FFs. The value of p determines whether or not the fraction is included.

If this variable is not set, Bash acts as if it had the value

$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS'

If the value is null, no timing information is displayed. A trailing newline is added when the format string is displayed.

Here’s some code you can use to get a list of all the open windows. Actually, you get a dictionary where each item is a KeyValuePair where the key is the handle (hWnd) of the window and the value is its title. It also finds pop-up windows, such as those created by MessageBox.Show.

using System.Runtime.InteropServices;
using HWND = System.IntPtr;

/// <summary>Contains functionality to get all the open windows.</summary>
public static class OpenWindowGetter
{
  /// <summary>Returns a dictionary that contains the handle and title of all the open windows.</summary>
  /// <returns>A dictionary that contains the handle and title of all the open windows.</returns>
  public static IDictionary<HWND, string> GetOpenWindows()
  {
    HWND shellWindow = GetShellWindow();
    Dictionary<HWND, string> windows = new Dictionary<HWND, string>();

    EnumWindows(delegate(HWND hWnd, int lParam)
    {

      if (length == 0) return true;

      StringBuilder builder = new StringBuilder(length);
      GetWindowText(hWnd, builder, length + 1);

      windows[hWnd] = builder.ToString();

You're looking for the onblur event. Look here, for more details.

If you do the changes in management studio and generate scripts it makes a new table and inserts the old data into that with the changed data types. Here is a small example changing two column’s data types

You should use $no_proxy env variable (lower-case). Please consult https://wiki.archlinux.org/index.php/proxy_settings for examples.

Also, there was a bug at curl long time ago http://sourceforge.net/p/curl/bugs/185/ , maybe you are using an ancient curl version that includes this bug.

As per Nawfal's answer, IF statements need to be in a procedure. I found this post that shows a brilliant example of using your script in a procedure while still developing and testing. Basically, you create, call then drop the procedure:

https://gist.github.com/jeremyjarrell/6083251

If you have Python 2.6 or newer, use format:

'{0:.3g}'.format(num)

For Python 2.5 or older:

'%.3g'%(num)

Explanation:

{0}tells format to print the first argument -- in this case, num.

Everything after the colon (:) specifies the format_spec.

.3 sets the precision to 3.

g removes insignificant zeros. See http://en.wikipedia.org/wiki/Printf#fprintf

For example:

tests=[(1.00, '1'),
       (1.2, '1.2'),
       (1.23, '1.23'),
       (1.234, '1.23'),
       (1.2345, '1.23')]

for num, answer in tests:
    result = '{0:.3g}'.format(num)
    if result != answer:
        print('Error: {0} --> {1} != {2}'.format(num, result, answer))
        exit()
    else:
        print('{0} --> {1}'.format(num,result))

yields

1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23

Using Python 3.6 or newer, you could use f-strings:

In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'

The new version of Qt Creator also has a "profile" build option between debug and release. Here's how I'm detecting that:

CONFIG(debug, debug|release) {  DEFINES += DEBUG_MODE }
else:CONFIG(force_debug_info) { DEFINES += PROFILE_MODE }
else {                          DEFINES += RELEASE_MODE }

This worked for me:

sequencerPlayLabel.font = [UIFont fontWithName:kTypeFont size:kTypeFontSize];

This answer should be helpful if you don't want to use any other modules besides datetime.

datetime.utcfromtimestamp(timestamp) returns a naive datetime object (not an aware one). Aware ones are timezone aware, and naive are not. You want an aware one if you want to convert between timezones (e.g. between UTC and local time).

If you aren't the one instantiating the date to start with, but you can still create a naive datetime object in UTC time, you might want to try this Python 3.x code to convert it:

import datetime

d=datetime.datetime.strptime("2011-01-21 02:37:21", "%Y-%m-%d %H:%M:%S") #Get your naive datetime object
d=d.replace(tzinfo=datetime.timezone.utc) #Convert it to an aware datetime object in UTC time.
d=d.astimezone() #Convert it to your local timezone (still aware)
print(d.strftime("%d %b %Y (%I:%M:%S:%f %p) %Z")) #Print it with a directive of choice

Be careful not to mistakenly assume that if your timezone is currently MDT that daylight savings doesn't work with the above code since it prints MST. You'll note that if you change the month to August, it'll print MDT.

Another easy way to get an aware datetime object (also in Python 3.x) is to create it with a timezone specified to start with. Here's an example, using UTC:

import datetime, sys

aware_utc_dt_obj=datetime.datetime.now(datetime.timezone.utc) #create an aware datetime object
dt_obj_local=aware_utc_dt_obj.astimezone() #convert it to local time

#The following section is just code for a directive I made that I liked.
if sys.platform=="win32":
    directive="%#d %b %Y (%#I:%M:%S:%f %p) %Z"
else:
    directive="%-d %b %Y (%-I:%M:%S:%f %p) %Z"

print(dt_obj_local.strftime(directive))

If you use Python 2.x, you'll probably have to subclass datetime.tzinfo and use that to help you create an aware datetime object, since datetime.timezone doesn't exist in Python 2.x.

When you #include a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal variable is defined in the source so it will work no matter how it's declared.

Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.

the solution is easy: execute via sh

... -exec sh -c "zcat {} | agrep -dEOE 'grep' " \;

Provided that you are extending JFrame:

public void run() {
    MyFrame myFrame = new MyFrame();
    myFrame.setVisible(true);
    myFrame.setExtendedState(myFrame.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}

You cannot select a row like that. You have to specify a field whose values will be 3

Here is a query that will work, if the field you are comparing against is id

select * from customer where `id` = 3

i got the same problem and i notice that my security config has diferent TAGS like the @Xenolion answer says

<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </domain-config>
</network-security-config>

so i change the TAGS "domain-config" for "base-config" and works, like this:

<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </base-config>
</network-security-config>

Same as AMIB answer, for soft delete error "Unknown column 'table_alias.deleted_at'", just add ->withTrashed() then handle it yourself like ->whereRaw('items_alias.deleted_at IS NULL')

If you have included the assembly in your project, you can do :

            var assemblies =
                AppDomain.CurrentDomain.GetAssemblies();


            foreach (var assem in assemblies)
            {
                    Console.WriteLine(assem.FullName);
            }

These functions are fraught with perils when sequence names, column names, table names or schema names have funny characters such as spaces, punctuation marks, and the like. I have written this:

CREATE OR REPLACE FUNCTION sequence_max_value(oid) RETURNS bigint
VOLATILE STRICT LANGUAGE plpgsql AS  $$
DECLARE
 tabrelid oid;
 colname name;
 r record;
 newmax bigint;
BEGIN
 FOR tabrelid, colname IN SELECT attrelid, attname
               FROM pg_attribute
              WHERE (attrelid, attnum) IN (
                      SELECT adrelid::regclass,adnum
                        FROM pg_attrdef
                       WHERE oid IN (SELECT objid
                                       FROM pg_depend
                                      WHERE refobjid = $1
                                            AND classid = 'pg_attrdef'::regclass
                                    )
          ) LOOP
      FOR r IN EXECUTE 'SELECT max(' || quote_ident(colname) || ') FROM ' || tabrelid::regclass LOOP
          IF newmax IS NULL OR r.max > newmax THEN
              newmax := r.max;
          END IF;
      END LOOP;
  END LOOP;
  RETURN newmax;
END; $$ ;

You can call it for a single sequence by passing it the OID and it will return the highest number used by any table that has the sequence as default; or you can run it with a query like this, to reset all the sequences in your database:

 select relname, setval(oid, sequence_max_value(oid))
   from pg_class
  where relkind = 'S';

Using a different qual you can reset only the sequence in a certain schema, and so on. For example, if you want to adjust sequences in the "public" schema:

select relname, setval(pg_class.oid, sequence_max_value(pg_class.oid))
  from pg_class, pg_namespace
 where pg_class.relnamespace = pg_namespace.oid and
       nspname = 'public' and
       relkind = 'S';

Note that due to how setval() works, you don't need to add 1 to the result.

As a closing note, I have to warn that some databases seem to have defaults linking to sequences in ways that do not let the system catalogs have full information of them. This happens when you see things like this in psql's \d:

alvherre=# \d baz
                     Tabla «public.baz»
 Columna |  Tipo   |                 Modificadores                  
---------+---------+------------------------------------------------
 a       | integer | default nextval(('foo_a_seq'::text)::regclass)

Note that the nextval() call in that default clause has a ::text cast in addition to the ::regclass cast. I think this is due to databases being pg_dump'ed from old PostgreSQL versions. What will happen is that the function sequence_max_value() above will ignore such a table. To fix the problem, you can redefine the DEFAULT clause to refer to the sequence directly without the cast:

alvherre=# alter table baz alter a set default nextval('foo_a_seq');
ALTER TABLE

Then psql displays it properly:

alvherre=# \d baz
                     Tabla «public.baz»
 Columna |  Tipo   |             Modificadores              
---------+---------+----------------------------------------
 a       | integer | default nextval('foo_a_seq'::regclass)

As soon as you've fixed that, the function works correctly for this table as well as all others that might use the same sequence.

The accepted answer lists only the filenames, but to get the top 5 files one can also use:

ls -lht | head -6

where:

-l outputs in a list format

-h makes output human readable (i.e. file sizes appear in kb, mb, etc.)

-t sorts output by placing most recently modified file first

head -6 will show 5 files because ls prints the block size in the first line of output.

I think this is a slightly more elegant and possibly more useful approach.

Example output:

total 26960312 -rw-r--r--@ 1 user staff 1.2K 11 Jan 11:22 phone2.7.py -rw-r--r--@ 1 user staff 2.7M 10 Jan 15:26 03-cookies-1.pdf -rw-r--r--@ 1 user staff 9.2M 9 Jan 16:21 Wk1_sem.pdf -rw-r--r--@ 1 user staff 502K 8 Jan 10:20 lab-01.pdf -rw-rw-rw-@ 1 user staff 2.0M 5 Jan 22:06 0410-1.wmv

Depending on your exact requirements, you may do best with a jagged array of sorts with:

List<string>[] results = new { new List<string>(), new List<string>() };

Or you may do well with a list of lists or some other such construct.

The accepted answer didn't work for me so I've found this solution.

It may be related to the HTML version as the most voted solution there states:

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

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

See the link for more info.

On a related note, if you only have the filename or relative path, dirname on its own won't help. For me, the answer ended up being readlink.

fname='txtfile'    
echo $(dirname "$fname")                # output: .
echo $(readlink -f "$fname")            # output: /home/me/work/txtfile

You can then combine the two to get just the directory.

echo $(dirname $(readlink -f "$fname")) # output: /home/me/work

DECIMAL(18,0) will allow 0 digits after the decimal point.

Use something like DECIMAL(18,4) instead that should do just fine!

That gives you a total of 18 digits, 4 of which after the decimal point (and 14 before the decimal point).

If you don't have a company, leave your name, it doesn't matter as long as both bundle id in info.plist file and the one you've submitted in iTunes Connect match.

In Bundle ID Suffix you should write full name of bundle ID.

Example:

Bundle ID suffix = thebestapp (NOT CORRECT!!!!)

Bundle ID suffix = com.awesomeapps.thebestapp (CORRECT!!)

The reason for this is explained in the Developer Portal:

The App ID string contains two parts separated by a period (.) — an App ID Prefix (your Team ID by default, e.g. ABCDE12345), and an App ID Suffix (a Bundle ID search string, e.g. com.mycompany.appname). [emphasis added]

So in this case the suffix is the full string com.awesomeapps.thebestapp.

A web api endpoint (controller) is a single resource that accepts get/post/put/delete verbs. It is not a normal MVC controller.

Necessarily, at /api/VTRouting there can only be one HttpPost method that accepts the parameters you are sending. The function name does not matter, as long as you are decorating with the [http] stuff. I've never tried, though.

Edit: This does not work. In resolving, it seems to go by the number of parameters, not trying to model-bind to the type.

You can overload the functions to accept different parameters. I am pretty sure you would be OK if you declared it the way you do, but used different (incompatible) parameters to the methods. If the params are the same, you are out of luck as model binding won't know which one you meant.

[HttpPost]
public MyResult Route(MyRequestTemplate routingRequestTemplate) {...}

[HttpPost]
public MyResult TSPRoute(MyOtherTemplate routingRequestTemplate) {...}

This part works

The default template they give when you create a new one makes this pretty explicit, and I would say you should stick with this convention:

public class ValuesController : ApiController
{
    // GET is overloaded here.  one method takes a param, the other not.
    // GET api/values  
    public IEnumerable<string> Get() { .. return new string[] ... }
    // GET api/values/5
    public string Get(int id) { return "hi there"; }

    // POST api/values (OVERLOADED)
    public void Post(string value) { ... }
    public void Post(string value, string anotherValue) { ... }
    // PUT api/values/5
    public void Put(int id, string value) {}
    // DELETE api/values/5
    public void Delete(int id) {}
}

If you want to make one class that does many things, for ajax use, there is no big reason to not use a standard controller/action pattern. The only real difference is your method signatures aren't as pretty, and you have to wrap things in Json( returnValue) before you return them.

Edit:

Overloading works just fine when using the standard template (edited to include) when using simple types. I've gone and tested the other way too, with 2 custom objects with different signatures. Never could get it to work.

• Binding with complex objects doesn't look "deep", so thats a no-go
• You could get around this by passing an extra param, on the query string
• A better writeup than I can give on available options

This worked for me in this case, see where it gets you. Exception for testing only.

public class NerdyController : ApiController
{
    public void Post(string type, Obj o) { 
        throw new Exception("Type=" + type + ", o.Name=" + o.Name ); 
    }
}

public class Obj {
    public string Name { get; set; }
    public string Age { get; set; }
}

And called like this form the console:

$.post("/api/Nerdy?type=white", { 'Name':'Slim', 'Age':'21' } )

The existing answers are correct, but sometimes you aren't actually returning something explicitly with a Write-Output or a return, yet there is some mystery value in the function results. This could be the output of a builtin function like New-Item

PS C:\temp> function ContrivedFolderMakerFunction {
>>    $folderName = [DateTime]::Now.ToFileTime()
>>    $folderPath = Join-Path -Path . -ChildPath $folderName
>>    New-Item -Path $folderPath -ItemType Directory
>>    return $true
>> }
PS C:\temp> $result = ContrivedFolderMakerFunction
PS C:\temp> $result


    Directory: C:\temp


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----         2/9/2020   4:32 PM                132257575335253136
True

All that extra noise of the directory creation is being collected and emitted in the output. The easy way to mitigate this is to add | Out-Null to the end of the New-Item statement, or you can assign the result to a variable and just not use that variable. It would look like this...

PS C:\temp> function ContrivedFolderMakerFunction {
>>    $folderName = [DateTime]::Now.ToFileTime()
>>    $folderPath = Join-Path -Path . -ChildPath $folderName
>>    New-Item -Path $folderPath -ItemType Directory | Out-Null
>>    # -or-
>>    $throwaway = New-Item -Path $folderPath -ItemType Directory 
>>    return $true
>> }
PS C:\temp> $result = ContrivedFolderMakerFunction
PS C:\temp> $result
True

New-Item is probably the more famous of these, but others include all of the StringBuilder.Append*() methods, as well as the SqlDataAdapter.Fill() method.

The answer is given in @dku-rajkumar post.

ArrayList commonList = CollectionUtils.retainAll(list1,list2);

The basic problem while migrating from MySQL I faced was, I thought of the term database to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin, the result would not be as expected. As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.

For this, we can use the SET search_path command. This does switch the current schema to the specified schema name for the current session.

example:

SET search_path = different_schema_name;

This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf file.

You'll need to use an Iterator to loop through the keys to get their values.

Here's a Kotlin implementation, you will realised that the way I got the string is using optString(), which is expecting a String or a nullable value.

val keys = jsonObject.keys()
while (keys.hasNext()) {
    val key = keys.next()
    val value = targetJson.optString(key)        
}

Date is not an Integer in VB(A), it is a Double.

You can get a Date's value by passing it to CDbl().

CDbl(Now())      ' 40877.8052662037 

From the documentation:

The 1900 Date System

In the 1900 date system, the first day that is supported is January 1, 1900. When you enter a date, the date is converted into a serial number that represents the number of elapsed days starting with 1 for January 1, 1900. For example, if you enter July 5, 1998, Excel converts the date to the serial number 35981.

So in the 1900 system, 40877.805... represents 40,876 days after January 1, 1900 (29 November 2011), and ~80.5% of one day (~19:19h). There is a setting for 1904-based system in Excel, numbers will be off when this is in use (that's a per-workbook setting).

To get the integer part, use

Int(CDbl(Now())) ' 40877

which would return a LongDouble with no decimal places (i.e. what Floor() would do in other languages).

Using CLng() or Round() would result in rounding, which will return a "day in the future" when called after 12:00 noon, so don't do that.

Armin's answer is so useful, thank you. #2 is what's most important to know when trying to set up unload events that work in most browsers: you cannot alert() or confirm(), but returning a string will generate a confirm modal.

But I found that even with just returning a string, I had some cross-browser issues specific to Mootools (using version 1.4.5 in this instance). This Mootools-specific implementation worked great in Firefox, but did not result in a confirm popup in Chrome or Safari:

window.addEvent("beforeunload", function() {
    return "Are you sure you want to leave this page?";
});

So in order to get my onbeforeonload event to work across browsers, I had to use the JavaScript native call:

window.onbeforeunload = function() {
    return "Are you sure you want to leave this page?";
}

Not sure why this is the case, or if it's been fixed in later versions of Mootools.

I searched over and over this solution works like a charm ::

Garbage collection refers to the process of automatically freeing memory on the heap by deleting objects that are no longer reachable in your program. The heap is a memory which is referred to as the free store, represents a large pool of unused memory allocated to your Java application.

Using a normal css selector:

$('.sys input[type=text], .sys select').each(function() {...})

If you don't like the repetition:

$('.sys').find('input[type=text],select').each(function() {...})

Or more concisely, pass in the context argument:

$('input[type=text],select', '.sys').each(function() {...})

Note: Internally jQuery will convert the above to find() equivalent

http://api.jquery.com/jQuery/

Internally, selector context is implemented with the .find() method, so $('span', this) is equivalent to $(this).find('span').

I personally find the first alternative to be the most readable :), your take though

Building on Rick Viscomi's answer, try using the HTML Select Element's selectedOptions property:

let txtSelectedValuesObj = document.getElementById('txtSelectedValues');
[...txtSelectedValuesObj.selectedOptions].map(option => option.value);

In detail,

• selectedOptions returns a list of selected items.
• Specifically, it returns a read-only HTMLCollection containing HTMLOptionElements.
• ... is spread syntax. It expands the HTMLCollection's elements.
• [...] creates a mutable Array object from these elements, giving you an array of HTMLOptionElements.
• map() replaces each HTMLObjectElement in the array (here called option) with its value (option.value).

Dense, but it seems to work.

Watch out, selectedOptions isn't supported by IE!

This is doable, at least in theory, if you know the index:

System.out.println(team1.keySet().toArray()[0]);

keySet() returns a set, so you convert the set to an array.

The problem, of course, is that a set doesn't promise to keep your order. If you only have one item in your HashMap, you're good, but if you have more than that, it's best to loop over the map, as other answers have done.

If the problem occurs after multi touch you can disable multi touch with

android:splitMotionEvents="false" 

in layout file.

Use the checked attribute.

<input type="radio" name="imgsel"  value="" checked /> 

or

<input type="radio" name="imgsel"  value="" checked="checked" /> 

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

I would agree that Gareth's answer is probably most appropriate as a lightweight function/solution.

But I thought it would be helpful to note that if you are using NumPy or are considering it, there is a packaged function for this.

numpy.isclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False)

A little disclaimer though: installing NumPy can be a non-trivial experience depending on your platform.

Well, you're going to have to check for null somewhere. You could do something like this:

from item in db.vw_Dropship_OrderItems
         where (listStatus == null || listStatus.Contains(item.StatusCode)) 
            && (listMerchants == null || listMerchants.Contains(item.MerchantId))
         select item;

TL;DR - C# string extension method

I think the best solution to preserve the meaning of the string is to convert the characters instead of stripping them, which is well illustrated in the example crème brûlée to crme brle vs. creme brulee.

I checked out Alexander's comment above and saw the Lucene.Net code is Apache 2.0 licensed, so I've modified the class into a simple string extension method. You can use it like this:

var originalString = "crème brûlée";
var maxLength = originalString.Length; // limit output length as necessary
var foldedString = originalString.FoldToASCII(maxLength); 
// "creme brulee"

The function is too long to post in a StackOverflow answer (~139k characters of 30k allowed lol) so I made a gist and attributed the authors:

Hope that helps someone else, this is the most robust solution I've found!

it worked for me

$(document).scroll(function() {
    var y = $(document).scrollTop(), //get page y value 
        header = $("#myarea"); // your div id
    if(y >= 400)  {
        header.css({position: "fixed", "top" : "0", "left" : "0"});
    } else {
        header.css("position", "static");
    }
});

If both columns can contain NULL, but you still want to merge them to a single string, the easiest solution is to use CONCAT_WS():

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT_WS('', ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

This way you won't have to check for NULL-ness of each column separately.

Alternatively, if both columns are actually defined as NOT NULL, CONCAT() will be quite enough:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

As for COALESCE, it's a bit different beast: given the list of arguments, it returns the first that's not NULL.

In a maven project create a file src/main/resources/application.yml with the following content:

spring.profiles: integration
# use local or embedded mongodb at localhost:27017
---
spring.profiles: production
spring.data.mongodb.uri: mongodb://<user>:<passwd>@<host>:<port>/<dbname>

Spring Boot will automatically use this file to configure your application. Then you can start your spring boot application either with the integration profile (and use your local MongoDB)

java -jar -Dspring.profiles.active=integration your-app.jar

or with the production profile (and use your production MongoDB)

java -jar -Dspring.profiles.active=production your-app.jar

As you are using asp:Button which is a server control, post back will happen to avoid that go for html button,

asp:Button .... />

Type to

input type="button" .... />

Here 2 options for subsetting:

Using subset from base R:

library(ggplot2)
ggplot(subset(dat,ID %in% c("P1" , "P3"))) + 
         geom_line(aes(Value1, Value2, group=ID, colour=ID))

Using subset the argument of geom_line(Note I am using plyr package to use the special . function).

library(plyr)
ggplot(data=dat)+ 
  geom_line(aes(Value1, Value2, group=ID, colour=ID),
                ,subset = .(ID %in% c("P1" , "P3")))

You can also use the complementary subsetting:

subset(dat,ID != "P2")

I have been developing and designing iOS apps for a while and This is the best iOS design cheat sheet out there!

have fun :)!

Update: For iOS 8+, and the new devices (iPhone 6, 6 Plus, iPad Air) see this updated link.

Meta update: Iphone 6s/6s Plus have the same resolutions as iPhone 6/6 Plus respectively

This is an image from the new version of the article:

Inspired by the insightful answers on this page, I created a mixed approach, which I consider the simplest and more flexible one. What do you think?

First, I define the usage in a variable, which allows me to reuse it in different contexts. The format is very simple, almost WYSIWYG, without the need to add any control characters. This seems reasonably portable to me (I ran it on MacOS and Ubuntu)

__usage="
Usage: $(basename $0) [OPTIONS]

Options:
  -l, --level <n>              Something something something level
  -n, --nnnnn <levels>         Something something something n
  -h, --help                   Something something something help
  -v, --version                Something something something version
"

Then I can simply use it as

echo "$__usage"

or even better, when parsing parameters, I can just echo it there in a one-liner:

levelN=${2:?"--level: n is required!""${__usage}"}

Based @RBT's answer above, I tried Postman native app and want to give a couple of additional details.

In the latest postman desktop app, you can find the cookies option on the extreme right:

You can see the cookies for your localhost (these cookies are linked with the cookies in your chrome browser, although the app is running natively). Also you can set the cookies for a particular domain too.

Better to first compress catalog on remote server:

tar czfP backup.tar.gz /path/to/catalog

Secondly, download from remote:

scp [email protected]:/path/to/backup.tar.gz .

At the end, extract the files:

tar -xzvf backup.tar.gz

You have to change the values in the CATALINA_OPTS option defined in the Tomcat Catalina start file. To increase the PermGen memory change the value of the MaxPermSize variable, otherwise change the value of the Xmx variable.

Linux & Mac OS: Open or create setenv.sh file placed in the "bin" directory. You have to apply the changes to this line:

export CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"

Windows:

Open or create the setenv.bat file placed in the "bin" directory:

set CATALINA_OPTS=-server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

(Taken from my comment)

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

How about this?

CASE WHEN ProductAlternateKey is NOT NULL THEN
CONVERT(NVARCHAR(25), LTRIM(RTRIM(ProductAlternateKey))) 
FROM DimProducts
where ProductAlternateKey  like '46783815%'

Using <BR> is not allways enough. MS Outlook 2007 will ignore this if you dont tell outlook that it is a selfclosing html tag by using

 <BR />

Personally I feel that the query string method is more reliable than trying to set headers on the server - there's no guarantee that a proxy or browser won't just cache it anyway (some browsers are worse than others - naming no names).

I usually use Math.random() but I don't see anything wrong with using the date (you shouldn't be doing AJAX requests fast enough to get the same value twice).

Here I add proper answer

You can use this snippet code and customize. Here I use 2 child block.This should show center of the page. You can use one or multiple blocks.

<html>
<head>
<style>
#parent {
    width: 100%;
    border: solid 1px #aaa;
    text-align: center;
    font-size: 20px;
    letter-spacing: 35px;
    white-space: nowrap;
    line-height: 12px;
    overflow: hidden;
}

.child {
    width: 100px;
    height: 100px;
    border: solid 1px #ccc;
    display: inline-block;
    vertical-align: middle;
}
</style>
</head>

<body>

<div class="mydiv" id="parent">


<div class="child">
Block 1
</div>
<div class="child">
Block 2
</div>

</div>
</body>
</html>

if (value){
  value = (value.length > 1) ? value[0].toUpperCase() + value.substr(1).toLowerCase() : value.toUpperCase();
}

It might be a network issue. If you are running inside a virtual machine (e.g. VMWare or VirtualBox), try setting the network adapter mode from the default NAT to Bridged.

Also, cursor.lastrowid (a dbapi/PEP249 extension supported by MySQLdb):

>>> import MySQLdb
>>> connection = MySQLdb.connect(user='root')
>>> cursor = connection.cursor()
>>> cursor.execute('INSERT INTO sometable VALUES (...)')
1L
>>> connection.insert_id()
3L
>>> cursor.lastrowid
3L
>>> cursor.execute('SELECT last_insert_id()')
1L
>>> cursor.fetchone()
(3L,)
>>> cursor.execute('select @@identity')
1L
>>> cursor.fetchone()
(3L,)

cursor.lastrowid is somewhat cheaper than connection.insert_id() and much cheaper than another round trip to MySQL.

There are so many reasons for this error.I also got one and solved it.

It may be possible that you are adding a third party framework and not including it in the Copy Bundle Resources.That solved the problem for me.

Do this as follows. Go to Target -> BuildPhases -> CopyBundleResources -> Drag and drop your framework and run the code.

A better solution to convert Decimal To HexaDecimal and this one is less complex

import java.util.Scanner;
public class DecimalToHexa
{
    public static void main(String ar[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter a Decimal number: ");
        int n=sc.nextInt();
        if(n<0)
        {
            System.out.println("Enter a positive integer");
            return;
        }
        int i=0,d=0;
        String hx="",h="";
        while(n>0)
        {
            d=n%16;`enter code here`
            n/=16;
            if(d==10)h="A";
            else if(d==11)h="B";
            else if(d==12)h="C";
            else if(d==13)h="D";
            else if(d==14)h="E";
            else if(d==15)h="F";
            else h=""+d;            
            hx=""+h+hx;
        }
        System.out.println("Equivalent HEXA: "+hx);
    }
}        

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

If your .htaccess file is ok and the problem persist try to make the AllowOverride directive enabled in your httpd.conf. If the AllowOverride directive is set to None in your Apache httpd.config file, then .htaccess files are completely ignored. Example of enabled AllowOverride directive in httpd.config:

 <Directory />
    Options FollowSymLinks
    **AllowOverride All**
 </Directory>

Therefor restart your server.

In Chrome Browser go to setting , clear browsing history and then reload the page

If you want to search for the last instance of a string in a text, you can run rfind.

Example:

   s="Hello"
   print s.rfind('l')

output: 3

*no import needed

Complete syntax:

stringEx.rfind(substr, beg=0, end=len(stringEx))

Just to sum things up (git v. 1.7.2.1):

1. do a regular git clone where you want the repo (gets everything to date — I know, not what is wanted, we're getting there)
2. git checkout <sha1 rev> of the rev you want
3. git reset --hard
4. git checkout -b master

For those, who may want to download query result in CSV format but doesn't have access the server file but the database. First of all, it's not linux command. Steps are bellow:

1. Create a view with the query. For example: (Create VIEW v as (Select * from user where status = 0))
2. The view will be created under the view section of your database.
3. Now export the view as CSV.
4. If you need the table column as header of CSV, set Export method: to Custom - display all possible options and check Put columns names in the first row.

In C++20 you'll be able to use std::format to do this:

std::cout << std::format("a is {:x}; b is {:x}\n", a, b);

Output:

a is 0; b is ff

In the meantime you can use the {fmt} library, std::format is based on. {fmt} also provides the print function that makes this even easier and more efficient (godbolt):

fmt::print("a is {:x}; b is {:x}\n", a, b);

Disclaimer: I'm the author of {fmt} and C++20 std::format.

Socket are characterized by their domain, type and transport protocol. Common domains are:

1. AF_UNIX: address format is UNIX pathname

2. AF_INET: address format is host and port number

(there are actually many other options which can be used here for specialized purposes).usually we use AF_INET for socket programming

Annotation Approach

@ComponentScan({ "x.y.z", "x.y.z.dao" })

I would say you don't need to have the DEFAULT CURRENT_TIMESTAMP on your ts_update: if it is empty, then it is not updated, so your 'last update' is the ts_create.

You need to check the keycloak admin console for fronted configuration. It must be wrongly configured for redirect url and web origins.

Suposse you have

Class1

public class Class1 {
    //Your class code above
}

Class2

public class Class2 {
}

and then you can use Class2 in different ways.

Class Field

public class Class1{
    private Class2 class2 = new Class2();
}

Method field

public class Class1 {
    public void loginAs(String username, String password)
    {
         Class2 class2 = new Class2();
         class2.invokeSomeMethod();
         //your actual code
    }
}

Static methods from Class2 Imagine this is your class2.

public class Class2 {
     public static void doSomething(){
     }
}

from class1 you can use doSomething from Class2 whenever you want

public class Class1 {
    public void loginAs(String username, String password)
    {
         Class2.doSomething();
         //your actual code
    }
}

In perl

perl -ane '{ if(m/[[:^ascii:]]/) { print  } }' fileName > newFile

I want to write a program that (...) creates the directory and a (...) file inside of it

because this is a very common question, here is the code to create multiple levels of directories and than call fopen. I'm using a gnu extension to print the error message with printf.

void rek_mkdir(char *path) {
    char *sep = strrchr(path, '/');
    if(sep != NULL) {
        *sep = 0;
        rek_mkdir(path);
        *sep = '/';
    }
    if(mkdir(path, 0777) && errno != EEXIST)
        printf("error while trying to create '%s'\n%m\n", path); 
}

FILE *fopen_mkdir(char *path, char *mode) {
    char *sep = strrchr(path, '/');
    if(sep) { 
        char *path0 = strdup(path);
        path0[ sep - path ] = 0;
        rek_mkdir(path0);
        free(path0);
    }
    return fopen(path,mode);
}

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

Officially not.

But here's a patch: http://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

As mentionned in this post pandas: how to store a list in a dataframe?; the dtypes in the dataframe may influence the results, as well as calling a dataframe or not to be assigned to.

The sessions on PHP works with a Cookie type session, while on server-side the session information is constantly deleted.

For set the time life in php, you can use the function session_set_cookie_params, before the session_start:

session_set_cookie_params(3600,"/");
session_start();

For ex, 3600 seconds is one hour, for 2 hours 3600*2 = 7200.

But it is session cookie, the browser can expire it by itself, if you want to save large time sessions (like remember login), you need to save the data in the server and a standard cookie in the client side.

You can have a Table "Sessions":

• session_id int
• session_hash varchar(20)
• session_data text

And validating a Cookie, you save the "session id" and the "hash" (for security) on client side, and you can save the session's data on the server side, ex:

On login:

setcookie('sessid', $sessionid, 604800);      // One week or seven days
setcookie('sesshash', $sessionhash, 604800);  // One week or seven days
// And save the session data:
saveSessionData($sessionid, $sessionhash, serialize($_SESSION)); // saveSessionData is your function

If the user return:

if (isset($_COOKIE['sessid'])) {
    if (valide_session($_COOKIE['sessid'], $_COOKIE['sesshash'])) {
        $_SESSION = unserialize(get_session_data($_COOKIE['sessid']));
    } else {
        // Dont validate the hash, possible session falsification
    }
}

Obviously, save all session/cookies calls, before sending data.

$('#select_id option:eq(0)').prop('selected', 'selected');

its good

You can create a new model to Deserialize your Json CustomerJson:

public class CustomerJson
{
    [JsonProperty("customer")]
    public Customer Customer { get; set; }
}

public class Customer
{
    [JsonProperty("first_name")]
    public string Firstname { get; set; }

    [JsonProperty("last_name")]
    public string Lastname { get; set; }

    ...
}

And you can deserialize your json easily :

JsonConvert.DeserializeObject<List<CustomerJson>>(json);

Hope it helps !

Then click on "continue", after "register" and you get it and you can download it.

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

/**
 * Document my Jenkinsfile's overall purpose here
 */

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

First you store your text file in to raw folder.

private void loadWords() throws IOException {
    Log.d(TAG, "Loading words...");
    final Resources resources = mHelperContext.getResources();
    InputStream inputStream = resources.openRawResource(R.raw.definitions);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

    try {
        String line;
        while ((line = reader.readLine()) != null) {
            String[] strings = TextUtils.split(line, "-");
            if (strings.length < 2)
                continue;
            long id = addWord(strings[0].trim(), strings[1].trim());
            if (id < 0) {
                Log.e(TAG, "unable to add word: " + strings[0].trim());
            }
        }
    } finally {
        reader.close();
    }
    Log.d(TAG, "DONE loading words.");
}

I had usb to usbc hub on my macbook pro which was blocking the device somehow, it worked when I connected it directly with the apple usbc to usb dongle.

There is another scenario where this issue reproduces (as in my case). When THE CLIENT REQUEST doesn't contain the right extension on the url, the controller can't identify the desired result format.

For example: the controller is set to respond_to :json (as a single option, without a HTML response)- while the client call is set to /reservations instead of /reservations.json.

Bottom line, change the client call to /reservations.json.

$('#mytable tr').each(function() {
    var customerId = $(this).find("td:first").html();    
});

What you are doing is iterating through all the trs in the table, finding the first td in the current tr in the loop, and extracting its inner html.

To select a particular cell, you can reference them with an index:

$('#mytable tr').each(function() {
    var customerId = $(this).find("td").eq(2).html();    
});

In the above code, I will be retrieving the value of the third row (the index is zero-based, so the first cell index would be 0)

Here's how you can do it without jQuery:

var table = document.getElementById('mytable'), 
    rows = table.getElementsByTagName('tr'),
    i, j, cells, customerId;

for (i = 0, j = rows.length; i < j; ++i) {
    cells = rows[i].getElementsByTagName('td');
    if (!cells.length) {
        continue;
    }
    customerId = cells[0].innerHTML;
}

?

Use IFS (internal field separator) tool in bash, defines the character using to separate lines into tokens, by default includes <tab> /<space> /<newLine>

step 1: Load the file data and insert into list:

# declaring array list and index iterator
declare -a array=()
i=0

# reading file in row mode, insert each line into array
while IFS= read -r line; do
    array[i]=$line
    let "i++"
    # reading from file path
done < "<yourFullFilePath>"

step 2: now iterate and print the output:

for line in "${array[@]}"
  do
    echo "$line"
  done

echo specific index in array: Accessing to a variable in array:

echo "${array[0]}"

if you continue to have problems with the native driver, you can also check out sleepy mongoose. It's a python REST server that you can simply access with node request to get to your Mongo instance. http://www.snailinaturtleneck.com/blog/2010/02/22/sleepy-mongoose-a-mongodb-rest-interface/

This is because of a huge view state, In my case I got lucky since I was not using the viewstate. I just added enableviewstate="false" on the form tag and view state went from 35k to 100 chars

It is probably the h1 tag causing the problem. Applying margin: 0; should fix the problem.

But you should use a CSS reset for every new project to eliminate browser consistencies and problems like yours. Probably the most famous one is Eric Meyer's: http://meyerweb.com/eric/tools/css/reset/

Normally, Spring should do the autowiring, as long as your abstract class is in the base-package provided for component scan.

See this and this for further reference.

@Service and @Component are both stereotypes that creates beans of the annotated type inside the Spring container. As Spring Docs state,

This annotation serves as a specialization of @Component, allowing for implementation classes to be autodetected through classpath scanning.

This should work:

listBox1.Items.Clear();

use the following code,

    iv.setImageResource(getResources().getIdentifier("apple", "drawable", getPackageName()));

I know you can look up IP address to get approximate location, but it's not always accurate. Perhaps they're using that?

update:

Typically, your browser uses information about the Wi-Fi access points around you to estimate your location. If no Wi-Fi access points are in range, or your computer doesn't have Wi-Fi, it may resort to using your computer's IP address to get an approximate location.

First of all, checked can have a value of checked, or an empty string.

$("input:checkbox").uniform();

$('#check1').live('click', function() {
    $('#check2').attr('checked', 'checked').uniform();
});

For those who must solve this problem using Oracle 9i (or earlier), you will probably need to use SYS_CONNECT_BY_PATH, since LISTAGG is not available.

To answer the OP, the following query will display the PID from Table A and concatenate all the DESC columns from Table B:

SELECT pid, SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY pid ORDER BY pid, seq) rnum, pid, description
       FROM (
              SELECT a.pid, seq, description
              FROM table_a a, table_b b
              WHERE a.pid = b.pid(+)
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1 AND PRIOR pid = pid
GROUP BY pid
ORDER BY pid;

There may also be instances where keys and values are all contained in one table. The following query can be used where there is no Table A, and only Table B exists:

SELECT pid, SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY pid ORDER BY pid, seq) rnum, pid, description
       FROM (
              SELECT pid, seq, description
              FROM table_b
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1 AND PRIOR pid = pid
GROUP BY pid
ORDER BY pid;

All values can be reordered as desired. Individual concatenated descriptions can be reordered in the PARTITION BY clause, and the list of PIDs can be reordered in the final ORDER BY clause.

Alternately: there may be times when you want to concatenate all the values from an entire table into one row.

The key idea here is using an artificial value for the group of descriptions to be concatenated.

In the following query, the constant string '1' is used, but any value will work:

SELECT SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY unique_id ORDER BY pid, seq) rnum, description
       FROM (
              SELECT '1' unique_id, b.pid, b.seq, b.description
              FROM table_b b
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1;

Individual concatenated descriptions can be reordered in the PARTITION BY clause.

Several other answers on this page have also mentioned this extremely helpful reference: https://oracle-base.com/articles/misc/string-aggregation-techniques

Solution which leverages CollectionUtils subtract method:

import static org.apache.commons.collections15.CollectionUtils.subtract;

public class CollectionUtils {
  static public <T> boolean equals(Collection<? extends T> a, Collection<? extends T> b) {
    if (a == null && b == null)
      return true;
    if (a == null || b == null || a.size() != b.size())
      return false;
    return subtract(a, b).size() == 0 && subtract(a, b).size() == 0;
  }
}

In addition to using Request.Form and Request.QueryString and depending on your specific scenario, it may also be useful to check the Page's IsPostBack property.

if (Page.IsPostBack)
{
  // HTTP Post
}
else
{
  // HTTP Get
}

This might be too late for your work, but here is how I did it. I want something run everyday at 1AM - I believe this is similar to what you are doing. Here is how I did it:

    STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL 1 HOUR)
  DO
    # Your awesome query

• TEXT and BLOB may by stored off the table with the table just having a pointer to the location of the actual storage. Where it is stored depends on lots of things like data size, columns size, row_format, and MySQL version.

• VARCHAR is stored inline with the table. VARCHAR is faster when the size is reasonable, the tradeoff of which would be faster depends upon your data and your hardware, you'd want to benchmark a real-world scenario with your data.

Since API 21 there is an option set letter spacing. You can call method setLetterSpacing or set it in XML with attribute letterSpacing.

If you have a base class with pure virtual function, make sure your base class constructor and destructor has body otherwise linker fails.

var webpack = require('webpack'),
    pkg     = require('./package.json'),  //loads npm config file
    html    = require('html-webpack-plugin');

module.exports = {
  context : __dirname + '/app',
  entry   : {
    app     : __dirname + '/app/index.js',
    vendor  : Object.keys(pkg.dependencies) //get npm vendors deps from config
  },
  output  : {
    path      : __dirname + '/dist',
    filename  : 'app.min-[hash:6].js'
  },
  plugins: [
    //Finally add this line to bundle the vendor code separately
    new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.min-[hash:6].js'),
    new html({template : __dirname + '/app/index.html'})
  ]
};

You can read more about this feature in official documentation.

the simplest way to convert a string that has a delimiter like a comma is just to use the split method

"1,2,3,4".split(',') # "1", "2", "3", "4"]

you can find more info on how to use the split method in the ruby docs

Divides str into substrings based on a delimiter, returning an array of these substrings.

If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.

If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters. If pattern contains groups, the respective matches will be returned in the array as well.

If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ‘ were specified.

If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.

I like a nice simple extension method

 public static string ToCsv(this List<string> itemList)
         {
             return string.Join(",", itemList);
         }

Then you can just call the method on the original list:

string CsvString = myList.ToCsv();

Cleaner and easier to read than some of the other suggestions.

Step1. Install bulma package using npm

npm install --save bulma

Step2. Open angular.json and update following code

...
 "styles": [
 "node_modules/bulma/css/bulma.css",
 "src/styles.scss"
 ],
...

That's it.

To easily expose Bulma’s tools, add stylePreprocessorOptions to angular.json.

...
 "styles": [
 "src/styles.scss",
 "node_modules/bulma/css/bulma.css"
  ],
 "stylePreprocessorOptions": {
 "includePaths": [
    "node_modules",
    "node_modules/bulma/sass/utilities"
 ]
},
...

Well getheight gets the height, and getwidth gets the width. But you're calling those methods too soon. If you're calling them in oncreate or onresume, the view isn't drawn yet. You have to call it after the view has been drawn.

To be quite honest, regular expressions are not the best idea for this type of parsing. The regular expression you posted will probably work great for simple cases, but if things get more complex you are going to have huge problems (same reason why you cant reliably parse HTML with regular expressions). I know you probably don't want to hear this, I know I didn't when I asked the same type of questions, but string parsing became WAY more reliable for me after I stopped trying to use regular expressions for everything.

jTopas is an AWESOME tokenizer that makes it quite easy to write parsers by hand (I STRONGLY suggest jtopas over the standard java scanner/etc.. libraries). If you want to see jtopas in action, here are some parsers I wrote using jTopas to parse this type of file

If you are parsing XML files, you should be using an xml parser library. Dont do it youself unless you are just doing it for fun, there are plently of proven options out there

Use the Len function

length = Len(myString)

in my case, the method: context.Database.CreateIfNotExists(); called up multiple times before create database and crashed an error A severe error occurred on the current command. The results, if any, should be discarded.

I also had issue with setting the width of TextBox in MVC3, while setting the Clsss attribute worked for TextArea control but not for TextBoxFor control or EditorFor control:

I tried following & that worked for me:

@Html.TextBoxFor(model => model.Title, new { Class = "textBox", style = "width:90%;" })

also in this case Validations are working perfectly.

Here are a couple that look pretty decent:

http://sourceforge.net/projects/smallhd/

http://sourceforge.net/projects/helpdeskcsharp/

Use:

php -i

command or add:

phpinfo();

to get the location of configuration file.

Update these variables according to your need and server

max_input_time = 24000
max_execution_time = 24000
upload_max_filesize = 12000M
post_max_size = 24000M
memory_limit = 12000M

On Linux you will need to restart nginx / apache and phpfpm service so the new ini settings are loaded. On xampp, ammps you can restart these from control panel that comes with such applications.

For the JS, try

data: {id: the_id}
...
success: function(data) {
        alert('the server returned ' + data;
    }

and

$the_id = intval($_POST['id']);

in PHP

Programmatically:

You can do programmatically using setTypeface() method:

Below is the code for default Typeface

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

and if you want to set custom Typeface:

textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic

XML:

You can set directly in XML file in <TextView /> like this:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

Or you can set your fav font (from assets). for more info see link

I am just using the java.net package. Here you can do the following:

...
import java.net.URI;
...

String myUrl = "http://stackoverflow.com";
URI myURI = new URI(myUrl);

Simply move the declaration outside of the if block.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store2_logo.gif";
    }
}

<a href="@Url.RouteUrl("HomePage")" class="logo"><img  alt="" src="@imgsrc"></a>

You could make it a bit cleaner.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="/content/images/uploaded/store2_logo.gif";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    }
}

in code

listView.setSelector(getResources().getDrawable(R.drawable.transparent));

and add small transparent image to drawable folder.

Like: transparent.xml

<?xml version="1.0" encoding="utf-8"?>    
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#00000000"/>
</shape>

There are 4 parameters to this problem

1. current image width iX
2. current image height iY
3. target viewport width cX
4. target viewport height cY

And there are 3 different conditional parameters

1. cX > cY ?
2. iX > cX ?
3. iY > cY ?

solution

1. Find the smaller side of the target view port F
2. Find the larger side of the current view port L
3. Find the factor of both F/L = factor
4. Multiply both sides of the current port with the factor ie, fX = iX * factor; fY = iY * factor

that's all you need to do.

//Pseudo code


iX;//current width of image in the client
iY;//current height of image in the client
cX;//configured width
cY;//configured height
fX;//final width
fY;//final height

1. check if iX,iY,cX,cY values are >0 and all values are not empty or not junk

2. lE = iX > iY ? iX: iY; //long edge

3. if ( cX < cY )
   then
4.      factor = cX/lE;     
   else
5.      factor = cY/lE;

6. fX = iX * factor ; fY = iY * factor ; 

This is a mature forum, I am not giving you code for that :)

Your code is correct you just used .div instead of div

HTML

<div class="ui grid container">
<div class="ui center aligned three column grid">
  <div class="column">
  </div>
  <div class="column">
    </div>
  </div>

CSS

div{
position: absolute;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -50px;
width: 100px;
height: 100px;

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

I had a similar problem. The fontsquirel demo page was working in FF but not my own page even though all files were coming from the same domain!

It turned out that I was linking my stylesheet with an absolute URL (http://example.com/style.css) so FF thought it was coming from a different domain. Changing my stylesheet link href to /style.css instead fixed things for me.

This should work on most databases. You can also select a blank string as your extra column like so:

Select
  Hat, Show, Boat, '' as SomeValue
From
  Objects

You might have not copied the MySQL connector/J jar file into the lib folder and then this file has to be there in the classpath.

If you have not done so, please let me know I shall elaborate the answer

As an extension of accepted answer Oracle internally uses ROW_NUMBER/RANK functions. OFFSET FETCH syntax is a syntax sugar.

It could be observed by using DBMS_UTILITY.EXPAND_SQL_TEXT procedure:

Preparing sample:

CREATE TABLE rownum_order_test (
  val  NUMBER
);

INSERT ALL
  INTO rownum_order_test
SELECT level
FROM   dual
CONNECT BY level <= 10;
COMMIT;

Query:

SELECT val
FROM   rownum_order_test
ORDER BY val DESC
FETCH FIRST 5 ROWS ONLY;

is regular:

SELECT "A1"."VAL" "VAL" 
FROM  (SELECT "A2"."VAL" "VAL","A2"."VAL" "rowlimit_$_0",
               ROW_NUMBER() OVER ( ORDER BY "A2"."VAL" DESC ) "rowlimit_$$_rownumber" 
      FROM "ROWNUM_ORDER_TEST" "A2") "A1" 
WHERE "A1"."rowlimit_$$_rownumber"<=5 ORDER BY "A1"."rowlimit_$_0" DESC;

No its not possible but you can make use of div and put table in div

<div style="height: 100px; overflow: auto">
  <table style="height: 500px;">
   ...
  </table>
</div>

Use numpy.full. Here's a Python that creates a gray, blue, green and red image and shows in a 2x2 grid.

import cv2
import numpy as np

gray_img = np.full((100, 100, 3), 127, np.uint8)

blue_img = np.full((100, 100, 3), 0, np.uint8)
green_img = np.full((100, 100, 3), 0, np.uint8)
red_img = np.full((100, 100, 3), 0, np.uint8)

full_layer = np.full((100, 100), 255, np.uint8)

# OpenCV goes in blue, green, red order
blue_img[:, :, 0] = full_layer
green_img[:, :, 1] = full_layer
red_img[:, :, 2] = full_layer

cv2.imshow('2x2_grid', np.vstack([
    np.hstack([gray_img, blue_img]), 
    np.hstack([green_img, red_img])
]))
cv2.waitKey(0)
cv2.destroyWindow('2x2_grid')

You have to pass the arguments in the terminal in order to store them in 'argv'. This variable holds the arguments you pass to your Python script when you run it. It later unpacks the arguments and store them in different variables you specify in the program e.g.

script, first, second = argv
print "Your file is:", script
print "Your first entry is:", first
print "Your second entry is:" second

Then in your command line you have to run your code like this,

$python ex14.py Hamburger Pizza

Your output will look like this:

Your file is: ex14.py
Your first entry is: Hamburger
Your second entry is: Pizza

Or a nested List (okay, the OP was for a single column and this is for multiple columns..):

        //Base list is a list of fields, ie a data record
        //Enclosing list is then a list of those records, ie the Result set
        List<List<String>> ResultSet = new List<List<String>>();

        using (SqlConnection connection =
            new SqlConnection(connectionString))
        {
            // Create the Command and Parameter objects.
            SqlCommand command = new SqlCommand(qString, connection);

            // Create and execute the DataReader..
            connection.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                var rec = new List<string>();
                for (int i = 0; i <= reader.FieldCount-1; i++) //The mathematical formula for reading the next fields must be <=
                {                      
                    rec.Add(reader.GetString(i));
                }
                ResultSet.Add(rec);

            }
        }

@AlexeiLevenkov pointed me at another "easiest way" namely the extension method. It takes just a little coding, then provides the absolute easiest way to read/write, plus it offers the flexibility to create variations according to your personal needs. Here is a complete example:

This defines the extension method on the string type. Note that the only thing that really matters is the function argument with extra keyword this, that makes it refer to the object that the method is attached to. The class name does not matter; the class and method must be declared static.

using System.IO;//File, Directory, Path

namespace Lib
{
    /// <summary>
    /// Handy string methods
    /// </summary>
    public static class Strings
    {
        /// <summary>
        /// Extension method to write the string Str to a file
        /// </summary>
        /// <param name="Str"></param>
        /// <param name="Filename"></param>
        public static void WriteToFile(this string Str, string Filename)
        {
            File.WriteAllText(Filename, Str);
            return;
        }

        // of course you could add other useful string methods...
    }//end class
}//end ns

This is how to use the string extension method, note that it refers automagically to the class Strings:

using Lib;//(extension) method(s) for string
namespace ConsoleApp_Sandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            "Hello World!".WriteToFile(@"c:\temp\helloworld.txt");
            return;
        }

    }//end class
}//end ns

I would never have found this myself, but it works great, so I wanted to share this. Have fun!

...
XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("","");
s.Serialize(xmlWriter, objectToSerialize, ns);

Okay you got the syntax wrong here, correct way to do this is:

var arr: Criminal[] = [];

I'm assuming you are using var so that means declaring it somewhere inside the func(),my suggestion would be use let instead of var.

If declaring it as c class property usse acces modifiers like private, public, protected.

If you want to select particular element use below code

var gridRowData = $("<your grid name>").data("kendoGrid");
var selectedItem = gridRowData.dataItem(gridRowData.select());
var quote = selectedItem["<column name>"];

Correct your Code like this:

try
{ //method try starts  
  String sql = "INSERT into TblName (col1, col2) VALUES(?, ?)";
  pStmt = obj.getConnection().prepareStatement(sql);
  pStmt.setLong(1, subscriberID);
  for (String language : additionalLangs) {
    pStmt.setInt(2, Integer.parseInt(language));
    pStmt.execute();
  }
} //method/try ends
finally
{ //finally starts
   pStmt.close()
} 

Are you sure, that you're really closing your pStatements, connections and results?

To analyze open objects you can implment a delegator pattern, which wraps code around your statemant, connection and result objects. So you'll see, if an object will successfully closed.

An Example for: pStmt = obj.getConnection().prepareStatement(sql);

    class obj{ 

    public Connection getConnection(){
    return new ConnectionDelegator(...here create your connection object and put it into ...);

    } 
}


class ConnectionDelegator implements Connection{
    Connection delegates;

    public ConnectionDelegator(Connection con){
       this.delegates = con;
    }

    public Statement prepareStatement(String sql){
        return delegates.prepareStatement(sql);
    }

    public void close(){
        try{
           delegates.close();
        }finally{
           log.debug(delegates.toString() + " was closed");
        }
    }
}

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

As others have mentioned, from C++17 onwards you can make use of structured bindings for multiple variable assignments.

Combining this with std::array and template argument deduction we can write a function that assigns a value to an arbitrary number of variables without repeating the type or value.

#include <iostream>
#include <array>

template <int N, typename T> auto assign(T value)
{
    std::array<T, N> out;
    out.fill(value);
    return out;
}

int main()
{
    auto [a, b, c] = assign<3>(1);

    for (const auto& v : {a, b, c})
    {
        std::cout << v << std::endl;
    }

    return 0;
}

Demo

Because strip() only strips trailing and leading characters, based on what you provided. I suggest:

>>> import re
>>> name = "Barack (of Washington)"
>>> name = re.sub('[\(\)\{\}<>]', '', name)
>>> print(name)
Barack of Washington

Use open(file, mode) for files. The mode is a variant of 'r' for read, 'w' for write, and possibly 'b' appended (e.g., 'rb') to open binary files. See the link below.

Use open with readline() or readlines(). The former will return a line at a time, while the latter returns a list of the lines.

Use split(delimiter) to split on the comma.

Lastly, you need to cast each item to an integer: int(foo). You'll probably want to surround your cast with a try block followed by except ValueError as in the link below.

You can also use 'multiple assignment' to assign a and b at once:

>>>a, b = map(int, "2342342,2234234".split(","))  
>>>print a  
2342342
>>>type(a)  
<type 'int'>

It uses only Bash builtins, and should handle files whose names contain newlines or other unusual characters.

$(: ...) is a little less ugly, but still not good.

In Android the "work queue processor" pattern is commonly used to offload tasks from an application's main thread.

Example: The design of the IntentService class.

The IntentService receives the Intents, launch a worker thread, and stops the service as appropriate.All requests are handled on a single worker thread.

Ok I did it with some trick ;) First build a UITextField and increased it's size like this :

CGRect frameRect = textField.frame;
        frameRect.size.height = 53;
        textField.frame = frameRect;

Then build a UITextView exactly in the same area that u made my UITextField, and deleted its background color. Now it looks like that u have a multiple lines TextField !

A referral is sent by an AD server when it doesn't have the information requested itself, but know that another server have the info. It usually appears in trust environment where a DC can refer to a DC in trusted domain.

In your case you are only specifying a domain, relying on automatic lookup of what domain controller to use. I think that you should try to find out what domain controller is used for the query and look if that one really holds the requested information.

If you provide more information on your AD setup, including any trusts/subdomains, global catalogues and the DNS resource records for the domain controllers it will be easier to help you.

Disclaimer: this fix works with Alpha44

I had the same issue and solved it by implementing the HashLocationStrategy listed in the Angular.io API Preview.

https://angular.io/docs/ts/latest/api/common/index/HashLocationStrategy-class.html

Start by importing the necessary directives

import {provide} from 'angular2/angular2';
import {
  ROUTER_PROVIDERS,
  LocationStrategy,
  HashLocationStrategy
} from 'angular2/router';

And finally, bootstrap it all together like so

bootstrap(AppCmp, [
  ROUTER_PROVIDERS,
  provide(LocationStrategy, {useClass: HashLocationStrategy})
]);

Your route will appear as http://localhost/#/route and when you refresh, it will reload at it's proper place.

Hope that helps!

1. You should not be updating 10k rows in a set unless you are certain that the operation is getting Page Locks (due to multiple rows per page being part of the UPDATE operation). The issue is that Lock Escalation (from either Row or Page to Table locks) occurs at 5000 locks. So it is safest to keep it just below 5000, just in case the operation is using Row Locks.

2. You should not be using SET ROWCOUNT to limit the number of rows that will be modified. There are two issues here:

   1. It has that been deprecated since SQL Server 2005 was released (11 years ago):

      Using SET ROWCOUNT will not affect DELETE, INSERT, and UPDATE statements in a future release of SQL Server. Avoid using SET ROWCOUNT with DELETE, INSERT, and UPDATE statements in new development work, and plan to modify applications that currently use it. For a similar behavior, use the TOP syntax

   2. It can affect more than just the statement you are dealing with:

      Setting the SET ROWCOUNT option causes most Transact-SQL statements to stop processing when they have been affected by the specified number of rows. This includes triggers. The ROWCOUNT option does not affect dynamic cursors, but it does limit the rowset of keyset and insensitive cursors. This option should be used with caution.

   Instead, use the TOP () clause.

3. There is no purpose in having an explicit transaction here. It complicates the code and you have no handling for a ROLLBACK, which isn't even needed since each statement is its own transaction (i.e. auto-commit).

4. Assuming you find a reason to keep the explicit transaction, then you do not have a TRY / CATCH structure. Please see my answer on DBA.StackExchange for a TRY / CATCH template that handles transactions:

   Are we required to handle Transaction in C# Code as well as in Store procedure

I suspect that the real WHERE clause is not being shown in the example code in the Question, so simply relying upon what has been shown, a better model would be:

DECLARE @Rows INT,
        @BatchSize INT; -- keep below 5000 to be safe

SET @BatchSize = 2000;

SET @Rows = @BatchSize; -- initialize just to enter the loop

BEGIN TRY    
  WHILE (@Rows = @BatchSize)
  BEGIN
      UPDATE TOP (@BatchSize) tab
      SET    tab.Value = 'abc1'
      FROM  TableName tab
      WHERE tab.Parameter1 = 'abc'
      AND   tab.Parameter2 = 123
      AND   tab.Value <> 'abc1' COLLATE Latin1_General_100_BIN2;
      -- Use a binary Collation (ending in _BIN2, not _BIN) to make sure
      -- that you don't skip differences that compare the same due to
      -- insensitivity of case, accent, etc, or linguistic equivalence.

      SET @Rows = @@ROWCOUNT;
  END;
END TRY
BEGIN CATCH
  RAISERROR(stuff);
  RETURN;
END CATCH;

By testing @Rows against @BatchSize, you can avoid that final UPDATE query (in most cases) because the final set is typically some number of rows less than @BatchSize, in which case we know that there are no more to process (which is what you see in the output shown in your answer). Only in those cases where the final set of rows is equal to @BatchSize will this code run a final UPDATE affecting 0 rows.

I also added a condition to the WHERE clause to prevent rows that have already been updated from being updated again.

Try this :

width:auto;
margin-right:50px;

or you can add the AutoCompleteBox into the toolbox by clicking on it and then Choose Items, go to WPF Components, type in the filter AutoCompleteBox, which is on the System.Windows.Controls namespace and the just drag into your xaml file. This is way much easier than doing these other stuff, since the AutoCompleteBox is a native control.

If you need a weak reference to the cell value:

object field = d.Rows[0][3]

or

object field = d.Rows[0].ItemArray[3]

Should do it

If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:

string field = d.Rows[0].Field<string>(3);

(make sure System.Data is in listed in the namespaces in this case)

Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)

From grep --help, but also see man grep:

Exit status is 0 if any line was selected, 1 otherwise; if any error occurs and -q was not given, the exit status is 2.

if grep --quiet MYSQL_ROLE=master /etc/aws/hosts.conf; then
  echo exists
else
  echo not found
fi

You may want to use a more specific regex, such as ^MYSQL_ROLE=master$, to avoid that string in comments, names that merely start with "master", etc.

This works because the if takes a command and runs it, and uses the return value of that command to decide how to proceed, with zero meaning true and non-zero meaning false—the same as how other return codes are interpreted by the shell, and the opposite of a language like C.

div is a block element, which always takes up its own line.

use the span tag instead

I'll answer for horizontal stretching of text, since the vertical is the easy part - just use "transform: scaleY()"

.stretched-text {
  letter-spacing: 2px;
  display: inline-block;
  font-size: 32px;
  transform: scaleY(0.5);
  transform-origin: 0 0;
  margin-bottom: -50%;
}
span {
  font-size: 16px;
  vertical-align: top;
}

<span class="stretched-text">this is some stretched text</span>
<span>and this is some random<br />triple line <br />not stretched text</span>

letter-spacing just adds space between letters, stretches nothing, but it's kinda relative

inline-block because inline elements are too restrictive and the code below wouldn't work otherwise

Now the combination that makes the difference

font-size to get to the size we want - that way the text will really be of the length it's supposed to be and the text before and after it will appear next to it (scaleX is just for show, the browser still sees the element at its original size when positioning other elements).

scaleY to reduce the height of the text, so that it's the same as the text beside it.

transform-origin to make the text scale from the top of the line.

margin-bottom set to a negative value, so that the next line will not be far below - preferably percentage, so that we won't change the line-height property. vertical-align set to top, to prevent the text before or after from floating to other heights (since the stretched text has a real size of 32px)

-- The simple span element has a font-size, only as a reference.

The question asked for a way to prevent the boldness of the text caused by the stretch and I still haven't given one, BUT the font-weight property has more values than just normal and bold.

I know, you just can't see that, but if you search for the appropriate fonts, you can use the more values.
